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 and Sikalastic®-320 NS/SL 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 high flow dimpled polypropylene drainage core heat-bonded to a layer of non-woven polypropylene (420) or woven polypropylene (720) filter fabric on the top side and a polyethylene membrane protection film on the 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. Use the nonwoven filter fabric with soil, sand or stone ballast; use the woven filter fabric with freshly placed concrete or grout.
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 nonwoven polypropylene filter fabric on the top side and a heavy duty non-woven polypropylene membrane protection fabric on the bottom side. 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 bottom protection fabric provides cushioning for the waterproofing membrane. The geonet core is highly crush resistant yet flexible enough to conform to 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 vegetated roof assemblies consists of an impermeable dimpled polystyrene drainage core. The core is perforated, then bonded to a root resistant non-woven polypropylene filter fabric on the top side and nonwoven polypropylene membrane protection fabric on the bottom side. The filter fabric helps prevent roots from affecting the efficiency of the drainage/aeration layer as well as retaining soil or other fine particles from being washed away and allows water to pass into the drainage core. The bottom protection fabric provides cushioning for the waterproofing membrane. The core is installed dimpled side down to allow water retention within the cups. Excess water is collected and conveyed to a proper collection system, helping to control drainage flow.

Sika Drainage MatSafety Data Sheet
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.
Use
SikaBit® S-60 is ideal for waterproofing below grade concrete, masonry structures and wood surfaces where in-service temperatures will not exceed 130 °F (54 °C). It can also be applied to split slab construction both above and below grade as well as earth sheltered structures.
Characteristics and Advantages
- Waterproof membrane, high hydrostatic head resistance
- Easy to install, self-adhesive overlap ensures installation quality
- Controlled thickness, minimizes opportunity for job site error
- Flexible, handles shrinkage movement and minor settlement
- Cross-Laminated film, great stability and resistance to puncture and tearing
- Cold applied, no heat or flame necessary for installation
