Newton DampSafe 802-DPM Polythene Damp-Proof Membrane (1200 Gauge)
The Newton DampSafe 802-DPM is a 100% recycled, 1200 gauge polythene damp-proof membrane designed for use below concrete floors and screeds where no groundwater pressure is present. It serves as an effective DPM, vapour barrier, slip membrane, screeding membrane, or curing membrane, ensuring long-term protection against moisture ingress.
Key Benefits
✔ Easy installation – Loose-laid for quick application.
✔ Tear-resistant & durable – High resistance to elongation & tearing.
✔ Effective moisture barrier – Prevents water vapour transmission.
✔ Chemically inert – Unaffected by ground acids or alkalis.
✔ Versatile – Compatible with most common floor constructions.
✔ Seamless integration – Can be sealed to DampSafe 809-HP DPC for continuous damp-proofing.
✔ Eco-friendly – Manufactured from 100% recycled materials.
Typical Applications
🔹 DPM for ground-bearing concrete slabs & rafts
🔹 Vapour barrier for flooring systems
🔹 Slip membrane between screeds & floors
🔹 Screeding membrane above insulation
🔹 Curing membrane for concrete slabs & rafts
Suitable Substrates
✅ Sand blinding
✅ Closed-cell insulation
✅ Newly placed concrete (as a curing membrane)
✅ Precast floors (as a slip membrane)
