Oldroyd Cavity Drainage Membranes
Oldroyd cavity drainage membranes are dimpled membranes that are designed to provide a dry basement environment by diverting water rather than physically holding it back. On externally waterproofed basements, Oldroyd membranes are typically used as a secondary drainage layer to provide additional protection for the primary waterproofing system (e.g. Vandex Super or Vandex BB75E). When used internally, Oldroyd membranes are applied to walls and floors to redirect any water entering the basement to a sump and pump. For further details see our cellar conversion and newbuild basement pages.
Aquadrain drainage channel is laid around the floor-wall junction as part of an internally-applied cavity drainage system. This provides additional drainage capacity where the basement is most vulnerable to water ingress.
Safeguard sump systems are pumping solutions specifically designed for use with Oldroyd cavity drainage membranes in basement waterproofing applications.
