How prolonged rain can affect your building

Water leaking into the basement after heavy rain is a common occurrence. Water always finds a way, so basement waterproofing and adequate drainage are especially needed in cases where groundwater is likely to build up in the soil and cause a rise in the water table closer to the surface.

Underground car parks, basements, lift pits and even buildings that are cut into a hillside (making them partially subterranean) are often subject to increased hydrostatic pressure during a heavy or prolonged rainstorm. The hydrostatic pressure from the rising water table and the lateral pressure from saturated soil are pushing the excess water into basements slabs, foundation and retaining walls making them susceptible to water ingress through cracks, porous building materials, holes, joints and/or inadequate waterproofing.
