Delta MS Brochure Delta PT Brochure
Dörken Delta MS and PT dimpled sheeting is manufactured from environmentally friendly, long-lasting, and resistant special polyethylene.
It provides a highly effective and efficient seepage and drainage layer in all areas of construction. It is pressure resistant, rotproof, and resistant to saline solutions, inorganic acids, alkalis, and liquids such as alcohols, organic acids, esters, ketones and similar substances.
Dörken Delta MS and PT dimpled sheeting cannot be damaged or affected either by minerals, humic acid, or bacterial decomposition in the earth nor can bacteria, fungi and micro-organisms attack it. In regard to both the soil and the groundwater, the dimpled sheeting remains completely inert and does not give off any damaging or environmentally hazardous substances.
In the laying of Dörken Delta MS and PT dimpled sheeting any health risk can be completely excluded. Different stud heights make sure that water can drain away properly in horizontal or vertical seepage layers.
A filter fabric prevents ground particles from floating into the drainage layer and a thermic-welded layer allows dimpled sheeting to be used as the base for shotcrete or mortar.
