What is Basement Tanking/Waterproofing?

When a property or part of a property is at ground level or below, basement waterproofing is essential. A build-up of water/moisture in the ground surrounding the basement, raising the water table, causes hydrostatic water pressure. This water pressure is exerted on the floor and walls of the basement and will result in water penetration through fractures, joints and structural weak points in the basement.

Without basement waterproofing, this water ingress can then result in mould, decay, structural issues and other damp-related issues. Sealing structures below ground to prevent water ingress can be a genuine challenge. Increasing property prices and the need to make use of existing space have likewise resulted in an increased demand for reputable tanking systems for basements and other underground structures, many of which were not originally developed for habitation.

Southern Damp Proofing’s basement tanking systems help to maintain dry environments which can then be successfully insulated to meet existing building regulations. A basement tanking membrane can be utilized to speed up the drying of flood-damaged properties. Our damp proof membrane offers an outstanding primary waterproofing system when used with a cavity drainage membrane.
