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.

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.

Concrete Leveling at Denver Gas Company

Polyjacking Helps Anadarko Petroleum

Natural Gas Field, concrete leveling, polyjackingAnadarko Petroleum operates six hydraulic fracturing stations on the Wattenberg Gas Field located beneath the states of Colorado and Wyoming. When an inlet pipe broke recently at its station just north of Denver, CO, injection fluid drained beneath the concrete slab at the station. This caused 3- to 5-inch voids to form under the concrete floor which left the concrete floor unlevel. The general contractor of their onsite service company, Open Range Services (ORS), knew he needed to find an efficient and effective solution for lifting and leveling the sinking concrete slab.

Why Mudjacking Wasn’t a Good Option

At first, the head of Open Range Services considered using the “tried and true” method of concrete leveling, mudjacking. Mudjacking forces a mixture of concrete and other aggregates beneath concrete slabs in order to lift and level them. After some consideration, he found that mudjacking would not only be too expensive, but that it would take a lot longer to apply. In addition, ORS would have the added cost of removing and replacing the entire slab instead of simply repairing it.

Why Polyjacking Is Best for Concrete Leveling

When ORS contacted Polyjacking.com about their concrete leveling process, it soon became clear that polyjacking was a superior solution for their situation. Steve Walker, general foreman for Pro Foundation Technology, Polyjacking.com’s parent company, shares:

“[Polyjacking is] a far superior method. Mudjacking means you drill large holes in the slab, mix the mud or grout onsite, and pump it using large hoses into the holes in the slab. It’s dirty, invasive, and time-consuming. Geotechnical polyurethane foam is much lighter- four pounds per cubic yard, versus 120 pounds or more using mud – simpler, cleaner to use, and much less expensive. We pump a two-part liquid system from a truck or pull-behind rig through a narrow hose into a gun used to inject the unique geotechnical foam beneath the slab to fill any and all voids. The foam expands, completely fills the empty space, raises the slab to level, then cures in place to become highly durable and [help] prevent further erosion at that site.”

Polyjacking is Easier and Faster to Install

Polyjacking.com uses a compound called TerraThane to inject beneath concrete slabs for lifting and leveling. TerraThane is manufactured by NCFI Polyurethanes, a Fort Worth, TX company. Polyjacking.com installs the polyurethane foam via the following procedure:

  • Using radar equipment, find voids in the soil
  • Drill small 5/8 inch holes into the concrete
  • Use hoses to inject the TerraThane polymer
  • Apply the right amount for lifting and leveling the concrete
  • Complete appropriate clean-up (which is always minimal)

The complete process usually takes less than seven hours. Mudjacking, on the other hand, may require weeks or months to complete and creates a huge mess. For additional information on mudjacking vs. polyjacking, click here.

Open Range Services is Pleased with the Results

According to Steve Walker, Open Range Services was very satisfied with the final results, “They said they knew who to call if it happened again.” Things are running smoothly again at this particular Anadarko Petroleum hydraulic fracturing station, one of six located on the Wattenberg Gas Field, which is considered the ninth largest gas reserve in the entire United States.

Out With the Old (Mudjacking) & In With the New (Polyjacking)

polyjacking and old mudjacking for Kansas City and St. Louis locationsWhat is mudjacking? Mudjacking is a concrete repair method used to lift and level sunken concrete. Since the 1900s, many businesses and homes have benefitted from mudjacking. It has been used to stabilize basement floors, driveways, sidewalks, patios, garage floors, and more. Mudjacking has been used for decades, so there are no surprises when you use this method. You know exactly what you are getting, for better or for worse.

In some cases, mudjacking can be a temporary solution due to its inability to resist moisture. As a result, the slurry may break down, wash away, and weaken. Because of these drawbacks, polyjacking has gained popularity over the years. If you have sunken concrete, we recommend polyjacking so you can save money and time in Missouri, Kansas, and the surrounding area.

Benefits of Polyjacking vs Mudjacking

new polyjacking concrete leveling for St. Louis and Kansas CitySo what makes polyjacking better than mudjacking? There are numerous reasons for using polyjacking over mudjacking.

Material and Drill Holes

Aside from not being moisture resistant, mudjacking uses a heavy cement-based mixture that weighs nearly 100 lbs per cubic foot. Many large holes are drilled through the slab so the material can pass through the slab, fill in the voids, and lift the slab back in place.

With polyjacking, polyurethane is used to lift and level sunken concrete to its desired height. Polyurethane weighs about 2 lbs, requiring fewer and smaller drill holes for the injection process. Within a few seconds, a chemical reaction occurs and polyurethane turns into foam. The foam expands and fills in voids under the slab.

Curing Process

Mudjacking can take 1-2 days to complete as opposed to polyurethane foam which cures within 15 minutes.

Long Term vs Short Term Repair

Since polyurethane foam is lightweight, it won’t burden loose or weak soil under the slab. This prevents future settling, making it a long-term repair solution. On the other hand, mudjacking is a short-term repair method because it uses thick material that overburdens loose soils.

Patched Holes

Since mudjacking requires many large holes, more patchwork is needed. Mudjacking patched holes are more noticeable and less attractive than polyjacking’s patched holes.

Both mudjacking and polyjacking achieve the same results when lifting and leveling sunken concrete, but polyjacking has become a preferred method over traditional mudjacking. At Polyjacking.com, we offer polyjacking to permanently restore your settling sidewalk, driveway, patio, pool deck, and more. Contact us today for more information or an estimate.

Mudjacking vs. Foam – Best Practices for Concrete Leveling

There are a few slab jack methods to choose from when it comes to concrete leveling. Whether it’s mudjacking or foam injections, both are designed to lift and stabilize the slab. However, there are subtle differences. It’s essential to know the differences, so you can decide the best option for your concrete leveling project.

Mudjacking

Men mudjacking a concrete slab to lift itMudjacking is the oldest concrete lifting and leveling process. The installation process uses grout to lift the concrete back to its original state. The grout is comprised of heavy sand-based material. First, a large 2-3″ hole is drilled through the slab, then the grout is pumped under the concrete to raise it back in place.

Unlike polyurethane foam injections or polyjacking, mudjacking has several drawbacks such as:

  • Uses heavy grout material, causing foundation damage and settlement over time
  • Requires numerous large drilled holes to lift the concrete
  • The material may deteriorate, erode, or crack, creating instability
  • Takes 24 hours to completely cure
  • Messy material and worksite
  • Does not stabilize the underlying soils due to the thickness of the grout material

Polyurethane Foam Injections

Polyurethane foam injections are a newer concrete leveling method used to lift settling and sinking concrete. In the past, it was mainly used for public work applications for highways and streets. Now, it involves residential and commercial projects, as well.

Unlike mudjacking, foam injections use dense material that weighs 2 lbs per cubic foot. A 5/8 diameter hole is drilled through the concrete, then polyurethane is injected under the slab and into the ground.

As the foam is injected, it expands and fills in voids and gaps. Also, the foam lifts the concrete back to its original position, preventing future settlement.

The polyurethane foam is water-resistant, so it won’t wash away and the foam seals the bottom of the slab, preventing water damage from impacting the concrete.

Mudjacking vs. Foam – Benefits of Foam Injections

Although foam injection is a newer concrete leveling process, it offers many benefits. Some of these benefits include:

  • drilling holes in concrete to implement polyjackingFewer and smaller drilled holes than other methods
  • Dense, lightweight foam
  • Cures within 15 minutes
  • Moisture-resistant
  • Strengthens weak soils
  • Fills voids and holes
  • Long-term repair
  • Eco-friendly material
  • More accurate than other methods (within 10/1000th of an inch)

These are a few advantages of polyurethane foam injections used to lift your settling concrete slab. At Polyjacking.com, we can help you determine the best concrete leveling and lifting method for your slab.

Both methods, polyjacking and mudjacking, are designed to strengthen and stabilize your concrete surface for many years to come. Contact Polyjacking.com for more information about foam vs. mudjacking.

Extreme Weather and the Effect On Your Concrete

Extreme Weather 

Extreme weather and concrete repair in the St. Louis and Kansas City areaResidents in Kansas City and the surrounding area are used to snowy and icy winters. But what is different in the past few years is the extent and number of icy, snowy storms that this area has endured. These long, extended periods of ice and snow will affect your concrete and in the spring, you may see the damage that the harsh winter has caused.

When water freezes, it expands, and, adding the constant freeze-thaw cycles with a lot of moisture, the potential for concrete damage increases. One of the effects that cause extreme weather conditions is D-cracking. D-cracks are closely spaced cracks along the joints of the concrete.

If you find concrete damage in the spring after the extreme weather of the winter months, contact Polyjacking.com. We have the products and experience to get your concrete repaired in Kansas City, MO.

Concrete Repair Solutions

What Causes Voids in Kansas City and St. Louis?

Void & Concrete Repair

cause of voids in St. Louis and Kansas CityMost people think concrete repair is needed for mature, existing concrete structures caused by outside elements. However, concrete repair can also be needed for newer construction. If concrete is so widely used in the construction industry, why does it sometimes form voids under the surface and deteriorate so quickly? Unfortunately, this may be due to environmental causes or human error. Some environmental causes are problems created by:

  • Freezing and thawing conditions
  • Drought-like weather conditions
  • Chemical agents such as salts and moisture
  • Decaying organic materials
  • Shrink and swell cycles (excessive water)
  • Soil erosion
  • Hydrostatic pressure

Voids can also be caused by human error due to poorly compacted fill material, too much water added to concrete, inadequate concrete cover or structural overload. These conditions can weaken the concrete surface causing settlement, sinking, and shifting over time. The concrete may start to crumble, crack, flake, or chip.

What Can Be Polyjacked?

Polyjacking Concrete Repair in St. Louis and Kansas CityWhat 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, but 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?

Polyjacking offers the following benefits:

  • Durability
  • Maintains structural integrity
  • Moisture seal barrier
  • Fast curing time
  • No demolition or excavation
  • Drills smaller holes
  • Less noticeable
  • Contours to the shape and size of the voids
