Groundwater control for construction

Föredragshållare: Dr Martin Preene, Dewatering Specialist, Preene Groundwater Consulting

Groundwater is a common problem in excavations associated with basements, foundations and tunnels. If not adequately controlled and managed during construction, groundwater can cause a range of geotechnical problems, including running sands, excessive ground loss, base heave and collapse of excavations, resulting in additional costs and time delays. This presentation provides a background to the more commonly used methods of groundwater control and dewatering, and includes a review of the techniques used for groundwater control by pumping (sump pumping, wellpoints, deep wells, ejector wells) and for groundwater control by exclusion (cut-off walls, grouting, artificial ground freezing). Particular applications and challenges of groundwater control are discussed.
