What is the benefit of a Mineral Surface finish?

Mineral (slate) flakes provide a decorative finish and, more importantly, shield the bitumen from UV degradation, eliminating the need for a reflective coating.

Can these membranes be used for "Green Roof" applications?

es. We supply specialized Anti-Root APP/SBS membranes treated with chemical additives that prevent root penetration without damaging the plants.

What is the difference between Polyester and Fiberglass reinforcement?

Polyester offers high mechanical strength and elongation (better for movement), while Fiberglass provides excellent dimensional stability (better for preventing shrinkage).

What is the difference between torch-applied and self-adhesive waterproof membranes?

Torch-applied membranes require heat from a gas torch to activate the bitumen layer, ensuring a strong bond to the substrate and making them ideal for large-scale roofing and heavy-duty applications. Self-adhesive membranes, on the other hand, come with a pre-applied adhesive layer protected by a release film, allowing installation without heat. These are preferred ffor confined spaces, indoor applications, or projects where open flames are restricted for safety reasons.

How long do APP and SBS waterproof membranes last?

The lifespan of APP and SBS modified bitumen membranes typically ranges from 15 to 25 years when properly installed and maintained. APP membranes tend to perform exceptionally well in high UV and heat exposure environments, while SBS membranes offer superior flexibility and durability in areas subject to thermal movement or colder climates. Proper substrate preparation, correct installation, and periodic inspection are key factors influencing long-term performance.

Are waterproof membranes resistant to chemicals and environmental exposure?

Yes, high-quality bituminous waterproof membranes are engineered to resist a wide range of environmental and chemical exposures, including acids, alkalis, and salts commonly found in soil and groundwater. APP membranes offer enhanced resistance to UV radiation and oxidation, while SBS membranes provide flexibility and resistance to cracking under structural movement. Specialized variants are also available for aggressive industrial environments and contaminated soil conditions.

Can waterproof membranes be installed on existing roofs?

Waterproof membranes can often be installed over existing roofing systems, provided the substrate is structurally sound, clean, and properly prepared. In refurbishment projects, a primer layer is typically applied to improve adhesion, followed by the installation of the new membrane system. This approach reduces demolition costs and project downtime while extending the service life of the roof.
