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.
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.
Have you noticed, especially after recent heavy rains, water ponding on your patio, driveway, or other concrete slabs? While there may be no cracks, somehow the concrete has settled or sunk, and water simply accumulates there, unable to run off. Besides being inconvenient and unsightly, it present a safety hazard for your family and friends who walk across the concrete surface. The quetions 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 article explains the three options along with their advantages and disadvantages. Hopefully, it will help you determine the best option for your sinking concrete.
Grinding involves grinding 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. Its 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 tights 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.
Replacement 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, you will need to pay for the grading, materials, and labor for the new slab.
Concrete replacement is also extremely disruptive. Besides creating loud noise 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 also tears up the yard and makes 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 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 even greater expense.
Concrete Raising and Leveling
Concrete raising involves pumping either a concrete grout (mudjacking) or a polyurethane solution (polyjacking) through small holes in the concrete slab to fill the voids underneath and raise the concrete.
The Truth about Concrete Raising and Leveling
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.
Poly Jacking, sometimes called Foam jacking, lifts and levels slab foundations through injecting 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 last 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, it strengthens it, so that the concrete is far less likely to crack or need to be replaced.

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.

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 your home or a home you are about to purchase has foundation problems. Contact Polyjacking.com if you see any of these warning signs.
If your basement floor is wet or your basement walls are leaking water, it is important to address the cracks. Sometimes these leaks are a sign of more serious problems to your homes foundation. Over time, the soil beneath your 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 your basement or inside your home are uneven, it is a sure sign you have 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 address as soon as possible. Some cracks can be filled before they develop too much water damage. If cracks are due to shifting the soil underneath the foundation, the concrete slab may require additional lifting or leveling.
Cracks in Walls or Ceilings
Most homes 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 of 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 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 is 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 8 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.

Signs of Home and Foundation Damage
As a homeowner in Kansas or Missouri, it is critical to the life of your home that you regularly inspect your home and foundation. Damage to your home’s structure or foundation can appear at any time of the year, but Spring is when signs are most noticeable. In case you’re not sure what to look for, try following this Spring Home and Foundation Repair Checklist.
Spring Home and Foundation Repair Checklist
- Plumbing damage – Moisture is the biggest threat to the stability of your foundation. It’s a good idea for you or a plumbing professional to inspect your plumbing system for leaky or loose fitting pipes to make sure that there is no excess moisture damaging your foundation.
- Foundation damage – Look at the foundation itself. Have there been any changes? Are there signs of shifting, cracking or discoloration? If anything doesn’t seem right, call a foundation repair professional to inspect it for you.
- Cracked floors or walls – Take a tour of the rooms in your home and looked for new or widening cracks in the floors or walls. These are visual signs that your foundation may be shifting.
- Roof leaks – Hire a roofing contractor to regularly inspect your roof for leaks or other conditions that may trap or release any excess moisture into your structure.
- Mustiness or bugs in the basement – Inspect your basement. If there are bugs or a musty smell in your basement, these could indicate a moisture problem or foundation damage. Insects, including termites and earwigs, thrive in a moist environment.

Poor Yard Drainage
Sometimes yards, driveways and sidewalks in Kansas and Missouri can be flooded during March and April. Melting snow and springtime rains can lead to excess water and slow runoff. Poor yard drainage may cause many problems in your lawn, gardens, external concrete walkways and foundation, including:
- Mud in your lawn where children and pets cannot play
- Potential lawn problems due to insects and fungus
- Poor soil where many plants won’t thrive
- Seepage into your home’s foundation and basement
- Damage to exterior and interior concrete surfaces
Causes for Poor Yard Drainage
Lawn drainage problems are common during spring. Following are some of the causes for poor drainage:
- Wrong slope of the land where water travels to the lowest spot
- Type of soil which may or may not hold or drain water quickly
- Paved areas, driveways, sidewalks or patios which spill water onto your lawn
- Sprinkler systems which may be leaking or running too frequently
- Neighboring yards which may slope onto yours
Solutions for Poor Yard Drainage
The solution to a yard drainage problem depends upon the underlying cause. The most important aspect of any solution for poor lawn drainage is simply finding an alternative place for excess water to go:
- Installing drains in low areas
- Digging trenches to catch standing water
- Installing pipes to route the excess
- Creating a soakaway, an area filled with rocks to absorb excess water
- Repair, seal or level concrete floors and surfaces

With its beautiful Gothic architecture and bell tower, the Memorial Union at the University of Missouri has been slowly deteriorating. This iconic building was built to honor the 117 Mizzou alumni who died in WWI. Due to soil erosion and severe dry conditions, voids and cavities formed beneath the surface. In turn, this caused the concrete slab to become uneven, becoming a significant threat to everything in its path.
A team of engineers, with structural design and environmental engineering experience, inspected the damage. They came to the conclusion that polyurethane foam would be more effective as opposed to using mudjacking. NCFI’s TerraThane Geotech foam system, the best in the spray foam industry, was used to repair the settlement. The area consisted of 1,200 sq. ft under the offices of the buildings and 1,500 lbs of TerraThane was injected into the surface. Unlike mudjacking, 5/8 inch holes were drilled into the surface without creating a mess. The process was quick, easy, effective, and didn’t require the building to be shut down during repairs. All of these factors played a major role in choosing polyurethane foam over traditional methods. Polyurethane fixed all soil issues without creating a burden onto the soil. This makes polyurethane a permanent solution for concrete leveling.
In conclusion, TerraThane costs 60% less than concrete replacement so it was the best choice for concrete leveling. Mark Whitehead, an experienced engineer, commented that “polyurethane played a major role in saving a building so important to the hundreds of thousands of Mizzou alums and future Tigers.”

Most people don’t think their concrete slab can be repaired. And others do not want to make the necessary repairs. In reality, concrete is another maintenance project because it is susceptible to damage, especially when exposed to standing water. Every year, homes and buildings experience concrete slab damage due to heavy rainwater and flooding in the Kansas City area. Such situations can have damaging effects on sidewalks, driveways, patios, walkways, concrete floors, and concrete foundations. The good news, however, is that concrete can be repaired. At Polyjacking.com, we make sound decisions and recommendations to solve your concrete slab problems caused by excess water.
Types of Concrete Slab Problems
Concrete slabs are very porous. This means standing water can easily fill in pores on the surface and eventually break down the concrete. As a result, the concrete may crack, move or even settle.
If you suspect concrete slab damage, inspect the surface and look for the following:
- Concrete cracks – Clay soil expands when wet, and contracts as it dries out. This constant fluctuation, causes voids and holes under the concrete slab. As a result, the concrete surface sinks and forms cracks.
- Uneven concrete or holes in the concrete – Concrete that is exposed to too much water, harsh weather elements, and other issues can cause soil expansion and movement under the surface. This creates uneven concrete, as well as holes in the surface.
Concrete Leveling Services
At Polyjacking.com, we provide repair services for your cracked and uneven concrete by injecting polyurethane beneath the concrete slab. Once injected underneath the slab, it fills in voids and raises slab to its desired level. It also seals cracks and joints underneath the slab, while stabilizing the soil to prevent future settlement.
If you have damaged concrete slabs on your property, contact our concrete repair specialist today. We use the latest concrete repair methods to restore your concrete. For concrete repair services in Kansas City, St. Louis, and the surrounding area, contact us today!
Concrete Slab Problems and Troubleshooting Tips
Concrete slab problems are a common occurrence in basement floors, garage floors, and other concrete surfaces. They go ignored for years until the surface gets worse. Without necessary repairs, cracks may spread and get larger allowing water to seep through the surface. If you know what to look for, most concrete slab problems can be easily identified. Some common slab problems include the following:
- Cause: Plastic shrinkage cracks are very thin cracks that do not affect the condition of the slab. They are usually a cosmetic issue caused by drying and shrinking of the concrete surface. They develop in the first few hours after concrete replacement and before the job is complete. This usually occurs when the concrete is still plastic and shrinks due to rapid moisture loss.
- Solution: There is no easy fix, but plastic shrinkage cracks can be prevented. Make sure the surface does not dry too quickly. Also, use lower water content mixes to prevent too much shrinking.
- Cause: Dusting is chalking at the surface of the concrete slab and can be rubbed off onto your finger. It can be easily damaged by traffic use or with a stiff bristle broom. Dusting can be caused by finishing, floating or troweling of condensation moisture from humid air on cold concrete.
- Solution: Grind or seal the concrete floor surface to remove the top few millimeters of the surface. It will also remove rough spots and any surface indentations from the concrete slab.
- Cause: When looking for scaling, look for loss of mortar. Scaling is caused by deicing salts, freezing and thawing cycles, hard troweling, improper curing or low air content in the concrete mix.
- Solution: It can be prevented by providing a good air void system and making sure salts do not get on the surface until the concrete has dried for at least 30 days. Scaling can also be fixed with concrete grinding. This method removes the top layer of the surface and level uneven concrete.
- Cause: Serious cracking in a concrete slab is an indication of excess water and soil settlement beneath the concrete slab. These cracks are far more serious than surface shrinkage cracks and could lead to the foundation slipping or becoming uneven.
- Solution: These can be fixed temporarily with polyurethane injections directly into the crack. For permanent repair, it is better to inject a polyurethane foam beneath the entire surface to not only fill in cracks but stabilize the soil and fill in voids.
Sinking or Settling
- Cause: By the time your concrete slab has started sinking, settling, or becoming uneven, it is a certain sign that the soil beneath the concrete has settled or developed voids in it.
- Solution: The best long-term solution is polyjacking, which lifts and levels the concrete and has other benefits.
