Delta-Drain installation instructions

Installation instructions for the Delta-DRAIN from Delta Membrane Systems give full details on the most effective method of fixing for this product range. Delta-DRAIN overcomes the potential problems that might occur with earth boundary construction elements such as foundation walls. It provides reliable surface drainage for cellar and retaining walls as well as roof gardens, by filtering out fine-grained soil particles, ensuring constant water drainage, and permanently protecting foundation walls. The installation instructions show how the dimpled sheet and the geotextile are installed so that they overlap at the edges, and are held in place using specifically designed Delta-HAFTNAGEL fixings which assist installation but do not replace the mecahnical fasteners applied from the outside.
