Dewatering and Groundwater Control
Pre-drainage dewatering to lower the groundwater level below proposed subgrade is a critical first stage of many construction projects where excavation at depth is required. Deep wells, wellpoints and ejectors are the primary tools of pre-drainage. Groundwater control by cut-off or containment can be achieved by both physical and geotechnical methods. Moretrench’s range of dewatering and groundwater control methods allows selection of the optimal approach as a function of the subsurface conditions and project requirements.
