Inquip Associates

Inquip Associates, Inc. (Inquip) is a specialty geotechnical contractor founded in 1977. Inquip traces its roots to the beginning of slurry trench technology in 1950 on the Terminal Island Project, in California, for the Los Angeles Port Authority. This was the world's first industrial application of the bentonite slurry trenching method of excavation. The company's capabilities include underground seepage barriers; cast-in-place and precast slurry walls for support of excavations; deep soil mixing; leachate collection systems; liners; pressure and jet grouting; and reactive barriers. Inquip uses the slurry trench method of excavation for a wide range of construction, including soil-bentonite cutoff walls; cast-in-place concrete slurry walls; and biopolymer drainage and recharge trenches.
