Description

A high-performance cavity drainage system membrane, suitable for use above and below ground on walls, floors and arched or vaulted ceilings as part of the SovDrain waterproofing system. The membrane has a thermally welded mesh on its face and is typically finished using directly applied Sovereign Whitewall Plaster, which is specifically designed for this application. Alternatively, dry lining can be used where plasterboards are fixed using the ‘dot and dab’ method.


Features and benefits:

  • Strong yet pliable.
  • Simple to form around corners.
  • Easily cut to shape and size using a knife or scissors.
  • Resistant to root penetration.
