Delta MS20 - Cavity Drainage Membrane

Delta MS20 is a high-density polyethylene (HDPE) dimpled sheeting with a high drainage capacity and compressive strength.

Features and benefits:

• A high-density, brown polyethylene (HDPE) drainage sheet with 20 mm-high dimples.
• The vertical drainage system combines high compressive strength with excellent drainage properties.
• May be installed as permanent shuttering either horizontally or 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.
• Delta dimpled sheets are rot-proof, resisting saline solutions, inorganic acids, alkalines, and polar liquids.
• They are proof against attack or modification by any of the minerals, humic acids, and bacterial catabolic products that naturally occur in the soil, as well as by bacteria, fungi, and micro-organisms.
• The response of all sheet types to soil or underground water is completely neutral, nor will they leach any harmful and/ or ecologically doubtful substances.
• Care should be taken to ensure that they are not permanently exposed to UV radiation.
