◇ Product Introduction
MAC Non-Asphalt-Based Polymer Self-Adhesive Membrane Waterproofing Sheet is a high-performance composite waterproofing material specifically developed for pre-applied waterproofing applications in building construction. It consists of a polymer sheet, a polymer self-adhesive layer (non-asphalt-based), and a granular layer. This waterproofing membrane can bond tightly with subsequently poured concrete, eliminating the water channeling layer between the membrane and the structural layer, forming a reliable "skin-type" waterproofing system.
◇ Product Features
● Pre-applied bonding: It can bond with subsequently poured concrete as an integrated whole, remaining inseparable from the structure even after prolonged immersion in water, solving the waterproofing challenges in pre-applied (external waterproofing with internal application) construction.
● Reliable bonding, easy maintenance: The waterproofing membrane bonds tightly with subsequently poured concrete. Should any localized damage occur to the membrane, water will be confined to a very small area without channeling. Even if individual leakage points occur, they will align with the damaged points, making repair extremely easy.
● Low substrate requirements, shortened construction period: Installation is possible on damp or even unleveled substrates without the need for primer. The high flexibility of installation is unaffected by weather conditions, and the advantages are even more pronounced during rainy-season construction, making it the most powerful "weapon" for ensuring project schedules.
● Safe and environmentally friendly: No solvents or fuels are required during installation, and no open flames are used, avoiding environmental pollution, eliminating fire hazards, and conserving resources.
● Excellent physical properties: Superior tensile strength and elongation, with strong adaptability to structural deformation.
● Optimal cost-effectiveness: It works together with the subsequently poured concrete structural layer to form an exceptionally reliable "skin-type" waterproofing system with high reliability. It also eliminates the need for traditional cement mortar leveling layers and fine aggregate concrete protective layers, reducing overall costs and lowering system expenses.
