◇Product Introduction
Pidibond BAC-P Black Diamond Self-Adhesive Waterproofing Membrane is a pre-applied self-adhesive waterproofing membrane composed of a high-performance polymer film, a high-performance self-adhesive rubberized asphalt compound, a black anti-adhesion layer, and a silicone-coated release film. This membrane exhibits excellent physical properties, high peel strength to post-cast concrete, and superior application performance. It is suitable for waterproofing projects in basement slabs, basement side walls with exterior waterproofing applied to the interior side, subways, tunnels, and other pre-applied areas. It can be combined with other self-adhesive modified asphalt waterproofing membranes to form a dual-layer waterproofing system.
◇Product Features
● Pre-applied bonding for excellent waterproofing performance. It can bond reversely with post-cast concrete to form an integrated whole, remaining inseparable even under prolonged immersion, delivering outstanding waterproofing results.
● Reliable bonding for easy maintenance. The membrane can bond durably and firmly with the structural layer. Even if the membrane is locally damaged, water is confined to the point of damage in the waterproofing layer without lateral migration.
● Soft and conformable for good workability. The membrane is thin, light, and flexible, offering excellent adaptability to complex details, better conformity to the substrate, and simple, convenient installation.
● Black anti-adhesion layer enhances mechanical performance. The anti-adhesion layer on the upper surface effectively prevents UV damage to the self-adhesive layer during construction, and generates a continuous interlocking reaction with post-cast concrete, improving bond strength, peel performance, and water-blocking performance.
● Unique back-side self-adhesion for excellent composite performance. After removing the release film on the back side, the membrane exhibits self-adhesive properties, enabling "adhesive-to-adhesive" bonding with other self-adhesive modified asphalt waterproofing membranes. With good compatibility, the waterproofing layer achieves greater integrity, enhancing system reliability and meeting the Grade I protection standard.
● Cold self-adhesive application for safety and environmental friendliness. The membrane is applied using cold self-adhesive methods, requiring no primer or open-flame torching, making it safer and more environmentally friendly.
