DELTA®-NP DRAIN

DELTA®-NP DRAIN

DELTA®-NP Drain for the protection of the waterproofing of building structures (DIN 18 195 Part 10) and/or surface drainage (DIN 4095).

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.

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.
