Get a faster, affordable alternative for concrete slab repair and foam foundation repair with PolyLevel.
As patios, walkways, driveways, and concrete steps sink, they can crack and create uneven surfaces. Sinking concrete is unsightly, and it can create a tripping hazard. Traditionally, this problem was repaired by a process called mudjacking, or slab jacking. Mudjacking: a repair technique for lifting concrete slabs that have settled over time with a mortar-based mix called slurry. AquaGuard Foundation Solutions offers a faster, more effective, and less invasive approach to concrete leveling with the PolyLevel® foam foundation repair system.
PolyLevel® Foam Foundation Repair System
The PolyLevel® foam foundation repair system involves injecting a structural-grade, expanding, two-part polymer foam under the concrete for a durable, long-lasting solution. The polymers come out at very high pressure in liquid form, filling any gaps or voids underneath the concrete and then engaging with itself and expanding within approximately seven seconds. The difference with PolyLevel is that the foam is flexible during installation and thus can fold back over itself for a gentle, accurate lift. PolyLevel is completely inert and waterproof, so there’s no chance it will wash out over time, and it weighs an astonishing 4 lbs per cubic foot, so it doesn’t add discernible weight to the underlying soil below.
PolyLevel® vs. Mudjacking?
PolyLevel and mudjacking virtually serve the same purpose: to raise concrete. When foundations begin to sink, it’s usually because there are voids that exist underneath the concrete slab. It’s nearly impossible to restore the foundation to its original level of elevation without raising the concrete and filling those voids underneath the structure. While PolyLevel and mudjacking are similar in function, there are some differences between the two you should take into account before choosing one over the other.
- Mudjacking is fairly inexpensive and is a procedure that most contractors are familiar with.
- The injection slurry is made up of natural materials with little to no negative environmental impact.
- The texture of the slurry is too rough to completely fill the voids, which increases the likelihood of your foundation sinking in the future.
- Mudjacking is a short-term fix and will have to be repeated every few years or less.
- The injected materials weigh 30 times more than polyurethane and can cause a new round of sinking beneath the concrete slab.
- The slurry materials are prone to washing out if exposed to common causes of foundation damage (poor drainage, underground water pipe leaks, heavy rainfall, etc.).
- The injection is a long-lasting procedure.
- Light in weight, which will not cause additional foundation sinking and will flow easily during the injection process.
- Dense enough to completely fill the voids below sinking foundation.
- The soil mixes well with the polyurethane injection and gets stronger over time.
- Much smaller injection hole that will make the end results more attractive.
- Fewer contractors have access to this procedure.
- Equipment and materials are more expensive than mudjacking and often not available to smaller contractors.

While most concrete contractors don’t offer polyurethane injection as one of their repair options, we are very familiar with this state-of-the-art technology. AquaGuard Foundation Solutions provides PolyLevel® foam foundation repair and concrete repair services in Alpharetta, Lawrenceville, Sandy Springs, Norcross, Stone Mountain, Gainesville, Roswell, Athens, and other local areas.
PolyLevel® concrete repair offers important ADVANTAGES:
Strong but light.
PolyLevel® weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyLevel® ’s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than another form of concrete repair, mudjacking.
Once cured, PolyLevel® will not wash away. PolyLevel® ’s waterproofing properties can be beneficial in certain applications. Learn more by contacting AquaGuard Foundation Solutions!
Stable and inert.
PolyLevel® does not react with soil or moisture; it will not leach harmful chemicals into the soil. This makes it an eco-friendly form of concrete repair.
AquaGuard Foundation Solutions can help minimize downtime with PolyLevel® concrete repair. Full loading of the foundation, roadway or other structural elements can usually happen about 15 minutes after the material is injected.
Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. An experienced applicator from AquaGuard Foundation Solutions can factor not only the weight of the structural element but also soil characteristics and temperature and weather conditions. Special formulations of PolyLevel® are possible for applications where water must be displaced.
PolyLevel® injection equipment isn’t bulky, enabling applicators to access confined areas for concrete repair. When properly injected, PolyLevel® is not as messy or disruptive as other slab and foundation-lifting techniques.
Polymer injection with PolyLevel® solves soil settlement and stabilization problems
In the past, contractors often raised settled concrete by pumping a liquid mortar beneath the settled section (called mudjacking). But this pumping process is hard to control, and the added mass of the mortar puts even more weight on the soil. PolyLevel foam is a more effective concrete repair alternative.
Fortunately, foundation and concrete repair specialists now have a new technique that’s more effective at raising settled concrete. Polymer injection with PolyLevel® harnesses the expansive force of a structural grade geopolymer to provide fast concrete leveling, fill voids in soil and strengthen soil that has poor load-bearing qualities.
The PolyLevel polymer consists of two separate liquids that are combined right at the injection nozzle to trigger a chemical reaction that turns the blended ingredients into expanding, high-density foam. The foam flows into voids and between loose soil particles, expanding to about 15 times its initial volume. This expansive action effectively lifts settled concrete. An experienced PolyLevel technician, like those at AquaGuard Foundation Solutions, can control the application to create just the right amount of raising pressure.
The polymer begins to harden quickly after doing its raising work. Within just 30 minutes, it reaches 90% of its final strength, enabling damaged concrete roads and slabs to be put back into service right away. The speed of PolyLevel polymer injection repair is another huge advantage over mortar pumping.
In addition to lifting and realigning settled and/or shifted concrete, polymer injection can be done prior to construction to improve soil stability and strength. PolyLevel injections as deep as 20ft.-30ft. are possible.
