Soil Stabilisation / Permeation grouting / retention of soils / chemical consolidation
A method for changing the structure of the ground by filling migratory voids and by doing so, increase the density of the ground, increase the bearing capacity and reduce the Coefficient of Permeability. Permeation grouting involves injecting a low-viscosity grout into the spaces between soil particles, improving the ground without significantly disturbing its structure. It can be used to increase soil strength and reduce groundwater flow, depending on the ground conditions and grout selected. The uses of chemical consolidation are numerous and based on the changing in nature of the sands and gravels by sticking all the particles together to form a near homogeneous impervious mass. Chemical consolidation uses are underpinning, water cut off and consolidation/stabilisation to stop a "running condition," the retention of soils providing a vertical face.
Uses are as varied as the voids to be filled.
