SBS Modified Bitumen Membrane.

Nonwoven  Polyester Reinforcement.


Highly elastic waterproofing membrane, torch applied, modified with Styrene Butadiene Styrene (SBS) to provide an extreme cold flexibility under severe cold weather, and reinforced with non-woven spunbonded polyester to insure exceptional strength for the membrane.

The nonwoven polyester reinforcement, ranging from 180 – 250 g/m², gives an exceptional strength for the membrane, the needed elongation and provides the membrane with the required resistance to heat ageing, puncture, and rotting.

The upper face is covered with polyethylene film, or colored slates.

Field of Application:

Due to its very  low cold pliability, SPY is used in areas where severe weathering conditions are expected such as: 

  • Roofs (reinforced concrete, prefabricated concrete, metal and timber deck).
  • Multi-story car parks.
  • Underground foundations, basements, and retaining walls.
  • Reservoirs, basins and canals.
  • Swimming pools.

Technical Specifications:

Dimensions 1×10 m Roll
Thickness: 4 or 5mm
Cold Pliability: no cracking at (-15) – (-20) ºC
Softening Point: ≥130
