Repairing Rocking Slabs

Written by Colt Hullander | Apr 19, 2022 2:00:00 PM

Loose, unstable slabs with voids underneath are often referred to as "rocking" slabs due to their movement when forklifts cross over them. Rocking slabs are a common problem in many warehouses. Left un-repaired, they can cause damage to equipment and injury to workers. Eventually, rocking slabs will require replacement if they are not repaired properly.

Rocking Slabs Can Cause:

  • Slab Deterioration Over Time
  • Floor Destabilization
  • Damage to Material Handling Equipment & Loads
  • Trip Hazards & Litigation Risk

How to Repair Rocking Slabs:

  1. Inject high-strength, high-density polyurethane foam underneath the slab for lasting support.
  2. The polyurethane expands to fill any voids underneath and cures to support 14,000 lbs/square foot.
  3. Easily clear excess foam from the surface of the slab.
  4. Repaired slabs are traffic ready in just 15 minutes!
