What is URETEK Deep Injection® (UDI)?

Structural Repair projects involving loose soil can be disruptive and expensive. At URETEK, We know they don’t have to be.

We pioneered the quick, convenient, reliable alternative: URETEK Deep Injection® (UDI).

What is URETEK Deep Injection® (UDI)?

URETEK Deep Injection® involves the injection of a geotechnical grade polyurethane into base and subgrade soils to increase the load-bearing capacity on sunken concrete slabs. This is achieved by injecting the polyurethane through small, dime-sized holes drilled directly through the pavement structure to depths determined by site-specific analysis. Our URETEK 486 Star® material flows easily into voids and weak zones within the soil mass below. Through a controlled chemical reaction, the expanding polyurethane compacts surrounding soils and applies controlled pressure on targeted areas of the affected pavement above. If needed, a multi-injection design plan is utilized to return the concrete to its original grade in a slow and controlled manner. The composite material quickly cures into a strong, dimensionally stable, and water-resistant geo-material, providing years of reliable service.
