Chemical grouting has been successfully used for over 40 years to control the movement of groundwater in a wide variety of applications including tunnels, subway systems, sanitary sewers, mines and construction projects.
Groundwater infiltration can be due to either primary or secondary permeability. When both types of permeability are present, mitigation requires versatility and cooperation between multiple project participants.
Standard Cementitious Grouts have two main limitations: One, the inability to effectively penetrate rock microfractures or dense, silty soils, and two, poor performance due to deleterious curing problems inherent in standard concrete.
Many U.S. municipalities and utility districts face federal Environmental Protection Agency (EPA) mandates to correct water quality problems caused by discharges from combined sanitary and storm sewer systems
The WIPP in New Mexico was created as an R&D facility to demonstrate safe, long-term disposal of radioactive wastes. However, before waste could be shipped to the plant, fissures in the underground salt cavern had to be sealed.
