For decades, Avanti's grouts have been used in geotechnical applications to stabilize soil before, during and after construction phases. Below are three excellent examples:


Perhaps the largest injection grouting project in North America, the City of Dearborn, Michigan was mandated by EPA to build a series of underground storage tanks. Because of nearby rivers and the depth of the tanks, permeability of the site had to be reduced by creating an impermeable grout curtain to a depth of 200 feet. Controlling groundwater before construction was vital. The product that yielded results which were 10x better than the engineer’s minimum requirement was Avanti’s AV-100 Chemical Grout.


During construction of a tunnel 100 feet below a major metropolitan area, a tunnel boring machine (TBM) went off course due to the shift in substrate from clay to sand. Rather than dig a new shaft to retrieve the TBM, project engineers were successful at stabilizing the sandy soils ahead of the boring operation using Avanti's injection grout. The stabilization saved the contractor several weeks and almost a million dollars in additional expenses.


Avanti’s injection grouts stop groundwater migration and improve mining operations in potash, diamond, salt, limestone, coal, gold and copper mines. By permeating the various geologic strata, the grout creates a mechanical lock throughout the network of super-fine cracks. Capable of withstanding significant head pressures, our injection grouts permanently control infiltration after construction in mines and underground structures.
