SBS Waterproofing Membrane System

Self‑adhesive SBS modified bituminous membranes for roofs and below‑grade

SBS modified bituminous membranes reinforced with polyester/hybrid fleece, offering flexibility, high watertightness, and strong puncture resistance—installed as cold‑applied self‑adhesive sheets with protected laps.

Hydrostatic head: 5 bar (50 m)

Peel adhesion to primed concrete

High puncture resistance

Cold‑applied self‑adhesive

Flexible, Watertight Membranes for Roofs and Ground Contact

Roofs, basements, retaining walls, and similar structures need waterproofing that tolerates temperature variation and movement while maintaining watertightness.
SBS modified membranes deliver this through enhanced flexibility, reinforced strength, and controlled thickness—supporting durable sealing when installed per the system method.

How Self‑Adhesive SBS Membranes Are Applied

Concrete is checked for hollowness and repaired using polymer‑modified mortar, then cured for at least 72 hours; surfaces are cleaned of dust and contaminants.
A bitumen primer is applied to promote adhesion, allowed to dry, then the release film is peeled and the membrane is unrolled and pressed from center to edges to remove air.
Overlaps are maintained (side laps typically 50–75 mm; end laps 100 mm), and an iron roller is used to ensure strong bonding.
After installation, exposed areas are finished with aluminum paint for non‑foot traffic or protected with a cement screed on trafficked zones or where protection is required.
