Description
An internally applied, composite damp proof membrane comprising of either 803 - 3mm HDPE or 805 - 5mm HDPP membranes with a rot-proof polythene mesh that is heat welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.
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.
- Quick and easy to install.
- No need to use injected damp-proof courses which unnecessarily pump chemicals into the property.
- Completely moisture resistant but allows vapour diffusion.
- 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.
