Rain, Rain, Go Away

rain and floodingMost of the service area covered by Polyjacking.com has had a lot more rain this summer than usual. In addition to ruining a lot of outdoor plans, the rainfall may have wreaked havoc with the foundation of your home or business.

If your building wasn’t flooded, why should you be worried about the amount of rain in your area?

Water and Soil

When there is a lot of rain, it has to go somewhere. Some of it may run into storm sewers or creeks or other planned run-off areas. Most of the time, though, it goes into the soil until the ground is saturated. The water-soaked soil can cause problems for concrete slabs and foundations.

Hydrostatic Pressure

When the soil is oversaturated, it can exert a tremendous amount of pressure on its surroundings. This is called hydrostatic pressure and it can damage a foundation wall completely. If the foundation of your building is under the strain of hydrostatic pressure, the walls may begin to bow or lean. Walls and slab floors may show cracking as the soil and water pushes against the rigid concrete.

Erosion

Water will take the path of least resistance and can erode the soil around it. When the soil gets washed away, it removes the support from around the foundation or slab. Voids can open underneath the concrete, allowing the slab to sink or crack.

Flooding

If the rain falls too fast or the ground is saturated, the water can flood buildings or enter cracks no bigger than a hair. Water can weaken concrete and put your slab or building in danger.

Water Damage Prevention

There are steps you can take to help keep your home or business dry. You can make sure that your gutters and downspouts are clear and emptying at least 10 feet from the foundation. In addition, companies like Pro Foundation Technology, Inc. can provide you with waterproofing techniques to keep the water out of your building.

Surface Drainage

Some options that can help with surface drainage include drywells, gutters, and French drains. It is important that you have good surface drainage or the water you keep out of your building will just come right back, trying to enter your foundation.

Exterior Drainage

To properly install exterior drainage, the outside of the building will have to be excavated, exposing the footing. Most reputable contractors will roll on or spray a polymer waterproofing product. A drain pipe system should be installed for continuous drainage. The drain can empty to a sump pump system or to daylight.

Interior Drainage

One of the most important parts of a waterproofing system is the implementation of a sealed interior drain tile system. Since the system is underneath the foundation, it is important that it is installed correctly from the start. Cracks in the walls and floor will need to be sealed with epoxy or polyurethane.

Sump Pump System

A sump pump system can move water out of the building, keeping water from flooding the structure. The system consists of a sump pump, a sump pit, and we recommend a battery back-up sump pump.

My Slab is Damaged, Now What?

industrial floor repairSo after all of the rain this summer you may be facing a damaged concrete slab or foundation, so what can you do? Before you call in someone to have the slab torn up, contact the experts at Polyjacking.com. We will come out and look at your property and determine if polyjacking is the solution you need. Polyjacking a slab is a LOT cheaper than destroying it and replacing the concrete.

The process is relatively easy and doesn’t require heavy machinery. Small holes are drilled in the concrete and polyurethane foam is injected under the slab. The foam expands, lifting the concrete and filling in any voids and cracks underneath the slab. The foam is water-resistant, so it won’t erode and the foam compacts the soil, making it more stable. By the time the equipment is removed and the area is cleaned up, you can use the slab. Curing time is about 15 minutes, so you won’t have to wait long to get back to business.

Contact the pros at Polyjacking.com to learn more about how using polyurethane foam to repair your concrete is the most cost-effective and long-lasting solution available.

 

Industrial Concrete Floor Repair

With all of the activity that takes place in warehouses, manufacturing plants, and other industrial buildings, it is easy to let the concrete floor to become damaged or worn out. There always seems to be something else that needs to be repaired or replaced, but if you let your commercial concrete floor problems grow, the time and money it will take to repair them will just get larger and larger.

Signs of Industrial Floor Repair Needs

industrial floor repairThere are some things that you can look for to decide if you need repairs done on the floor of your industrial facility.

Floor Cracks: Every concrete floor will develop cracks over the years and, in many cases, the cracks are harmless. There are some cracks that are structural in nature and those are the kinds that you need to pay attention to.

How can you tell if a crack in your concrete floor is cosmetic or structural? If the crack is wider than the thickness of a credit card or runs the length of the floor, there may be cause for concern. Also, if the crack is between two levels of the surface or the slab is tilted, you may have a concrete problem. There are some causes of these kinds of cracks. Either the slab has settled unevenly, or there is a void underneath the concrete. Regardless of the reason, it is important that you have a trusted professional repair contractor to inspect the concrete slab.

If the damage is caught early enough, a process like polyjacking or other slab lifting method could be used successfully. The concrete slab can be stabilized and the cracks filled, leaving you with a floor that is like new, preventing further damage from occurring.

Slab Deterioration: Because the slab is located inside a commercial facility, it is more likely to be subjected to heavy wear and tear. Forklifts and other machinery can wear off the top layer of the slab which is usually the hardest portion of the concrete. The softer part of the concrete will deteriorate quicker, causing more problems for the slab and for your employees to do their jobs.

It is important that the damage is stopped before it can become dangerous. The surface can be ground to a smooth surface and a penetrating sealer can be applied to harden the concrete. This new surface will allow your equipment to run along the surface safely.

Damaged Joints: If the joints in your slab were not filled with a flexible joint sealer, they will begin to chip and fail. The chips can begin to get big enough to jostle the forklift, the operator, and the load that they are carrying. This can cause injuries to the operator and other people around and also can damage products and equipment.

An experienced contractor should inspect the joints and determine the next course of action. This may involve rebuilding the joints and lifting the slabs to evenly match each other.

Industrial Floor Lifting

warehouse concrete repair Kansas CityThere are several methods of repairing a commercial concrete slab, but you will probably need something that won’t interfere too much with the daily operation of your facility. Some people think that you have to completely tear up the slab and start from scratch. Although this may be the best solution in some cases, many times you only need to lift the slab.

If you are looking for the most efficient, cost-effective, and environmentally sound method of slab repair, we strongly suggest using polyjacking. Polyurethane concrete lifting has been used extensively for over 30 years in all types of heavy-duty, real-world conditions and locations. The polyurethane foam can lift the slab to within a tenth of an inch of the desired height and will remain there. The structural integrity of the slab is maintained, through the use of smaller holes than a process like mudjacking would use.

The foam will seal the underside of the slab and fill in any voids located under the concrete. The foam is water-resistant, so it won’t wash away from erosion like the mud slurry in mudjacking.

You will be able to use the slab about 15 minutes after the foam is injected, unlike other methods that may take multiple days to set. By the time we have cleaned up and put the equipment away, you’ll be able to drive your equipment on the repaired slab.

St. Louis and Concrete Problems

The St. Louis area has had its share of extreme weather this winter. The extremely cold weather has caused pipes and water mains to freeze break causing water-related problems around the area. According to television station KMOV, Missouri American Water is likely to break the current record for most water main breaks in one month, with a prediction of over a thousand breaks total.

Concrete Problems in St. Louis

water main breaks in St. LouisIn addition to losing water to your St. Louis home or business, a broken water main or pipe can cause problems for your concrete. The already frozen ground will be flooded with gallons of water with nowhere to go. The pressure will lift your concrete slabs, cracking them or causing a tripping hazard. Freezing water expands, so if the water from the broken main infiltrates a crack in your concrete, it can easily cause the crack to grow.

The good thing about a St. Louis winter is that it will get warm again, so even if the water is frozen now, it will eventually thaw out. However, when that happens, the soil will be oversaturated and lose some of its stability. Your concrete surfaces may sink or crack as voids open underneath the slab months after the winter is over.

If you notice any signs of concrete damage, contact an expert like the ones at Polyjacking.com. It is urgent that you begin concrete repairs as soon as possible. The longer you put off a repair, the more it will take to correct the problem and the more money it will cost. The slab won’t heal itself and, in the long run, the concrete will eventually fail, taking your driveway or patio with it. It is important to protect your property and your family or employees. You should make sure that you have the best concrete expert in the St. Louis area.

Concrete Repair Services in St. Louis

If you have cracks in your concrete or the slab is sinking or unlevel, it is important that you get it repaired before someone gets hurt or other problems begin to occur. We recommend using high-density polyurethane foam. This foam is injected under the slab and, as it expands, it fills the voids, seals the cracks, and lifts the concrete to the desired height. Polyjacking a slab is 75% less expensive than breaking up and replacing the damaged concrete.

We know that St. Louis businesses and homeowners don’t have time to wait to use their sidewalks or driveways, that’s why polyjacking is such a smart choice. It takes 80% less time to complete the repair and the slab can be used within 15 minutes of the foam being injected. Due to this quick turnaround time, traffic and pedestrians can quickly use the slab once again, safely.

The soil in the St. Louis area is mostly expansive clay, so it is constantly moving. The polyurethane foam expands, filling the void, which minimizes the chances of the soil failing again. The foam also seals off the bottom of the slab, eliminating the water from penetrating the concrete or eroding the slab.

How Do Voids Under Concrete Form?

When the ground under a concrete slab erodes, it can cause a lot of problems. Homes with basements usually have the most problems, but voids can impact driveways, patios, sidewalks, and more. The erosion causes air pockets or voids to develop under the concrete slab, taking support away from the surface.

filling voids under concrete

Causes of Voids

There are several different reasons that a void can occur beneath your concrete. Most of the time, it isn’t due to erosion, but other factors. Some issues can happen quickly, while others can take years to cause problems.

Soil consolidation occurs over time. This occurs when loose soil under the concrete consolidates or sifts down. If the soil is not properly prepared by being tamped down, this can occur. When the soil consolidates, a void can form over time.

Settlement is a natural occurrence that happens over time. It can occur with new construction or with a property that is a hundred years old. It all depends on the type of soil and weather patterns. Heavy rains or flooding can cause the soil to settle faster than normal. If the settling soil is in a large enough area, it can allow erosion to occur. Settling soil sets the table for a problem, erosion just makes it worse.

If water doesn’t drain correctly or there is new landscaping or other additions to the property, erosion can start after years with no problems. The water will run freely, washing out the soil and creating a void under the concrete. The bigger the void, the more damage that can occur.

Solutions for Voids Under Your Concrete

commercial polyjackingYou don’t have to tear up your concrete to fix the problem of having a void. The best solution is polyjacking. High-Density polyurethane foam is injected through small holes into the voids. The foam expands, filling the void and sealing any cracks on the underside of the slab. The foam will not wash away and the slab is usable shortly after the foam is injected. Mudjacking is an alternative, but the sand-based grout can be washed away or not fill the void and you’re back to square one.

You’ll still need to take care of drainage problems, as they will continue to cause problems for your home or business. Make sure that water is draining correctly and away from the foundation or concrete area. The polyurethane foam won’t wash away, but the surrounding soil can erode. Let a company like Pro Foundation Technology assist you with waterproofing services.

Protect your property from foundation damage, trip and fall hazards, and sunken concrete by making sure the water is draining from your property. If you already have problems, let an expert like those at Polyjacking.com help you restore your concrete slab to the necessary height.

Concrete Repair In The Winter

Ice and cracks are not a good combination. If you have cracks in your concrete, they can let water in and if that water freezes, the crack will grow bigger. As we all know, a Kansas City winter can be a nightmare!

Ice Can Be Destructive to Concrete

When water turns to ice, it can expand almost 10% more in volume than its liquid amount. This is a small number in the big scheme of things, but even a small change in a crack can cause a big problem. The pressure behind expanding ice is very strong. According to chemical engineer Geoffrey Widdison, freezing water can theoretically exert around 30,000 psi! That amount of force can easily destroy concrete foundations and slabs. The cracks can spread and grow wider, causing a wide variety of structural problems. The problems can happen when your property experiences its first freeze-thaw cycle, getting worse with every cycle.

As stated earlier, this can impact both foundations or concrete slabs. Once water enters the crack, your home or business could have water in the basement or crawl space or it could enter the foundation walls. Water can also cause concrete shrinkage and other structural damage.

concrete problems in the winter

Ice Can Cause Concrete Problems

As much as some of us would like to stop winter from coming, it comes just the same. The winter weather in Kansas City can damage your concrete slab, foundation walls, and any other concrete surface you may have at your home or business. The surface of the concrete can be a victim of “mortar flaking“. This occurs when the top layer of the concrete peels or flakes off.

As we stated above, any previous cracks can get bigger and longer and new cracks may form. Cracked concrete loses a lot of its strength and can lead to foundation failure or trip hazards on concrete slabs.

Yet another problem is something called “popout”. Popout occurs when the water behind or underneath a concrete surface swells, pushing against the concrete. It can cause flaking, crumbling, and cracking. This can occur at any time of the year, but it is more prevalent in the winter months.

Tips For Keeping Your Concrete Safe

The best thing you can do to protect your concrete is to keep water from freezing on it or next to it, but that’s pretty difficult. Make sure that your home or business is ready for the winter weather. Downspouts and gutters should be clear and drain well away from the foundation, at least 10 feet or more. Clear snow and ice from around the foundation; melting snow can run down the foundation walls and cause problems.

Polyjacking.com can help you keep your concrete stable and safe. With Pro Foundation Technology behind us, we can offer waterproofing, concrete lifting, and more. We’ll keep your home or business safe, dry, and comfortable.

Polyjacking vs New Concrete

 

polyjacking vs new concreteTrip and fall accidents are the #1 leading cause of injuries around the home, but should you replace your slab or have it lifted? Protecting your family, employees, and customers are all important, but you need to make an educated decision.

In the past, most people would just break up the old slab, level out the underlying soil and have new concrete poured in the same location. Today, polyjacking has become a much better option and has become more popular throughout the industry.

How Polyjacking Works

The polyjacking process is relatively simple and, though it doesn’t take long, it is extremely effective. The process uses little equipment, so you won’t have a bunch of trucks or other machines cluttering up your property. Small holes (5/8″) are drilled into the slab. The polyurethane foam is injected through the holes and expands under the slab, filling in voids, gaps, and cracks. The slab is raised to the required height and the foam seals the bottom of the slab, preventing more gaps and cracks from forming.

Once the slab is raised to the desired height, the holes are closed and the foam cures in about 15 minutes. Once the foam is hard, you can walk or drive on the slab, allowing everyone to get back to their normal day-to-day routine.

Benefits of Polyjacking vs New Concrete

We’ve told you about the process of polyjacking and some of the benefits, but what about replacing the slab with new concrete?

Some things to consider when thinking about new concrete:

  • Concrete replacement can cost twice as much or more than polyjacking
  • The new concrete is likely to have a different color than the existing slab
  • The cause of the sinking slab may not be repaired

With polyjacking, there is little disturbance to your lawn and landscaping, whereas heavy equipment is needed to break up the old concrete and remove it. After the slab is removed, a mixer is brought in to pour the new slab, adding to the machinery required. Polyjacking just uses one truck or trailer to raise the slab.

If you are debating whether to go with polyjacking or pouring a new slab, contact Polyjacking.com to go over your options. We’ll be honest with you and show you the pros and cons of each method.

Is Water Ponding on Your Drive or Patio?

puddle on concrete, water ponding, water poolingHave you noticed, especially after recent heavy rains, water ponding on your patio, driveway, or other concrete slabs? While there may be no visible cracks, somehow the concrete has settled or sunk, and water simply accumulates there, unable to run off. Besides being inconvenient and unsightly, it presents a safety hazard for your family and friends who walk across the concrete surface. The question is, “What should you do about it?

Causes of Water Ponding

If there is no obvious crack or hole in the concrete which allows water to seep onto its surface, water ponding often is caused by incorrect grading of the concrete slab from the time it was poured. It is critical that the concrete is set up with a slight slope away from the house and foundation so that the water has an opportunity to run off into the yard, drain, or drainage ditch. If not, water will simply remain pooled on top of the concrete.

Frequently, natural settlement of the soil through the passage of time will cause the concrete to sink in such a way that water is unable to run off. For that reason, builders often recommend not building concrete patios until the soil around a new construction has had adequate time to settle.

Most often, water ponding is due to changes in the soil beneath the concrete slab. After cycles of wet and dry or freezing and thawing, the soil beneath the concrete may become unstable and develop pockets or holes. Eventually, the soil will not be able to support the concrete, and the concrete will actually sink into the holes beneath it. Naturally, after a heavy rain, water will pool into the lowest sections of the concrete.

Three Choices for Solving Water Ponding

There are basically three choices regarding what to do to repair a concrete slab that has water ponding. You can grind it, replace it, or raise it. The following information explains the three options along with their advantages and disadvantages. Hopefully, it will help you determine the best option for your sinking concrete.

Grinding Concrete

Grinding involves milling off a portion of the good concrete slab so it matches the sunken slab. While it may eliminate a trip hazard, it does not solve the underlying problem and offers only a short-term solution.

The Truth about Grinding

While some companies are willing to grind off a layer of a good slab to fix a trip hazard, it doesn’t solve the underlying problem: what caused the slab to settle in the first place? Unfortunately, whatever caused the problem in the first place will simply return, usually within a year. If the company grinds the concrete a year later, the problem will simply occur the next year, and so on.

The bottom line is that grinding a good section of concrete never solves the root of the settling problem. It’s the underlying soil that caused the settling in the first place. After several years have gone by, the concrete will simply become too thin and crack, requiring the entire slab to be replaced. Besides paying for the annual grinding, the homeowner is now faced with the expensive option of replacing the concrete.

If you are extremely tight on funds, grinding could be a solution for you. Keep in mind that it is a short-term fix that eventually will require replacement of 2 or more concrete slabs.

Replacing Concrete

concrete leveling, concrete replacement, cost of concrete replacementReplacement involves tearing out the old concrete and building a new concrete slab in the same spot. It is very costly and disruptive and could lead to further problems in other parts of the structure.

The Truth about Concrete Replacement

Replacing a concrete slab is the most expensive method to eliminate a tripping hazard. Not only will you have the cost to tear out and remove the old concrete, but you will also need to pay for the grading, materials, and labor for the new slab.

Concrete replacement is also extremely disruptive. Besides creating loud noises with the jack-hammers, removing the old concrete creates a great deal of dust and mess. It also tears up the soil and landscaping surrounding the slab. Bringing in a cement truck to pour the concrete can also tear up the yard and make a mess. Also, it takes a long time for the concrete to cure before you can use it again.

Finally, concrete removal and replacement could damage other parts of the structure while the concrete slab is removed and the soil is disrupted. If they are not properly braced, adjacent decks, porches, crawl spaces, drainage systems, and the foundation itself could be damaged during the process, leading to an even greater expense.

Concrete Raising and Leveling

Concrete raising involves pumping either a concrete grout (mudjacking) or a polyurethane solution (polyjacking) through holes in the concrete slab to fill the voids underneath and raise the concrete.

The Truth about  Concrete Raising and Leveling

Mudjacking

Mudjacking lifts and raises concrete slabs by pumping sand-based grout beneath it. The force of the pump pushes the slab back into place. Unfortunately, it is very messy, takes a long time to dry, and isn’t a permanent solution because the conditions that caused the soil to shift under the slab still exist. It will only be a matter of time before the slab has slipped again.

polyjacking, concrete lifting, concrete levelingPolyjacking

Polyjacking, sometimes called foamjacking, lifts and levels slab foundations through injecting a high-density polyurethane foam beneath the slab through small holes drilled in the concrete. The foam expands and gently lifts the entire slab back into place.

Polyjacking has many advantages over mudjacking and other methods of concrete repair:

  • It requires drilling only small holes
  • The polyurethane solution is lighter than mud grout
  • Polyurethane expands to fill in the holes and voids and stabilize the soil
  • It takes much less time to apply and dry
  • Polyurethane lasts a long time
  • Polyurethane is waterproof and flexible during changes in the soil moisture or temperature
  • Injecting beneath the slab does not disrupt surrounding structures, soil, utilities, or landscaping
  • Poly foams are environmentally friendly, with up to 50% renewable and recycled materials
  • Poly foams can be customized to each type of soil and conditions.

Initially, polyjacking is more expensive than either grinding or mudjacking. In the long-run, however, it is more cost-effective because it is extremely long-lasting and will not need to be redone in a year or two. Also, polyjacking not only stabilizes the soil, but it also strengthens it, so that the concrete is far less likely to crack or need to be replaced.

Restoring a Historic Building’s Foundation

Historic Building Foundations

Reasons for Foundation Failure in Historic Buildings

historic building foundations, restoring historic foundations, foundation restorationHistoric buildings, like all structures, often develop problems with a foundation that is sinking or become unleveled over time. There is some special consideration to keep in mind in restoring historic building foundations. Older buildings are particularly prone to foundation failure for several reasons.

Unstable soils – After a period of time, soils beneath and surrounding a foundation may become more compacted, shift, or develop gaps. This may be caused by flooding, removal or addition of trees and landscaping features, or years of changing soil moisture and freezing/thawing patterns.

Improper water drainage – At times, historic buildings are built on old creek beds or new floodplains. Construction on adjacent properties or parking lots may have altered the flow of water toward the property. Over time, even weather patterns may require the installation of improved interior and exterior water drainage systems to prevent foundation damage.

Foundation materials – Many older foundations are built from bricks or stones with mortar that deteriorates over time or develops cracks allowing water to leak and damage the foundation.

Dirt floors – Often older foundations have dirt floors that are more likely to allow water to enter the basement and cause further damage to the foundation.

Signs of Foundation Failure at a Historic Property

Historic properties, like all buildings, often display classic signs of foundation failure:

  • Collapsed masonry walls
  • Sloping floors
  • Cracks in walls, floors, or ceilings
  • Misaligned doors and windows

Because historic buildings may be somewhat fragile and have historical value, you must hire a foundation contractor with an established record working on historic buildings.

Overall Guidelines for Restoring a Historic Building

Memorial Union, historic foundation leveling, Polyurethane Concrete LevelingWhenever a historic building requires restoration, there are certain standards which must be followed:

  • Retain Original Function – The property must be used in its original function or be given a new use which reflects its original period.
  • Retain Original Design and Features – Materials, features, spaces, and spatial relationships from the property’s period will be kept and preserved.
  • Retain Original Appearance – Work to stabilize and conserve the property will be physically and visually compatible with the restoration period and documented for future research.
  • Use Original Materials – Materials, features, and finishes characteristic from other historical periods will be documented before their alteration or removal.
  • Use Original Craftsmanship – Distinctive materials, features, finishes, construction techniques, and craftsmanship of the restoration period will be preserved.
  • Repair, Don’t Replace – Deteriorated features from the restoration period will be repaired rather than replaced. If a feature is replaced, it will match the old in design, color, texture, and, when possible, materials.
  • Document Changes – Replacement of missing features will be documented to preserve the original history of the property.
  • Prevent Damage to Materials – Chemical or physical treatments will be implemented in the gentlest means possible to prevent damage to historic materials.
  • Protect Archeological Resources – Archeological resources affected by a project will be protected and preserved in place with as little change as possible.
  • Protect Original Design – Designs that were never implemented during the restoration period will not be constructed.

 Considerations When Restoring a Historic Foundation

Below are some of the key steps you should undertake when hiring a contractor to repair or replace the foundation on your historic structure.

Hire a Structural Engineer – It’s always a good idea to hire a structural engineer who specializes in historic building foundations or has some experience with historic structures to determine how much of your foundation needs to be replaced. A structural engineer will determine the underlying issues and the best solution to repair the foundation and resolve the problem.

Document the Details – Before doing foundation repair or any restoration on a historic building, it is important to document as many details as possible. Take pictures, do measurements, and write down details of everything you observe. This will ensure that the new foundation will look exactly like the old one.

Hire an Experience Foundation Contractor – Especially with a historic property, it is essential to hire an experienced foundation contractor to restore the foundation. They will know and follow the restoration guidelines and will make certain that you have the necessary insurance and permit. Because of their experience, they will know historic materials and techniques and take extra precautions so that none of the structure collapses or experiences further damage. Polyjacking.com has been a family-owned and operated business since 1978 and has an outstanding reputation in restoring foundations of both residential and commercial structures, including historic ones.

Choose Matching Materials – Often older structures will have a brick or stone foundation, so you want to salvage as many of the original bricks or stones as possible. Even if you replace the original foundation with a concrete one, you can do masonry on the outside to make the new foundation look like the original.

Waterproof the New Basement – As long as you are replacing the foundation, you might want a contractor to place drainage tiles along the perimeter of the foundation to waterproof the basement. Polyjacking.com’s parent company, Pro Foundation Technology does basement waterproofing.

Consider Related Projects – If you have an old staircase in the basement that cannot be used, hire someone to build a new one. It’s also a good time to check and replace any outdated electrical, plumbing, or drainage systems. Replacing the soil around the foundation with a quality black topsoil and grading it to a five-degree angle away from the foundation will provide good exterior drainage.

Polyjacking Restores Historic Belle Meade Plantation

Built inBelle Meade Plantation, sinking foundation, sloping floors 1807 by John Harding, the historic Belle Meade Plantation developed into a 400-acre thoroughbred horse farm with its own train station, horse park, Greek-revival mansion, and housing for servants and former slaves. Today, Belle Meade Plantation includes 34 acres of its original property and several buildings, including the mansion and several outbuildings. It functions now as an educational resource dedicated to preserving Tennessee’s Victorian architecture, history, and equestrian lifestyle. Visitors can tour the buildings, shop, dine, taste wine, and enjoy special events held at this historic plantation. See their website at http://bellemeadeplantation.com/.

Belle Meade Mansion

The Belle Meade Plantation mansion began as a two-story Federal-style home, built in the 1820s with red bricks on a limestone foundation. On each side was a one-story wing. In the 1840s, William Giles Harding made additions to the original home and updated the style to Greek-Revival. The mansion features three floors with ceiling heights of fourteen feet on the lower two floors and eight feet on the top floor. It also contains a central hallway that extends through the three levels and a circular, cantilevered staircase with empire style spirals carved from cherry wood. Throughout the home are palladium wall niches for holding lamps at night. The home contains bedrooms for family members and guests as well as servants’ quarters.

Foundation Problems at Belle Meade Mansion

foundation repair, concrete leveling, sinking floorThe limestone foundation at Belle Meade Mansion was having issues common with many older homes. It was sinking into the soil beneath it. After many years, rainwater had caused hydrostatic (water) pressure, creating cracks and water seepage in the walls and floor of the foundation. Heavy rains also caused water to seep beneath the foundation, and continued freezing and thawing had caused the soil to expand and contract, creating sinking and voids in the ground beneath the structure.

Because of the sinking and leaning walls in the foundation, it could no longer provide adequate support to the structure about it. Signs of foundation failure included sloping and uneven floors in many rooms of the old mansion. Because of the age and historic value of the building, the preservers of the property knew they couldn’t hire just anyone to restore the 200-year-old foundation without damaging the above structure.

Polyjacking Restores the Mansion’s Sinking Foundation

Belles Meade Mansion, foundation repair TN, old building repairBecause of their reputation for doing outstanding foundation repair, including work on prior historic buildings, the management of Belle Meade Plantation did not hesitate to contact Pro Foundation Technology (PFT) and their division, Polyjacking.com, from Kansas City. PFT and Polyjacking.com have more than 30 years of experience doing waterproofing, concrete, and foundation repair in Kansas City and throughout the Kansas and Missouri area. They use the highest-quality products from US manufacturer, Earth Contact Products (ECP) and have won recent recognition from HomeAdvisor for their quality service and workmanship.

Polyjacking.com made three trips to the historic mansion and were able to lift the sinking foundation and repair the underlying structure through the following steps:

  • Using ground penetrating radar to detect voids, holes, underground structures, utilities, and other objects beneath the foundation
  • Drilling small holes in the foundation floor in preparation for polyjacking
  • Filling the voids beneath the foundation with polyurethane foam that expands into the voids and stabilizes the soil beneath the foundation

Not only were they able to lift and level the foundation without messy external excavation, but they also caused minimal disruption to the operations at the plantation and caused no additional damage to the structure or its contents. Belle Meade Mansion is restored to its former glory, is supported by a stronger foundation, is more structurally sound than ever, and will last for many years to come.
