Description
Polythene Damp-Proof Membrane 1200g
100% recycled, 1200 gauge damp proof membrane for use below concrete floors or screeds where no groundwater pressure is expected. DampSafe 802-DPM is compatible with all common building materials, and suitable for numerous applications as a DPM, vapour barrier, or as a slip membrane, screeding membrane or curing membrane.
Key Benefits
- Easy to install as a loose-laid membrane.
- Resistant to elongation and tearing.
- Highly resistant to water vapour.
- Chemically inert (not affected by acids or alkalis in the ground).
- Suitable for most common floor construction.
- Quick and easy to join.
- Range of accessories for detailing around pipes, columns and other protrusions.
- 100% recycled.
DampSafe 802-DPM can also be sealed to DampSafe 809-HP DPC to extend the damp proofing through spine and exterior walls.
Typical Applications
- Loose-laid DPM below ground-bearing concrete slabs and rafts.
- Vapour barrier.
