PolyLevel is a polyurethane foam that is injected into the slab. This is done by drilling tiny holes and injecting the foam underneath and into the voids.
This walkway is a dangerous tripping hazard. If someone were to walk over this, they could injure themselves.
Once our crew is done injecting the polyurethane foam, the walkway will be brought to a level position. Now, the walkway is safe to walk on!
