Construction dewatering, the temporary lowering of the groundwater, has been practiced by Moretrench for more than 90 years and the company is recognized as an industry leader and an innovator in the field. Methods include deep wells, wellpoints, and ejectors. Under some circumstances, artificial recharge can be used to minimize the potential side effects of excessive groundwater lowering during construction.
Groundwater control can also be provided by the installation of subsurface barrier walls or by ground modification methods. In addition to construction applications, groundwater control methods can be used for environmental containment and structural seepage control or for stabilization of waste products such as coal combustion residuals.
