◇ Product Introduction
The MAC Non-Asphalt-Based Polymer (TPO) Self-Adhesive Membrane Waterproofing Sheet is a high-performance composite waterproofing material, consisting of a lower polymer (TPO) sheet, butyl adhesive, and an upper anti-stick release layer. This membrane combines the advantages of both polymer membranes and self-adhesive membranes, featuring excellent tensile performance, high elongation, low dimensional change rate, and good low-temperature flexibility. The product offers stable performance and reliable quality.
◇ Product Features
● Pre-laid bonding: It can bond with subsequently poured concrete to form an integrated whole, remaining inseparable from the structure even under prolonged underwater immersion, solving the waterproofing challenges of pre-laid (external waterproofing with internal application) construction.
● Reliable bonding, easy maintenance: The waterproofing membrane bonds tightly with the post-poured concrete. Should any localized damage occur to the membrane, water will be confined to a very small area without migration. Even if individual leakage points appear, they will coincide with the damage points, making maintenance extremely easy.
● Low substrate requirements, shortened construction period: It can be applied on damp or even unleveled substrates without the need for primer. The high construction flexibility is unaffected by weather conditions, with even greater advantages during rainy-season construction, making it the most powerful "tool" 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, elongation, and strong adaptability to structural deformation.
● Long service life: Resistant to acid, alkali, and salt corrosion.
● Optimal cost-effectiveness: It can work together with the post-poured concrete structural layer to create an exceptional "skin-type" robust waterproofing system with high reliability, while eliminating the need for traditional cement mortar leveling layers and fine-aggregate concrete protective layers, reducing overall costs and lowering system expenses.
