When the ground under a concrete slab erodes away, 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.
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 processes are fast, 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 property that is a hundred years old. It all depends on the type of soil and the 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 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 create a void under the concrete. The bigger the void, the more damage that can occur.
Solutions for Voids Under Your Concrete
You don’t have to tear up your concrete to fix the problem of having a void. The best solution is polyjacking. A 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 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.
Trip 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 spot. 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 (3/8″ to 1/2″ inches) 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 you to get back to normal.
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 grass 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.

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. Throughout the home are palladium wall niches for holding lamps at night. The home contains bedrooms for family members and guests as well as servant’s quarters.
Foundation Problems at Belle Meade Mansion
The limestone foundation at Belle Meade was having issues common at 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 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 Kansas and Missouri. 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, they 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, and will last for many years to come.

Polyjacking Helps Anadarkio Petroleum
Anadarkio 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, 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’s parent company, shares:
“It’s [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 Polyuethanes, a Fort Worth, TX company. Polyjacking.com installs the polyurethane via the following procedure:
- Using radar equipment to find voids in the soil
- Drilling small 5/8 inch holes into the concrete
- Using hoses to inject the TerraThane polymer
- Applying the right amount for lifting and leveling the concrete
- Doing 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 create 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 Anadarkio Petroleum hydraulic fracturing station, one of six located on the Wattenberg Gas Field, which is considered the ninth largest gas reserve in the entire US.

The Importance of Foamjacking in Kansas City
Groundwater, erosion and soil decomposition can cause your foundation to break down and settle. If you notice your sidewalks, driveways, walkways, patios are in need of leveling, foamjacking is one of the best ways of achieving this. The life of your concrete structure is extended at a fraction of the cost of replacing these structures.
Foamjacking, also called polyjacking, is an economical repair process for fixing settled and unstable concrete. From small projects to big projects, foamjacking is economical, fast and effective for correcting these settlement and instability issues.
Foamjacking uses a polyurethane foam that is injected under the slab and this foam expands immediately filling any voids under the surface of the slab, raising it back to a level position. A small 5/8” hole is drilled and special equipment is used to inject the high-density polyurethane. This is a cleaner process than most concrete leveling systems. The injection equipment is directly connected to the slab or structure and the seals engage when not injecting the material, so nothing spills onto the area. The drilling is mess-free due to the small size of the hole that is drilled. Polyurethane is also environmentally safe.
Because it is the quietest and fastest process for concrete leveling, foamjacking is less disruptive. Vehicle and foot traffic can resume immediately after work is completed. Polyurethane is a lightweight material, only adding 3-5 pounds per cubic foot to the sub base, therefore, it reduces the chances of resettlement of the underlying soils. Foamjacking, using this high-density polyurethane is waterproof, so the treated area is thoroughly undersealed.
Foamjacking is a good solution for:
- Large, heavy slabs
- Areas where cleanliness is important
- Sensitive or expensive surfaces
- Load sensitive areas
- Isolated sites
- Pavement Lifting/Leveling/Undersealing
- Soil Stabilization
- Infrastructure Repair
- Void Filling
- Road leveling
- Airport Runway Leveling
- Sidewalk Leveling
- Abandoned Sewer Line Void Filling
- Warehouse Floor Leveling
- Manhole Leak Repair
- Curb Leveling
