Bitumen waterproofing P-ro Lybra 4kg without sprinkling GENERAL MEMBRANE

LYBRA P elastomeric bitumen waterproofing membranes are made from high-quality distilled bitumen, modified with special thermoplastic polymers - styrene-butadiene-styrene (SBS) and a selectively selected stabilizing filler. The specific SBS formula guarantees exceptional elasticity, resistance to thermal aging and prevents the appearance of cracks in the waterproofing system. The product functions perfectly at low temperatures in cold climate zones and withstands serious structural loads and deformations.

To achieve maximum mechanical strength and dimensional stability, the reinforcement of LYBRA P membranes consists of a composite non-woven polyester, longitudinally stabilized with reinforced glass fiber threads. This composition provides excellent isotropic behavior and prevents shrinkage or wrinkling of the insulation. As the finishing top layer is made of quartz sand, surface protection (mineral spread, gravel ballast or screed) is recommended when used as a finishing top layer to avoid direct damage to the bitumen by UV rays.

Purpose

• Construction of lower, intermediate or underlayment layers in multi-layer roofing systems
• Waterproofing of flat roofs of buildings subjected to serious loads
• Waterproofing of underground facilities, foundations, foundations and metal structures
• Ideal for installation in regions with large temperature amplitudes and cold climate conditions

Main advantages

• Excellent cold resistance: Remains flexible at temperatures down to -15°C, facilitating installation in winter
• Superior elasticity: Elastomeric bitumen stretches and absorbs building movements without tearing
• Exceptional strength: Composite polyester braid offers high tear and perforation resistance
• Perfect stability: Fiberglass reinforcement guarantees zero dimensional deformation
• Easy and safe processing: Gas flame welding with optimal bitumen melting
