Loose-laid and mechanically fastened protection and drainage sheet for:

  • Preformed sheet membrane waterproofing systems.
  • Liquid-applied membranes.
  • Sika® White Box concept for waterproofing retaining walls and heavy-duty roofs and podiums.

Description

Heavy-duty, 10-mm, dimpled drainage and protection sheet made from high-density polyethylene (HDPE) with a polypropylene (PP) geotextile filtration layer bonded to the top.

Benefits:

  • High drainage capacity.
  • Integral filtration layer.
  • High mechanical and impact resistance.
  • Resistant to all natural aggressive mediums in ground water and soil.
  • Can be installed on damp and wet substrates.
  • Suitable for contact with soft water (aggressive to concrete).
  • The sheet forms a drainage channel in the space between the structural elements and the substrate to allow water to drain away.

Applications:

Loose-laid and mechanically fastened protection and drainage sheet for:

  • Preformed sheet membrane waterproofing systems.
  • Liquid-applied membranes.
  • Sika® White Box concept for waterproofing retaining walls and heavy-duty roofs and podiums.

Approvals:

  • Manufactured under ISO 9001 and ISO 14001-certified 'Quality and Environmental Systems'.
  • Occupational Health & Safety Management OHSAS 18001.
  • Manufactured in accordance with BS EN 13252.
