Henkel Polybit Rooftite S20

Rooftite S20, based on self-adhesive membrane technology, is the optimum solution for a long-lasting waterproofing protection of concrete roofs from water leakages and vapor ingress. The system comprises of a self-adhesive membrane and a geotextile fleece surfaced bituminous membrane. The heat insulation of the building may be improved significantly, using suitable built up systems - e.g.: EPS boards and tiling of white colour.

Fields of application:

– buildings and villas

– RCC/ inverted roofs

– accessible roofs

Characteristics:
- Resistance to puncture and impact
- Tough and durable
- Self-healing capability against minor punctures
- High resistance against water and vapor
- Heat insulation achievable with built up system
Components:
1. Polyprime SB: Quick drying solvent based low viscosity bitumen primer. Conforms to ASTM D41, with a solid content of at least 40%.
2. Bitustick XL: a self adhesive waterproofing membrane based on a tropical grade of polymer modified bitumen. The bitumen compound is laminated onto an impervious, non-perforated, cross laminated HDPE film.
3. Bistustick R300: a bituminous self adhesive membrane laminated onto a tough geo-textile fleece. The membrane is specially designed to provide a high level of protection for waterproofing membranes applied on underground concrete structures against mechanical loads and pressure.
4. Bitutape TS: a non-reinforced twin side adhesive bitumen membrane which comprises of polymerized bitumen sandwiched between a plastic release film on either side.
