Soil Compaction and Stabilization with Geopolymers.

When injected into the soil, polyurethane foam expands rapidly, filling voids and forming resin vein structures that promote soil compaction and stabilization.

The pressure generated during the resin expansion — which occurs within approximately 30 to 60 seconds — improves soil density and increases its load-bearing capacity in a precise and controlled manner.

Key advantages of this technology:

▫ Up to 95% curing in approximately 2 minutes

▫ Lower stress on the subsoil (0.14 ton/m³ vs. 1.9 ton/m³ for cement)

▫ Significant reduction in operational interruptions

▫ Greater waterproofing of the treated soil

▫ Improved ground stabilization

▫ Clean process, with no excavation and no environmental impact

▫ Lower overall cost
