Can Polyurethane Foam be Used for Structural Foundation Repair?

Yes, polyurethane foam is engineered and rated for load-bearing applications, making it a safe and effective method for structural foundation repair. Often referred to as polyjacking or slabjacking, this technique is used to provide secure support for house foundations and other structural loads.

According to the provided content, using high-density polyurethane foam for foundations offers several advantages:

Lightweight Material: Unlike traditional mudjacking, which uses a heavy slurry, polyurethane foam is lightweight and adds negligible weight to already settling or sensitive soils.
Immediate Support: The foam cures almost instantly into a waterproof, inert state. This provides immediate structural support with no waiting period, whereas other methods may require days to cure.
Durability: The closed-cell structure of the foam resists water intrusion and will not wash out or decompose, helping to prevent the erosion that causes re-settlement.
Non-Invasive: The process requires no heavy excavation and uses very small injection holes (5/8″ to 1″), which minimizes disruption to the property and adjacent structures.

While polyurethane foam is a permanent alternative to underpinning for specific settling issues, it is always recommended to consult a licensed engineer for a definitive diagnosis of your specific site conditions.
