Polyjacking Helps Anadarko Petroleum
Anadarko 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.

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.

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 foundations, including:
- Mud in your lawn where children and pets cannot play
- Potential lawn problems due to insects and fungi
- Poor soil where many plants won’t thrive
- Seepage into your home’s foundation and basement
- Damage to the exterior and interior concrete surfaces
Causes for Poor Yard Drainage
Lawn drainage problems are common during spring. Following are some of the causes of poor drainage:
- The 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
When to Call an Expert
Whatever your drainage problems, it is often useful to call in an expert to diagnose and solve your water issues. If you have poor drainage from concrete surfaces or other issues with your concrete patio, driveway, sidewalks, or foundations, Polyjacking.com is the Kansas and Missouri expert at concrete leveling and repair.

With its beautiful Gothic architecture and bell tower, the Memorial Union at the University of Missouri has unfortunately 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.
Determining a Solution for Memorial Union
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, which uses holes around 2-3″ in diameter, 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 foam fixed all soil issues without creating a burden on the soil. This makes polyurethane foam 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.

Polyjacking vs. Traditional Mudjacking
When compared with traditional mudjacking, polyjacking is the new kid on the block. It is quickly making a name for itself, though. Mudjacking costs less but is looked at as more of a temporary fix, whereas polyjacking is considered a permanent repair.
The method of traditional mudjacking involves drilling holes in your driveway or other surface and pumping a slurry mix underneath. The slurry is commonly made up of cement, mud, sand, and crushed limestone, which is mixed with water. The slurry flows under the concrete and the slab is raised until it is once again even with the rest of the driveway or patio. Once pumping is done, the holes are patched over.
Polyjacking is similar to the mudjacking application: holes are drilled into the slab that needs to be repaired but instead of a slurry mix, polyurethane foam is injected. The foam expands, filling the voids and raising the concrete to its required height. The holes that were drilled are patched over and you’re good to go in a fairly short amount of time.
Now you may be thinking to yourself that mudjacking is the least expensive option so that is probably the best way to go. However, there are a few more points you may want to consider before you make your decision.
Benefits of Polyjacking
As we learned above, both methods involve drilling insertion holes into your concrete. Polyjacking uses holes that are around 5/8″, or the size of a penny, whereas mudjacking holes can range from one to two inches, a sizeable difference. The foam expands between four to fifteen feet from the injection point. Due to the thickness necessary in the mudjacking slurry, it can only spread about a foot or two. So, not only are the polyjacking holes smaller, less of them are needed for the same coverage, fifty to seventy-five percent less, in fact!
We mentioned that mudjacking slurry is thicker than foam and it is also considerably heavier. A cubic foot of slurry weighs a hundred to a hundred and fifty pounds, which is a considerable amount since the same volume of polyjacking foam weighs around three to four pounds. If the underlying soil is already unstable, the weight from the slurry can cause more problems than it solves, as heavier mud can worsen existing problems.
Polyjacking foam expands under the concrete, filling any voids and stabilizing the soil underneath the slab. Due to the thickness of the slurry, it cannot accomplish the same thing. Although numerous holes are drilled to try and get a good spread of mud, completely filled voids are rarely achieved. Additionally, water can wash out the mudjacking slurry, leaving you with the same problem, or possibly a worse repair in the future. Polyjacking foam won’t wash out and is considered a permanent repair, not a temporary fix.

Uneven Concrete and Tripping Hazards
Do you have an uneven concrete sidewalk or walkway on your property? It’s probably a good idea to get it fixed. After all, it will only get worse over time, creating a trip hazard and a serious liability lawsuit. In fact, more cities are mandating leveled sidewalks and requiring homeowners to pay for them.
So what causes uneven concrete? Due to maturing tree roots and weak soils, the majority of concrete slabs will encounter settlement. In many cases, water is the culprit of expansive soil problems. It weakens the soils, causing cracks and settlement underneath the slab. Polyjacking keeps water away from the slab and prevents future settlement.
The professionals at Polyjacking.com can lift and level sunken concrete for the following applications:
- Garage floors
- Pool decks
The concrete raising process involves drilling small 5/8 inch holes in the affected area of the concrete. Polyurethane is pumped into the drill holes. The polyfoam expands and fills in voids under the slab. Finally, the slab is raised back to its original position and the holes are patched. Since polyurethane cures within 15 minutes, the area is ready for traffic the same day and your liability is gone.
Concrete Leveling Prevents Trip Hazards
Tripping hazards can occur on any uneven concrete surface at universities, schools, hospitals, businesses, and just about any other property. With polyjacking, injuries can be prevented to reduce liability. Contact Polyjacking.com for effective concrete leveling in the Kansas City and St. Louis area.
What 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
So 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.
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.
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.
