Permeation grouting, also known as pressure grouting, fills cracks or voids in rock and pore space in granular soils with a flowable grout thereby forming a cohesive/cemented mass. To achieve the highest quality results, permeation grouting is performed by experienced personnel using safe, controlled, low-pressure injection techniques designed to consolidate pre-determined subsurface zones.
Applications Include:
Strengthen or solidify native geology – granular soil
Water cutoff – reduces the flow of groundwater by creating barriers
Grout prisms for jacking and receiving pits in tunnel
Excavation support – stabilize soils for underground structures
