PolyLevel Foam Lifts and Levels Concrete

Monday, October 26th, 2020 by Alexis Wolfe

How Does Concrete Become Uneven?:

Concrete is frequently installed overtop of loose soil during a home's construction. Over time this concrete can be moved as the soil settles, shrinks, or washes away. This results in the uneven, sinking, or tilting concrete surfaces that PolyLevel is used to raise. 

What is PolyLevel?: 

PolyLevel is a high-strength polyurethane foam used to raise and level concrete slabs and fixtures. It is simultaneously light-weight, environmentally friendly, and capable of lifting and supporting heavy loads. 

How PolyLevel is Installed: 

PolyLevel is injected beneath concrete fixtures through a series of strategically-drilled pea-sized holes. This foam fills the gap between the concrete fixture and the compromised soil. As it dries, PolyLevel expands, pushing slabs and concrete fixtures upward. These pea-sized holes are then patched and become nearly invisible. Once it cures, PolyLevel will provide permanent support between the concrete slab and the ground. 

Products Used in Conjunction with PolyLevel: 


NexusPro Joint Sealant seals cracks and joints in concrete slabs to keep out water that can soften and wash away the soil underneath.  


SealantPro dramatically extends concrete's lifespan by defending it from damage caused by water absorption and chemicals, which can result in pitting, flaking, and staining. 

The Advantages of PolyLevel: 

Traditional methods of concrete repair (like concrete replacement and mudjacking) are known for creating unattractive aftereffects. Mudjacking especially is also known for washing out and drying out, providing only a temporary solution. 

PolyLevel on the other hand provides a permanent, less invasive solution to uneven concrete that will not wash out, dry out, or create an ugly patchwork effect on your fixtures. It dries within 15 minutes, and its clean installation system minimizes disruption to slabs and property.
