Category Archives: Foundation Repair
Concrete surfaces such as basement floors, driveways, patios, and more are all impacted by soil movement and weather that can cause damage and weakness. The slabs can also sink if the surrounding soil no longer supports it. These problems won’t repair themselves, the longer you wait to fix the problem, the bigger the issue and damage will be.
If your foundation sinks, it can cause damage throughout your business or home. Walls and floors can crack or lean, floors can slope or warp, and doors and windows may not stay open or closed. The worst case scenario is that the foundation collapses and brings your structure down with it. If the soil that supports the foundation or concrete becomes oversaturated, too dry, or isn’t compressed correctly, it will no longer give the slab the stability that it needs.
Luckily, there are solutions to keep your concrete and foundation stable and level.
Polyjacking and Mudjacking Solutions
Sinking concrete usually occurs because a void has formed under the slab. Unless the void is filled and the soil stabilized, the concrete will continue to sink. If left unaddressed, the repair may have to be done with underpinning, greatly raising the time, money, and effort needed to fix the problem.
When it comes to the task of filling in voids, mudjacking and polyjacking both are up for the job. Mudjacking uses a mud slurry to fill the void and lift the concrete, whereas polyjacking utilizes a polyurethane foam to fill the void. In both methods, holes are drilled into the concrete above the void and then the slurry or foam is injected, filling the cavities below the concrete. The slab will be lifted to a level plane and the drilled holes will be filled. Mudjacking uses bigger holes than polyjacking (3-4″ compared to 3/4 to 1″).
Both forms of concrete lifting can be used for a variety of concrete surfaces including foundations, sidewalks, warehouse floors, tennis courts, and swimming pools.
Pros and Cons of Both Concrete Lifting Solutions
Though both methods are similar at face value, there are some pretty big differences between mudjacking and polyjacking.
- Comparatively inexpensive
- Naturally occurring materials
- Doesn’t fill the void completely
- Short-term results that have to be repeated every couple of years
- Slurry material is 30-50x heavier than polyurethane
- Slurry material is prone to erosion
- Large holes must be made in the concrete
- The slurry can take days to set and harden
- Long-lasting results
- Lightweight materials
- Polyurethane foam density completely fills the voids
- Soil mixes with the foam to bond securely and gains strength
- Small injection hole
- Doesn’t wash away
- Able to adjust leveling to within 1/100″
- Polyurethane foam sets within 15 minutes
- Costs more than mudjacking
- Not as well known

ECP Piers for Foundation Repairs
ECP is one of the largest manufacturers of piers for foundation repairs. They produce basically two types of piers: steel push piers and helical piers. Both kinds of piers are driven into the ground and anchored to your structure in order to lift and stabilize the building. Because both the products and installation are the highest quality, this type of repair is permanent, you won’t need to call us back in a year to redo the work on your home’s foundation.
Push piers are hydraulically driven through ECP’s patented steel brackets until they reach load-bearing rocks or soil. They have an unlimited structure lifting capability that can be installed with portable equipment so that we won’t need to bring in heavy machinery or destroy your lawn and landscaping. Polyjacking.com can install these push piers any time of year so that we have the ability to respond quickly as soon as you need to do the repair. Another advantage of push piers is that they can be installed from either the inside or outside the structure, depending on the circumstances.
Like push piers, ECP’s helical piers are hydraulically installed and anchored to a steel bracket. Unlike push piers, helical piers are screwed into the ground while the plates pull the support rod into the ground. Before work is begun, installers will predetermine the torque required to support the weight of the structure. Helical piers are ideal for lighter weight applications, such as decks and porches. They are also very quick and easy to install.

Historic Building Foundations
Reasons for Foundation Failure in Historic Buildings
Historic 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 a number of 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 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, it is particularly important that you hire a foundation contractor with an established record working on historic buildings.
Overall Guidelines for Restoring a Historic Building
Whenever 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 prior to 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 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 have knowledge of 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.

Built in 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 1840’s, 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
The 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
Because 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.

Top 8 Warning Signs of Foundation Problems
It is very common for homes to develop foundation issues at some point in their life. Right after construction, all homes have some degree of natural settling. Eventually, water leaks, changes in soil, hydrostatic pressure, and many other factors contribute to foundation problems. Following is a list of the top 8 warning signs that a home or business has foundation problems. Contact Polyjacking.com if you see any of these warning signs.
If the basement floor is wet or the basement walls are leaking water, it is important to address the cracks. Sometimes these leaks are a sign of more serious problems to the foundation of the structure. Over time, the soil beneath the foundation may settle and cause the foundation itself to sink or shift. Too much change may lead to severe cracks, water damage, and foundation failure.
Uneven or Sloping Floors
If the floors in the basement or inside the building are uneven, it is a sure sign there are foundation problems. It is likely that some portion of the foundation floor has sunk deeper into the soil or that a foundation wall is leaning or bowing. These are both serious issues that require foundation repair.
Cracks in Floors
It is not uncommon for floors to develop small cracks shortly after construction due to natural settling. Cracks which continue to expand or leak water should be addressed as soon as possible. Some cracks can be filled before they develop too much water damage. If cracks are due to shifting of the soil underneath the foundation, the concrete slab may require additional lifting or leveling.
Cracks in Walls or Ceilings
Most buildings will develop small cracks in the walls after construction due to natural settling. If cracks continue to become larger or leak, they should be filled before further problems develop. If cracks are horizontal, stair-stepping, or widening quickly, it may be a sign that the foundation needs to be repaired or replaced.
Bowing or Bulging Walls
Some soils, especially clay soils, have a tendency to expand and contract depending upon moisture content. If foundation walls are leaning, bowing or bulging, that is a sure sign that there is too much hydrostatic pressure from the exterior soil. This is a certain sign that the foundation needs some sort of reinforcement before it fails.
Sticky Doors and Windows
When doors and windows don’t open or close properly, it is usually due to a shift in the frame and surrounding wall or floor. Usually, you will find that there are cracks in the caulking area around the frame that may get wider or spread. This is a certain sign that the foundation is settling or sinking unevenly and should be repaired before it gets worse.
Gaps in Doors, Windows and Garage Doors
Gaps around doors, windows, and garage doors also indicate foundation issues. They are caused when the foundation floor begins to sink or become uneven or when the walls themselves begin to lean or rotate. Besides the fact that you don’t want cold or hot air leaking through gaps, it is an indicator that the foundation should be checked and repaired.
When your outside chimney is leaning, that is a certain sign of a foundation problem. Most likely the soil beneath the chimney is not supporting the chimney uniformly causing it to lean. This indicates that the foundation beneath the chimney needs additional support or repair.
What if you have warning signs?
If you have one or more of the above warning signs of foundation problems, it is important that you contact a foundation repair specialist immediately. Many of these problems are caused by a settling or sinking foundation. Polyjacking.com is the area specialist in lifting and leveling concrete foundations.

What is Polyjacking and Why is it Beneficial?
At Polyjacking.com, we use poly equipment and trucks to lift the concrete slab. Polyjacking is a process that requires raising the concrete slab by drilling holes through the top surface of the affected slab, then injecting high-density polyurethane foam into the holes to fill in voids and cracks.
There are many reasons why polyurethane is used as an alternative concrete repair method, but here are the most common reasons:
- Smaller holes: With polyurethane foam, we can drill smaller holes (5/8″) into the concrete than other methods. Mudjacking requires larger holes (2-3″).
- Lightweight material: Since polyurethane foam is lightweight compared to the mudjacking slurry, it doesn’t create pressure to underlying soils. The slurry used for mudjacking is heavy, causing resettlement over time.
- Fewer holes: Polyurethane foam requires fewer holes which makes your concrete surface look cleaner afterward compared to traditional mudjacking.
- Permanent repair: Polyjacking is a long-lasting repair method, not a temporary fix. It won’t lose density or erode like mudjacking. It cures within minutes, allowing you to use the concrete surface shortly after installation.
What Causes Concrete Settlement?
Polyjacking can be applied to sunken or settling concrete that needs to be realigned to its original position. The most common causes of settling concrete are due to the following soil-related issues:
- Poor drainage
- Soil erosion
- Soil compaction
- Plumbing leaks
- Soil shrinkage
What Kind of Concrete Surfaces may Require Polyjacking?
Polyjacking can be applied to sidewalks, driveways, walkways, parking lots, patios, steps, garage floors, and basement floors.
Not only do we offer residential repair service, we also provide commercial and industrial service to repair office floors, warehouses, sports arenas, libraries, and much more.
Why Choose Polyjacking Over Other Concrete Repair Methods?

Seasonal Polyjacking Issues in Kansas City, Missouri
Polyjacking is an important concrete repair service for many residents of Kansas City and St. Louis, MO. This service is used to lift and stabilize sinking concrete slabs. Sinking slabs are usually due to variations in temperatures and moisture content in the soil around the slab. Polyjacking is the most effective way to fix this issue, as it supports the foundation from underneath while compacting and stabilizing the soil. This results in a more stable foundation or slab and also helps to seal cracks in the concrete. Polyjacking.com, the Polyjacking branch of Pro Foundation Technology (PFT), can help restore your settling concrete slab immediately.
Settling concrete slabs are usually the result of voids and spaces forming beneath the slab. This can happen when the soil shrinks due to extremely dry, hot weather, or when frost in the ground freezes and thaws. Hydrostatic pressure is caused by excessive moisture absorbed by the soil. It pushes against the slab, causing it to shift and crack. Varying moisture content in the soil also leads to the formation of gaps and spaces in the soil under the foundation. These gaps cannot provide the adequate support for the concrete, causing the slab to sink and settle into these voids as a result. By using polyjacking to fill these voids, we can raise the slab to the proper position.
Cold temperatures can cause the foundation to heave and settle, requiring support from slab jacking underneath. Dry conditions can lead to soil shrinkage, forming voids that must be filled by polyjacking services. Whatever the seasonal issue is in your home, we can help give you the necessary repairs to ensure that your slab is well stabilized and protected from seasonal damage.
Polyjacking Services for Seasonal Repair in Kansas City
The polyjacking process consists of several essential steps. Poly equipment and trucks are used for the installation process. These steps in the process include:
- First, holes are drilled through the slab in a strategic pattern to maximize lift and minimize loss of structural integrity.
- Next, the high-density polyurethane foam is injected through the slabs to fill voids under the concrete.
- This polyurethane material expands to fill voids and compact the soil around the voids, creating a more stable foundation for the concrete slab.
- Once the slab is raised, any remaining cracks can be filled, as well as the holes that were drilled previously.
- The equipment is removed from the job site and the slab is back to normal and ready for regular use.
This polyjacking procedure can prevent seasonal foundation problems in your home or commercial structure. Polyjacking is a versatile service that can be used in nearly any type of weather to prevent all sorts of seasonal issues. Contact us today for more information.
Industrial Polyjacking in St. Louis, Kansas City, & More
Polyjacking is a permanent solution for settling industrial concrete floors. This method of concrete repair in the industrial setting injects polyurethane foam into a 5/8″ hole that is drilled through the damaged concrete. This polyurethane foam fills the voids beneath the concrete and lifts it back to its original level. Because of the quick drying time, the concrete is ready for use in about 15 minutes.
Concrete can move and shift due to the changing soil moisture beneath it. When the soil gets too wet, it tends to heave and when it is too dry, it shrinks. This shifting and shrinking of the soil cause voids beneath the concrete. This causes the concrete to settle into these voids. Polyurethane foam injected into these voids lifts and stabilizes the concrete back to its original level.
When an industry relies on production for their profit, you don’t want to have any downtime. That is why when there is a need for concrete repair, the best choice is polyjacking. There won’t be a long stretch of downtime and your concrete will be ready for use right after repairs are made. The curing time of the polyurethane foam is around 15 minutes.
Polyjacking is less expensive and much faster than concrete replacement. It has a lifting capability of 900 tons so the process can be completed without having to move machinery or shelving before the repairs begin.
Why Polyjacking for Industrial Concrete Repair?
Polyurethane foam has a compressive strength of 500 psi so it can hold up to the weight of industrial machinery, forklifts, warehouse shelving, and inventory. The other advantages of polyjacking and polyurethane foam are:
- Cleaner, mess-free application
- Less disruptive, fast process
- Ready for immediate traffic
- Lightweight material
The process of polyjacking allows for precise control of the lifting process to within 1/10th of an inch. There is no shrinkage of the material over time. Once the machinery, work tables, and shelving are leveled, they will stay that way for years to come. Some of the structures that benefit from polyjacking are apartment buildings, shopping malls, sports arenas, concert halls, skyscrapers, theatres, airports, factories, and amphitheaters.
If your industry facility is in need of concrete repair, let the experts at Polyjacking.com give you a free inspection.
The theatres in Kansas City and St. Louis are some of the largest and beautiful in the entire country. Keeping them well maintained is important. Part of the maintenance and upkeep of these theatres is concrete repair. Theatres are heavily used by the public and need to be in good repair to keep them safe and to protect equipment and furniture from being damaged.
Concrete floors can sink and crack due to the soil beneath them. When the soil constantly shifts and moves due to the changing moisture content, this creates voids beneath the concrete making the concrete sink into the voids. Repairing concrete before it totally fails is important. If you see sinking concrete theatre floors in Kansas City, we offer polyjacking to level concrete back to its original level.
Polyjacking Used for Theatre Concrete Floors
Polyjacking is relatively quick and efficient with the right poly equipment and products. The installation process includes drilling a 5/8 ” hole through the affected concrete then injecting the polyurethane foam into the hole. The foam will expand to completely fill the voids beneath the concrete. As the voids are filled, the concrete is lifted back to its original level. The foam hardens within 15 minutes and then the concrete is ready for use. After the foam injection is completed, the holes are filled and the site is cleaned up. All polyurethane trucks and equipment are removed.
There are many advantages to using the polyjacking process for theatre projects. Some of these include:
- Economical – Much less costly than removing and replacing concrete
- Moisture resistant – Polyurethane foam guards against moisture
- Less disruption – Polyurethane foam dries quickly so concert hall can be used immediately
- Accurate – The foam creates a precise hydraulic lift
- Durability – Polyurethane foam is strong yet dense and can support a large amount of weight
- Conformability – Polyurethane foam contours to the size and shape of the voids to provide total coverage
To accurately locate the voids beneath the concrete, we use a ground penetrating radar (GPR). Using a GPR is a fraction of the cost of the X-ray method and there is no exposure to radiation. The GPR units are portable and provide an instant location. This reduces the time spent on-site and gets the theatre concrete repair done more quickly.
Don’t let damaged concrete in your St. Louis or Kansas City theatre cause you to close the venue for an extended period of time. We can be in and out in hours, not days. Polyjacking.com has the experience to ensure that your concrete repair is done right the first time and will last for years to come. Don’t hesitate to contact us if you are in need of theatre concrete repair in St. Louis and Kansas City.
