Damp Proof Membrane 4mm

Sunny Ebere safety and tools enterprise. Damp proofing is defined by the American Society for Testing and Materials (ASTM) as a material that resists the passage of water with no hydrostatic pressure.[1] Waterproof is defined by the ASTM as a treatment that resists the passage of water under pressure.[1] Generally, damp proofing keeps moisture out of a building, where vapor barriers keep interior moisture from getting into walls. Moisture resistance is not necessarily absolute; it is usually defined by a specific test method, limits, and engineering tolerances. DampSafe 802-DPM 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 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.
