APD Repairs Sinking Concrete

Sinking Concrete?​ Don’t Replace! Repair!​


How Does Poly Work?

Poly is a two-part hydrophobic chemical injected into the sub-soils through dime-sized holes. It then expands into foam, displacing water to fill voids under homes, and re-level pool decks, driveways and other concrete slabs. It hardens like concrete. Poly Foam compacts the loose soils to increase the load-bearing capacity of the area. It will seal or raise concrete and stabilize it. Ready to walk or drive on Immediately!​​​​​​​

100% Hydro-Insensitive

What do we mean by ​​Hydro-Insensitive?

The foam APD uses is Hydro-insensitive because it forms high quality foam even in the presence of water.​​​​​​​​​​​​​
This includes during the injection, reaction, and curing phases. Foam that fails during the injection phase will leave the surrounding water cloudy, signifying that the raw chemicals have dissolved into the water.​

100% Eco-Friendly

The Foam we use is made in the USA!​

Our foams are environmentally friendly, consisting of 39-49% renewable and recycled materials. Designed specifically for different applications, APD only uses top-of-the-line material made 100% in the USA.

Before and After Pictures

Three Step Poly Injection Process to Level Concrete

Our polyurethane foam method uses the concrete slab itself as a means of delivering poly foams that raise concrete, fill voids, and stabilize soils. A ⅝” hole is drilled through the slab into the subgrade. A tapered delivery port is installed into the ⅝” hole. The injection gun is connected to the port. The injection gun delivers the polyurethane material through the port and slab. Expansion of the material occurs within seconds, compressing loose soils and raising concrete​.


First we drill a 5/8 inch hole (dime size) in the concrete.


Second we pump the two part chemical to lift and stabilize the concrete.


Third step, we patch the hole.

Why Polyurethane concrete is important

Polyurethane concrete systems provide for a completely seamless system that is resistant to attack from lactic acid, oleic acid and bacteria. It is also resistant to other caustic chemical chemicals common to food & beverage settings.

Pool Decks

Uneven pool deck? Reduce trip hazards. APD Advanced Stabilization specializes in poly deep foam injections. We stabilize and raise the concrete around your pool, making your pool area safe and attractive again.

Concrete Slabs

A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving

Concrete driveways requires virtually low to no maintenance, which saves both time and money in the long run. It can last over 20 years and weeds will not grow on the paved area. Considered one of the strongest material for landscaping, it can withstand more wear and tear then other choices.


A concrete walkway can be any type of path made of concrete. Concrete paths can be created by using poured concrete, concrete paving stones, or concrete blocks. Concrete is a popular choice for creating pathways because it is usually simple and inexpensive to install.

Void Fills

This innovative method of foundation void filling uses polyurethane foam to achieve slab stability. This high-density foam is injected into small holes drilled into your concrete slab. Upon injection, the polyurethane foam chemical reacts causing an expansion to fill and seal void defects.

Trip Hazards

Repair your sidewalks with poly foam injections

Trip hazards are a safety problem whether at home in the neighborhood, or in a commercial setting.

Uneven concrete isn’t just a small pain. It can actually cost you your homeowners insurance. Any lift over 1/4″ is considered a trip hazard. If someone trips over a trip hazard on your property you could be liable!

Poly foam injections will raise and level your current walkway back to even.

I called a lot of companies to take a look at my water issues in my basement. APD was the only one who provided a solution that sounds like it was going to fix the problem, not just selling on something. Danny was great in walking me through the entire process, and providing a quick quote. When the crew arrived, they were professional and very friendly. They walked us through the process at each step so we knew exactly when they were coming and going as well as what they were working on that day. Once complete, they even took the time to re-compact the soil (multiple times) so it looked nice and was sloped correctly from the house. During the work they had to remove a part of the fence. During the removal the fence was damaged slightly. Rather than trying to fix it and not tell me. They went out and got a new post and replaced it the correct way, keeping us informed of the entire process.I will have to wait till next hurricane season to see if the work done will seal the basement from water but from what I experienced, I have no doubt that I chose the correct company to fix my issue. I would highly recommend APD for any foundation repair and waterproofing.

We were very happy with APD, from the estimate right through completion of the work. Leanne did a great job communicating with us through the whole process and even did a follow up call a week after the project was complete. The guys did an awesome job and really took their time to do a great clean up after they were done. We highly recommend APD!
