CAC®-POWERSHIELD BM SBS

For many years, box-type waterproofing in basements relied on the traditional stone-and-cement slurry system. While it served as a basic barrier against water ingress, modern construction environments have exposed its critical limitations. This system cannot withstand deformation in concrete. Large RCC members with high concrete volumes demand specialized treatment. It is also difficult to execute in confined basement spaces.

These factors make the system challenging to apply consistently on large infrastructure projects and increase the risk of waterproofing failures.
With today’s fast-paced construction schedules and complex structural designs, waterproofing systems must deliver speed, reliability, and long-term durability.

CAC®-POWERSHIELD BM SBS
A self-adhesive bituminous membrane, factory-manufactured to deliver a consistent thickness of 1.5 mm, ensuring uniform performance, flexibility, and impermeable protection for concrete basement structures.

Designed with an elastomeric modified bitumen compound and a robust rot-proof core, the membrane provides rubber-like flexibility and durable waterproofing performance even in constantly wet environments.
Key Benefits
▪️ Flexible membrane with elastomeric SBS modification
▪️ High tensile strength and elongation for durability
▪️ Excellent resistance to hydrostatic water pressure
▪️ Seamless lap joints ensuring adhesion and continuity
▪️ Reliable performance in permanently wet environments
▪️ Factory-controlled thickness and consistent quality
▪️ Faster application compared to conventional methods

Applications
Foundation walls, raft foundations, pile caps, tie beams, basements, wet areas, under-tile waterproofing, sewerage manholes, and as a vapour barrier — wherever structures require robust waterproofing under hydrostatic pressure.

Waterproofing is not just about stopping water.
It’s about protecting structural integrity where water pressure is constant and unforgiving.
