Poly Foam Injection

Trusted Foundation Repair from Residential to Heavy Commercial

Straight Line Construction has successfully performed polyurethane foam injection on hundreds of projects throughout Colorado, New Mexico, Arizona, and Wyoming.

What is poly foam injection? 

Poly foam injection is similar to mud jacking in that holes are drilled in the existing concrete and a stabilizing material is pumped to fill voids and re-level the concrete. Instead of a cement slurry, polyurethane foam injection relies on a stable, durable, light weight foam that expands as it is injected to lift and re-level the concrete. 

How is poly foam injection done?

Poly foam injection is performed by drilling small diameter holes through the existing concrete. The expanding polyurethane foam is then injected. The foam expands as it is placed and fills voids and raises the existing concrete in a controlled manner.

Similar to mud jacking, polyurethane foam injection can be used to re-level concrete slabs and flatwork that have settled. Settlement of these features can cause improper surface drainage that may result in runoff water being directed towards structures which can adversely affect building foundations and their performance. Uneven or out of level concrete slabs and flatwork can also cause significant safety and trip hazards. 

Polyurethane foam injection is a relatively non-disruptive technique that can be used to re-level existing concrete slabs and flatwork to re-establish positive surface drainage away from structures and improve safety associated with tripping hazards. Polyurethane foam injection requires very little equipment and disturbance of the existing concrete and surrounding areas is minimal. 

In what applications can this technique be used?

Polyurethane foam injection can be utilized in a variety of applications including:

  • Raising existing concrete slabs and flatwork to re-establish positive drainage away from structures

  • Re-level existing flatwork such as sidewalks and patios to reduce hazards associated with tripping

What advantages does poly foam injection offer?

Some of the advantages of polyurethane foam injection include:

  • No drill spoils are created

  • Quick installation

  • Damage to existing concrete is minimal

  • Can be performed in most weather conditions

  • Impacts on existing landscaping and surrounding areas are minimal

  • The polyurethane foam is a very lightweight material which reduces risk of the added material causing additional settlement of existing concrete flatwork.
