For decades, Avanti grout has been used in geotechnical applications to stabilize soil before, during and after construction phases. Below are 3 excellent examples:
Perhaps the largest chemical 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 200ft. Controlling groundwater before construction was vital and the product that yielded results which were 10x better than the engineer’s minimum requirement was Avanti’s AV-100.
During construction of a tunnel 100 feet below a major metropolitan area, the Tunnel Boring Machines went off course due to the shift in clay and sand substrate. Rather than dig a new shaft to retrieve the TBM, project engineers were successful at stabilizing the sandy soils ahead of the boring operation with Avanti Grout. The stabilization saved the contractor several weeks and almost one million dollars in additional expenses.
Avanti’s chemical 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, Avanti Grouts permanently control infiltration after construction in mines and underground structures.
