Void Filling & Soil Stabilization in Denver
Hollow spots and washouts under your slab or foundation? We fill the voids and stabilize the soil with polyurethane before settling gets worse.

Fill voids and stabilize soil under concrete
Before a slab sinks, the soil under it washes out and leaves voids. We inject polyurethane foam to fill those voids and stabilize the soil — supporting slabs, footings and foundations and stopping settlement before it starts.
