  • Predrainage Dewatering

    Predrainage, the lowering of the groundwater table below the proposed construction subgrade, is often a requirement to allow deep excavation or soft ground tunneling operations to be accomplished in the dry. The primary tools of predrainage are deep wells, wellpoint systems, and/or ejector systems. The selection of the optimum system is site ...

  • Membrane Interface Hydraulic Profiling (MiHPT) Solutions

    Rapid screening tools reduce investigation time and save money by quickly identifying areas of the site for further investigation with more costly definitive technologies. The MiHPT allows for rapid reconnaissance of sites to zero in on source areas and plume cores while identifying both transport zones and contaminant mass storage zones.

  • Barrier Techniques

    Impermeable subsurface barriers contain or inhibit the flow of groundwater. They may be installed down gradient of a known contaminant source, such as a landfill, to prevent the migration of contaminated water off site, or up gradient of a contaminated zone to prevent the flow of clean groundwater down gradient. Geotechnical methods used by ...
