Verified by manufacturer 6 months ago
Heavy-duty drainage and protection sheet.
Application
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.
Feature and 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.
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.
