What Is PolyRenewal™?: Our Polyurethane Foam Concrete Leveling Method
Uneven, settled, and cracked concrete slabs are a trip hazard and compromise your home’s foundation. Addressing this problem now prevents expensive repair bills in the future.
Unfortunately, traditional repair methods like mudjacking don’t last, while concrete replacement is invasive and expensive. You need a product that addresses the root cause of damaged concrete—the soil under your slabs.
Matvey Foundation Repair has a solution. Our PolyRenewal™ polyurethane foam can safely lift and level concrete, resulting in safer and more even surfaces. Learn the benefits of this custom-engineered product and how it works.
What’s the Problem with Sinking, Cracking Concrete?
Concrete is one of the strongest materials around, but it isn’t immune to damage. When the soil under your property compresses, it can cause concrete structures like sidewalks, driveways, and porches to crack and settle.
Uneven, cracked concrete is not just a tripping risk. It can also harm your home’s foundation, which might cost tens of thousands of dollars to repair.
Old Concrete Lifting Methods
In the past, contractors lifted concrete with mudjacking—also known as slabjacking. This outdated method involves drilling holes into damaged concrete and pumping water, soil, sand, and cement under slabs to restore them to their previous level.
Most contractors now agree that mudjacking isn’t the best solution for repairing concrete for these reasons:
- It doesn’t last very long
- It doesn’t always lift concrete evenly
- It’s messy
- It can harm underground utilities
- It often comes with poor warranties
- It’s not environmentally friendly
What Is PolyRenewal™?
Matvey Foundation Repair’s PolyRenewal™ is an alternative to mudjacking. We can inject this polyurethane foam under your concrete slabs to lift them to their correct position. Once injected, the foam expands to around 15 times its original volume, which makes it easy to fill voids and raise settled concrete.
PolyRenewal™ cures quickly and reaches its full strength in just 15 minutes. We can also apply it before concrete construction to improve soil strength and stability.

How Does PolyRenewal™ Work?
Our process for injecting PolyRenewal™ is as follows:
- Drilling penny-sized holes in your concrete
- Inserting injection ports into these holes
- Injecting PolyRenewal™ under concrete slabs
- Sealing and smoothing over the injection ports
PolyRenewal™ might even safeguard your concrete slabs from slippage and fill cracks in your foundation.
Benefits of PolyRenewal™
The advantages of using our polyurethane foam include:
- PolyRenewal™ weighs just 4 lbs per cubic ft, making it much lighter than standard fill materials. However, it can still support heavy loads and is ideal when denser fill material forces excessive load on weak soils.
- Once it cures, PolyRenewal™ becomes impervious to water, meaning it won’t wash away—unlike mudjacking.
- PolyRenewal™ is environmentally friendly and won’t harm your soil or the surrounding ecosystem.
- This product cures in just 15 minutes, so you can use your concrete structures again shortly after application.
- We can adjust PolyRenewal™ for different applications, soil conditions, and types of weather.
- PolyRenewal™ injection equipment is compact, allowing us to access confined areas. Plus, the injection process is less invasive than other slab and foundation lifting methods.
