Sinking Sidewalk Leveled in Saint Louis, MO

A sidewalk in Saint Louis, MO, was unleveled and needed to be repaired before potential tripping hazards emerged. This needed to be addressed, so the homeowner decided to give Woods a call. To solve this issue, PolyLevel™ was used. This system works by drilling pea-sized holes into the concrete and injecting a polyurethane foam underneath. The foam then expands, lifting the concrete slabs up to level them out. Next, NexusPro™ was used to fill in the gaps in between the concrete slabs. With these systems in place, the homeowner can rest easy knowing their concrete is in great shape!

Cracked and Uneven Driveway Repaired in Saint Louis, MO

A driveway was sinking in Saint Louis, MO, causing it to crack and become uneven. To solve this issue, the PolyLevel System was first installed. This will stabilize, lift, and level the concrete slabs with high-strength polyurethane foam. Pea-sized holes were drilled into the concrete and the foam was injected to fill the void underneath. This installation technique allows the foam to expand as it cures, precisely lifting the slab back up. Additionally, NexusPro Joint Sealant was installed. This will seal the joints and cracks in the concrete. It will provide long-lasting flexibility and stand up to harsh weather conditions.
