Waterproof self-adhesive bituminous tapes, made of bitumen-elastomer compounds and protected by reinforced aluminum metal foil. The reinforced aluminum foil that covers the belts guarantees safe and reliable work over time, as it protects the belt compound from all factors that could compromise its integrity, such as gas, light or UV rays. The BIT-TAPE allow repairs and waterproofing that have a prolonged duration: their effectiveness, in fact, decreases only when the protective sheet is completely consumed by oxidative processes.
