INQUIP Associates, Inc., a speciality geotechnical contractor, traces its roots back to the beginning of the slurry trench technology in 1950 on the Terminal Island Project. This was the first trench ever excavated under bentonite slurry for an industrial application. The company was founded in 1977 to continue and further develop the activity of the groundwater control division of Industrial Engineering and Equipment Corporation, founded by Mr. Charles H. Toll, one of the pioneers in the development of the slurry trench method. Mr. Toll was instrumental in the promotion and construction of economical underground seepage barriers, including the Terminal Island Project.

INQUIP's main activity from its creation to the early eighties was related to the installation of soil-bentonite cutoff barriers and liners. In order to utilize the wide experience of its management team and to be able to satisfy more efficiently the needs of its clients, INQUIP expanded its product line to other geotechnical techniques. This carefully controlled growth process is expected to continue in the future. Many of the speciality techniques offered by INQUIP have applications for the control and mitigation of pollution associated with landfills and waste management facilities.

INQUIP offers capabilities for the installation of:

All types of underground seepage barriers
Cast-in-place or precast slurry walls for support of excavations
Deep soil mixing
Leachate collection systems
Liners
Pressure and jet grouting

INQUIP has experience with federal and state regulations governing health and safety for remediation work on the hazardous and toxic sites.

INQUIP's major goal is to provide excellent service to its clients and to maintain a high level of quality construction. Only qualified, technically capable field managers oversee site construction. The company management strongly believes that close understanding and cooperation with the owner and the engineer are essential in resolving technical difficulties and achieving high performance. Inquip looks forward to working closely with its clients for the successful completion of their projects.
