Waterproofing Membrane Accessories
Sarnafelt is a leveling and/or a separation layer provided for use within Sika Sarnafil roofing systems. Sarnafelt is composed of non-woven unsaturated polyester.
Sika Drainage Mats
Sika Drainage Mat composites are available in both high flow dimpled core and high crush resistant geonet constructions. They perform a multi-faceted role by providing protection for RoofPro membranes as well as a means of collecting and conveying excess water in plaza decks, split slabs, planters, roof gardens and other roofing and waterproofing applications.
Sika Drainage Mat 420 and 720: Sika Drainage Mat 420 and 720 consist of an impermeable polypropylene sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is then heat bonded to a layer of nonwoven (420) or woven (720) filter fabric on top side and membrane protective film on bottom side. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core.
Sika Drainage Mat 1000: Sika Drainage Mat 1000 consists of a high density polyethylene geonet drainage core with its ridges heat fused to a layer of filter fabric on both sides. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass through to the core. The back side layer of heavy duty fabric provides protection and cushioning for the waterproofing membrane. The geonet core is highly crush resistant yet flexible enough to conform irregular surfaces. Sika Drainage Mat 1000 is suitable for heavy loads and split slabs exposed to vehicular traffic.
Sika Drainage Mat GRS: Sika Drainage Mat GRS for green roofs consists of a polymeric sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is perforated, then bonded to a 100% post-consumer recycled polyester filter fabric on top and protection fabric on bottom. The top filter fabric helps prevent roots from affecting the efficiency of the drainage/aeration layer as well as retains soil or other fine particles from being washed away and allows water to pass into the drainage core. The bottom protection fabric safeguards the waterproofing membrane. The core is installed dimpled side down to allow water retention. Excess water is collected and conveyed to a proper collection system.

Sarnafelt NWP Seperation Layer
Sarnafelt NWP Separation Layer is a high quality geotextile fabric of non-woven polypropylene. Sarnafelt NWP Separation Layer is installed between the waterproofing membrane and the extruded polystyrene (XPS) insulation. It can also be used between the waterproofing membrane and protection layers. It is intended to act as separation between products and also to increase the puncture resistance of the waterproofing assembly.
