TUNNEL DRAINAGE
DELTA-MS 20
For use as a seeper course in double-skinned, horizontal or vertical constructions.
Material
Studded membrane made of special, high-density polyethylene. Is harmless to drinking water and cannot rot in the earth.
Properties
With its 20mm studs and high drainage capacity, DELTA-MS 20 is especially reliable. As ‘DELTA-MS 20 perforated’, this special membrane with the ability to drain large volumes of water is suitable for use on roof surfaces, such as car park decks, and for rooftop gardens.
Application
As residual formwork: DELTA-MS 20 can be used, saving you costs, between gunite installations or diaphragm walls and concrete masonry walls – either horizontally or vertically.
When laid vertically: The water emerging from the rocky substratum is drained off through a DELTA-MS 20 seeper layer.
When laid horizontally: Laid between the base slab and carriageway surface, DELTA-MS 20 absorbs the water that accumulates when the groundwater rises and channels it off to the drainage pipeline.
In tunnel construction: Its high drainage capacity enables it to meet all requirements for overcoming water problems on tunnel construction projects.
Allow to overlap by 20cm both lengthways and crossways.
