DELTA® - MS 20 Cavity Drainage Membrane


Profiled membrane with 20 mm projections for organizing vertical and horizontal reservoir drainage in underground and vertical structures.

Tried and tested pressure-resistant dimpled sheet made of HDPE with a 20 mm high dimple structure for use as a high-performance seepage layer in double-shell structures in building construction, underground construction, and construction engineering.

Advantages

  • Very good resistance
    DELTA®-MS 20 is resistant to chemical and microbiological pollution. Thanks to its resistance to rotting, it offers a material durability in the installed state of a minimum of 25 years. In addition, the sheet is safe for drinking water.
  • High drainage capacity
    Thanks to its dimple height of 20 mm, the dimpled sheet offers a very high drainage capacity for both vertical and horizontal applications.
  • Controlled water drainage when securing the excavation by installation
    The product DELTA®-MS 20 enables the efficient installation of an extremely high-performance seepage layer with different construction techniques. In this manner, the water occurring during and after the construction work is (temporarily) drained away in a pressure-relieved way.
  • Reliable drainage of water in tunnel construction projects
    Arranged between shotcrete or adjacent rock and the inner shell, the product DELTA®-MS 20 significantly reduces the load from crevices, strata, or seeping surface water in case of small overlaps. The 20 mm high seepage layer also creates runoff reserves, for example in the event of higher seasonal water incidence (snow melt), but also in case of a cross-section narrowing caused by the sintering over the years.

Application

The product DELTA®-MS 20 can be used as a high-performance seepage layer in double-shell structures in building construction, underground construction, and construction engineering.
