STRATABASE SBS
Base Layer
SBS felts offers superior elasticity and excellent resistance to temperature fluctuations.
STRATABASE-SBS and STRATACAP-SBS consist of a special compound based on distilled bitumen modified with selected elastomers and reinforced with a non-woven spunbond polyester reinforcement, which offers good characteristics of mechanical resistance, ultimate elongation and dimensional stability. The SBS modified waterproofing compound assures good flexibility at low temperatures and excellent properties of elongation and resistance to roof movements.
Advantages
- Excellent mechanical resistance
- Good flexibility at low temperatures
- Excellent resistance to heat and UV rays
- Resistance to roof movements
- Suitable for residential and industrial applications
- Compatible with most roofing materials
Usage
- Residential and industrial waterproofing
- Compatible with most materials

Applications Back to top
The underside of STRATABASE-SBS and STRATACAP-SBS is finished with a thin thermofusible film, which easily melts upon torching, favouring a rapid and clean application. The upper side of the STRATACAP-SBS version is finished with a uniform layer of factory-applied natural or coloured slate chippings and is provided with a lateral selvedge for overlapping.
Surfaces must be perfectly dry, clean and sufficiently plain or levelled. Prior to adhering the membrane to the substrate, the latter must be primed with a quality bituminous primer. The product is welded down using a propane gas burner which burns off the underside film and melts down part of the bituminous undercoating. Overlaps have to be welded by torching with side laps of 8-10cm and end laps of 12-15 cm.
Stop installation in rain, snow, heavy fog or if the air temperature falls below +0°C .
