DELTA 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. DELTA dimpled sheeting cannot be damaged or affected either by minerals, humic acid, or bacterial decomposition in the earth, nor can bacteria, fungi and microorganisms 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 DELTA 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 fabric filter prevents ground particles from floating into the drainage layer. A thermic-welded layer allows dimpled sheeting to be used as the base for shotcrete or mortar.

DELTA®-DRAIN:
Brawn dimpled sheeting with geotextile; constant pressure and filtration characteristics

DELTA®-PT:
With dimpled sheeting with thermic-welded plastic mesh

Service Life of Over Half a Century.
DELTA-MS is manufactured exclusively from a specially selected polyethylene grade with field-proven physical and chemical properties. Special stabilizers incorporated in the material ensure an expected service life of at least 50 years in underground applications (as documented by Sweden's SPF environmental ageing test).

DELTA®-GEO-DRAIN/DELTA®-GEO-DRAIN TP:
Brown dimpled sheeting with high compressive strength and geotextile, providing a rugged filter (for placing on thick layers with separating membrane)

DELTA-MS is the only foundation wall protection sheet made in Germany which has passed this rigourous test procedure.
