In Salt Lake City, Utah, a historic brick structure built in 1893 showed signs of foundation settlement. The building's sandstone foundation presented a challenge. Traditional stabilization methods like installing helical piers could potentially cause further damage. Rhino Foundation Systems proposed a solution using polyurethane foam to stabilize the foundation. This case study examines how this approach addressed the building's foundation problems.

Powerful Polymers

The technicians selected AP Lift 430 polyurethane foam for the project. This foam was chosen for its ideal soil stabilization and structural support properties. The plan involved injecting the foam beneath the footings to provide a stable support platform. This method would achieve the desired stabilization without requiring extensive excavation.

Painless Procedures

The project began with a detailed site assessment to understand the extent of the settlement and soil conditions. Following this, the team designed a plan to install 63 deep foam injections under the foundation, ensuring comprehensive coverage and stabilization. Specialized equipment was then used to perform these deep injections, with the foam strategically placed to improve the soil and stabilize the foundation.

Rapid Results

The project delivered several key benefits. Deep foam injections improved the soil and provided a strong platform for the foundation, ensuring effective stabilization. The non-invasive process precluded the need for extensive excavation, preserving the structure and minimizing disruption. Notably, the project was completed in just two days, significantly reducing downtime and disturbance to the area. Finally, the polyurethane foam injections offered a cost-effective solution compared to traditional stabilization methods, making it an economically viable option for similar foundation challenges.
