Prefabricated and applied waterproofing membranes. From EPDM rubber to thermoplastic TPO, from bituminous sheets to bentonite geocomposites: the systems that make structures impermeable to water.
4 materials available
Bitumen-polymer ardesia sheet (APP or SBS). The definitive waterproofing for flat roofs and timber pitches. Torch-applied, double-layer system, cold flexibility from -5 to -20°C depending on mix.
EPDM: the synthetic rubber that replaced the torch. Elongation > 300%, durability > 50 years, cold-vulcanised seamless installation. The definitive flat roof membrane.
Sodium bentonite GCL geocomposite: the underground waterproofing that heals itself. Hydraulic permeability 1×10⁻¹¹ m/s. Self-healing capacity for cracks up to 2 mm. The only material that uses water against water.
TPO: hot-air welded thermoplastic membrane. SRI > 100 Cool Roof. No plasticisers, 100% recyclable. The white membrane that cuts air conditioning costs and boosts bifacial solar panels.
