Key Benefits
  • Provides a surface that is totally separated and unaffected by the dampness within the wall ensuring that the wall finish will never be affected by moisture or salts
  • Superb ‘key’ for renders or plasters
  • No need to use injected damp-proof courses which unnecessarily pump chemicals into the property
  • Completely moisture resistant but allows vapour diffusion
  • Quick and easy to install
  • In many cases, the existing render can be left on the wall
  • No requirement for damaging preparation to the wall surface
Typical Applications
  • As a damp-proof base for renders, plasters or dot & dab plasterboard
  • As a damp-proofing system to deal with rising damp
  • To protect exposed elevations against wind-driven rain
  • An extenal plaster base for timber frame structures

BBA-Certificate-Newton-Cavity-Drain-MembranesNewtonite presents a physical barrier between the old surface and the new internal finish. Unlike many systems it can be punctured when new wall fixings are required. Even poor and random substrates can easily receive Newtonite.
