Soil Stabilization Grouting
The injection of a multi-component chemical grout or an expansive hydrophobic foam grout into various rock strata, soil and voids, creating a grout curtain or grout bulbs which stabilizes the soil, and provide structure support.
The chemical grout is pumped under pressure from a delivery system that is either above ground or located near the grouting area. This liquid mixture is pressurized through the rock, or soil, or structure wall filling voids and creating a watertight grout/soil matrix preventing groundwater infiltration/exfiltration and potential soil erosion. The chemicals predictably react within 30- 60 seconds to seal off infiltration and are controllable from the delivery system. Grouting pressures measured at the injection point are monitored to insure that the materials are pumped at higher pressures than the groundwater pressures.
