Geo Grout


	Manholes Stopping fluid infiltration into a structure or manhole is difficult due to the increase in fluid pressure as the repair process continues. Geo Grout addresses the problem by cutting off the fluid flow from the outside of the structure. Typically the repair process is carried out by advancing a series of injection probes around the structure from the ground surface to the zone in question. The injection process creates a permanent grout plug on the outside of the structure. Since the grout plug is always in compression, an increase in fluid pressure does not affect the repair. Alternatively, the pressure grouting may be carried out through injection probes advanced through the structure walls. These probes are left in place until the grout sets, then removed and the holes repaired. Geo Grout has incorporated site specific grout mixes to stop fluid flows upwards from 45 litres/minute (10 gallons/minute) or more, utilizing these techniques.

	Sewer Lines Fluid intrusion into sewer lines, as in manholes and structures, is addressed by advancing grout injection probes from the ground surface to the source of the leak. The injection process creates a permanent grout plug on the outside of the sewer line. Since the grout plug is always in compression, an increase in fluid pressure does not affect the repair. Geo Grout utilizes video equipment to monitor the pipe enclosure during the repair.

	Dams & Canals In areas where utilities are constructed beneath watercourses, such as dams and canals, the auguring process may disturb the soils around the earth bore. This can create fissure in the soils and eventually lead to piping of the dam or canal water into the earth bore. Geo Grout has pressure grouted the annular space between the earth bore and pipeline utility, filling any available ground fissures in the process. Due to the pressure gradient associated with these structures, a high strength flow-able cementitious grout is used to assure long term durability.
