Bituminous, EPDM and PVC sheets

Bitumen, EPDM and PVC membranes offer the highest level of technical performance in protecting structures against water ingress and persistent damp in roofs and walls. Designed to provide a continuous waterproof barrier, these solutions guarantee long-lasting watertightness in both residential builds and demanding industrial projects.

Waterproofing solutions using bituminous membranes, EPDM and PVC

The range of bituminous, EPDM and PVC membranes stands out for its compositional versatility and excellent weather resistance on any surface. Formulated with bituminous binders, synthetic polymers or elastic rubber, these membranes accommodate structural expansion and contraction, preventing cracks and deformations that could compromise the building’s waterproofing.

The bituminous models in the range incorporate internal reinforcement made of fibreglass or polyester felt, significantly increasing their puncture resistance. With surface finishes ranging from standard polyethylene film to mineral granule protection or aluminium-coated sheets, this variety allows the system to be adapted for walkable or exposed roofs.

Meanwhile, the synthetic options in calendered PVC and EPDM membranes offer extreme durability against UV rays and adverse temperatures. Their high flexibility facilitates the installation of complex junctions, valleys or unique features on flat and pitched roofs, ensuring a clean finish and sustained performance over time.

Technical advantages of the range of waterproofing membranes

• High mechanical resistance to puncture and stresses from the substrate.
• Membranes with an aluminium finish or self-protective mineral coating in grey and red slate.
• A complete range of bituminous emulsions for preparing primer coats.
• Excellent thermal stability against extreme frost and direct sunlight.
• Fully compatible with green roof systems, terraces and underground walls.

Criteria for choosing the right roofing membrane

When selecting the right membrane for your project, you should assess the intended use of the surface, the pitch and exposure to the elements. If you are looking for a traditional, high-strength solution for walkable or underground terraces, LBM rolls with SBS- or APP-modified bitumen offer optimum adhesion through flame-welding.

For projects where weight reduction is required or to ensure a long service life with minimal maintenance, synthetic PVC membranes and elastic waterproofing systems are a strategic choice. Assess the requirements of your substrate, combine the membrane with primer emulsions from the range, and ensure a flawless, long-lasting seal on your project.
