Application

The fastening is regarded as assembly aid and is always placed
above the water proofing. The top edge must be about 10 cm
higher than the water proofing.

At the bottom the sheet stops tight against the drainage pipe. The drainage pipe is surrounded with at least 15 cm of filter material.

After backfilling, the sheet is cut off at ground level. Then the
DELTA-NOPPENBAHNEN PROFILE is fixed.

With overlapping, the connecting sheet is always pushed under the lifted edge of the geotextile. Remove the protective strip and bond the adjoining sheet sections together.

Plastic light-shafts should be fixed directly on the sheet. Cut out the window openings later.

Material

A studded membrane made of special, high-density polyethylene and high quality PP geotextile.

Properties

Cost-efficient and Highly Reliable.
With its special filtration cloth, this dimpled sheet features an outstanding compressive strength of about 150 kN/m2, acting as a reliable drainage system incivil engineering, supporting walls of all type.
