We Fill Voids

The Prolift Process


When concrete settles, it can cause serious damage to the structures they support. In most cases, concrete settlement can be traced to the dehydration and shrinking of the soil under the concrete, water erosion, poorly compacted subgrade and the washout of soil.


In each situation, a void is created under the concrete slab by the shifting of the soil or by a reduction of soil volume. The concrete may not be sufficiently strong enough to hold the load, causing the stressed concrete slab to crack, break, and eventually settle to fill the void.


The Prolift Process

1. First, a series of 5/8" holes are drilled in an off-set pattern.


2. A two-part resin-based specialized poly-urethane foam is injected into each drilled hole leaving time for the foam to expand, making sure to fill all voids until the concrete is then lifted back to original height. 


3. Once the concrete is preserved, existing voids are perfectly filled and the concrete panel is completely supported and undersealed. The solid, dense polyurethane foam material is unaffected by water eliminating future water issues after work is performed and is complete concrete may be used immediately. The holes are then filled with high-density cement grout and finished to match the existing concrete.


Common Causes of Voids

  • Dehydrated Soil Beneath A Slab

  • Poorly Compacted subgrade

  • Soil Washout — Plumbing Leaks

  • Water erosion (drains, sub pumps, etc)

  • Animals and pests

Prolift Advantages

  • Very low viscosity.

  • Water impermeable polyurethane foam

  • Cures as fast as 15 seconds.

  • Small 5/8' holes, versus traditional 2 and 1/2" mud jacking holes

  • Light weight foam, over most other materials that are heavy and water based and can shrink over time.

  • Poly-urethane foam is strong, supporting over 50,000 pounds per square foot

  • Much more cost effective than a complete concrete replacement

  • Poly-urethane cures quickly, allowing you to walk on the surface within seconds

  • Unlike other products, poly-urethane will not break down over time

  • Most void fills take up to an hour with PROLIFT
