What is DELTA® MS 20
DELTA® MS 20 is a dimpled drainage membrane for general-purpose seepage layer for long term safety.
- Foundation-wall protection
- Reliable drainage of water from double-shell structures in building and civil engineering
- Ideal for coping with water-related problems in tunnel constructions
- Compression-resistant and durable
- 20 mm dimples provides high drainage capacity
- Resists degradation in soil and chemical attack
- Non-polluting of drinking water
- Unaffected by saline solutions, acids, alkalines, oil, polar liquids and solvents
- Rot-proof
- Excellent temperature range from – 30°C to + 80°C
- Excellent resistance to puncture and decay
- Guaranteed against degradation for 20 years
- Can form a continuous cavity layer channelling water towards drains
- Excellent durability reduces future maintenance costs
- Offers outstanding safety thanks to its 20 mm dimples and high drainage capacity
- Can be used as cost-efficient permanent shuttering between a shotcrete shell or curtain wall and a concrete structural wall
- Drains off water emerging from surrounding rock when applied vertically
- Can catch rising underground water and convey it towards a drain
- Ideal for coping with water-related problems in tunnel construction
- Can form a continuous cavity layer channelling water towards drains
