DELTA-Grundmauerschutz, Drainage und Abdichtung BASIS-QUALITÄT

DELTA-MS 20 – For use as a seeper course in double-skinned, horizontal or vertical constructions.

Application

DELTA®-MS 20 may be installed as a permanent shuttering in either horizontal or vertical runs between a shotcrete and/or curtain wall and the concrete wall or topping of a building. The dimpled sheet forms ahighly efficient surface drainage layer.

Attach DELTA®-MS 20 by mechanical means to the outer shell of a tunnel or the lining of an excavation. Take care to ensure that the dimples always point towards the outer shell. Sheets may be applied to the entire outer shell of the structure in a single run.

In vertical walls, one attachment point should be provided for each square metre of surface. On very rough surfaces, attachment points might have to be spaced more closely.

Material

Studded membrane made of special, high-density polyethylene.

Properties

  • The Solution for Subterranean Curtain Walls or Shotcrete Linings. DELTA®-MS 20 may be installed as permanent shuttering vertically between a shotcrete wall and/or curtain wall and the concrete wall of the building. In this case, the shotcrete acts as a filter, keeping the seepage layer free from soil particles.
