Under‑Slab Void Filling & Stabilization

Voids caused by washouts, plumbing issues, or past movement can undermine your slab. We inject expanding polyurethane to fill voids and re‑support panels, machinery pads, and interior foundations—without tear‑out.

Best for

• Hollow‑sounding slabs and rocking panels

• Voids along dock edges or interior grade beams

• Stabilizing floors prior to coating or equipment anchoring 

How it works

1. Identify voids with sounding and targeted coring if needed.

2. Inject material to fill and densify.

3. Verify support; finish injection ports.

4. Return area to service quickly.
