Post-applied Self-adhered Membrane (SikaBit)
Sika® Drainage Mat
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.
Use
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.

Sika Drainage MatsSikaBit® S-60
SikaBit® S-60 is a proprietary composite, uniquely designed to provide high strength, low temperature adhesion and high temperature stability in a superior waterproofing membrane. A tough cross-laminated film forms a resilient barrier against physical damage and water migration. It is a cold applied system requiring no heat or special equipment to install. SikaBit® S-60 is ideal for waterproofing below grade concrete, masonry structures and wood surfaces where in-service temperatures will not exceed 130°F. It can also be applied to split slab construction both above and below grade as well as earth sheltered structures.
