Have you heard of foam foundation repair? Maybe a contractor or builder mentioned this, and you’re on the search for more information. This article will clarify what exactly “foam foundation repair” is, how it works, and other foundation repair solutions.
What Is Foam Foundation Repair?
Contractors can use structural polyurethane foam (poly) as a standalone service, depending on the problem. For instance, if a water line breaks causing soil erosion, then poly could fill the void and add support to the slab or foundation.
In order for foam to be a viable option, the compressive load (the capacity of a material or structure to withstand loads tending to reduce size), of the home has to handle it. If it can’t, then steel push piers are the better option.
How Does Foam Foundation Repair Work With Helical or Push Piers?
Polyurethane foam is often used in conjunction with helical or push piers. After the foundation is lifted with piers, a void is created under the slab and foundations. Polyurethane foam is injected through the slab to fill the void created to provide additional support and make sure the void is not used as a home for pests.

Compaction or permeation grouting is mainly used for sinkholes and settling foundations.
Compaction grouting is a method where fast-setting polyurethane foam is injected into loose soil. The foam expands, forming balls or columns of dense structural foam. The expansion compacts the surrounding soils and increases the load-bearing capacity.
