How PolyLevel® Works

As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, concrete will sink, creating an uneven surface.

PolyLevel uses a high-density polyurethane foam to stabilize and lift sinking concrete slabs. BQ Basement Systems creates a waterproof concrete repair that's much more permanent than mudjacking and other common concrete repair methods.

PolyLevel step 1: drilling injection holes


Small 5/8” holes are strategically drilled in the slab.

PolyLevel step 2: installing injection ports


Injection ports are installed.

PolyLevel step 3: injecting polyurethane foam


Polyurethane foam is injected beneath the concrete to fill voids and raise the slab.

PolyLevel step 4: sealing holes and control joints


Holes and control joints are sealed.

PolyLevel® Applications

BQ Basement Systems has the expertise and equipment to quickly raise and level many types of slab-on-grade concrete, so you can use those areas around your home without worry.

Traditional Concrete Lifting vs PolyLevel®

Before PolyLevel, there were two basic options for lifting and leveling concrete: mudjacking and slab replacement. Both approaches have limitations and disadvantages. PolyLevel offers many advantages over traditional concrete leveling methods:


Foam Injection
Mudjacking or Slabjacking
Cure Time 15 minutes 24 hours or more
Material Weight 2 lbs per cubic foot 100 lbs per cubic foot
Hole Size 5/8" (size of a penny) 1" (size of a quarter)
Waterproof Yes No

If your concrete is structurally-sound, why replace it? Replacing the concrete won't fix the soil problem that's causing the settlement. Concrete leveling is the answer.
