Retaining Wall

Waterproofing Retaining Walls

A Retaining Wall is a structure designed and constructed to resist the lateral pressure of soil when there is a change in ground level. Principle pressures acting on a Retaining Wall come from the retained soil and from loading by ground and surface water where this water is not adequately drained.

A Retaining Wall may be independent of a building or structure, or it may form part of the general accommodation such as within a Lower Ground Floor, Semi-Basement, Basement or Cellar. Where buildings are constructed on a sloping site, changes in ground levels internally or externally may be dealt with by the construction of a Retaining Wall.

Protectahome are regularly asked to deal with Waterproofing Retaining Walls in addition to Structural Repairs to structures of the same nature. This page will cover our Waterproofing services, for more information on our Structural Repair Services for retaining walls click HERE.
