PRODUCT DESCRIPTION      
Pre laid self-adhesive waterproofing membrane is a self-adhesive waterproofing membrane made of polyester fiber felt or polymer material as the base material, coated with self-adhesive modified asphalt on both sides, coated with special bonding adhesive on the upper surface, covered with isolation materials such as polyethylene film and polyester film on the lower surface, and coated with silicon isolation film or silicon isolation paper on the upper surface as isolation materials. It is suitable for pre laid anti adhesive construction.

PRODUCT FEATURES

▪ Low requirements for the base surface, construction can be carried out on damp base layers.
▪ The roll material is bonded to the post poured concrete as a whole, and even under long-term immersion in water, it is inseparable, making the waterproof performance more solid.
▪ Cold construction, short construction period, and low cost.
▪ High tensile strength, high elongation, puncture resistance, and strong corrosion resistance.
▪ Pre laid waterproof rolls are mostly single-sided self-adhesive, with high strength and high extensibility, effectively avoiding damage to the waterproof layer caused by structural expansion and displacement of buildings. They have excellent water resistance and effectively solve the problems in underground waterproofing.

Advantages of pre laid self-adhesive waterproofing membrane: reliable quality, cost saving, easy operation, environmental protection, and energy saving

Excellent cost performance - can bond with uncured cement, saving leveling layer and bottom protection layer, and together with the structure, build an extraordinary "skin" type strong waterproof system with high reliability.
Pre laid bonding can be integrated with the subsequently poured concrete, and it remains inseparable even after long-term immersion. This function solves the problem of pre laying (external anti sticking) waterproofing. Low requirements for base surface, saving construction time. Construction can be carried out on damp or even ungraded base surfaces without the need for primer, and the construction freedom is high. Not affected by weather, the advantage is more prominent during rainy season construction. It can be integrated with waterproof coatings, with complementary advantages. The surface can be integrated with later applied waterproof coatings, thus solving problems such as pipe penetration, closure, and overlap. The advantages of coil and coating complement each other, achieving seamless operation and reliable bonding of coil, making it easy to maintain the firm and long-lasting bonding between coil and structure. If there is any local damage to the roll material, the water will be limited to a very small range, without water leakage or seepage. Even if there is leakage in the weak points of the waterproof layer and structural cracks, it is easy to repair.
The cement slurry used for both rigid and flexible wet paving achieves a cover type water retention curing. The initial setting, final setting, and the subsequent critical hydration process are all completed in an ideal environment, and its strength, compactness, and crack resistance are greatly superior to those of water curing cement slurry, which can serve as a rigid waterproof layer.
Environmental protection and energy conservation - no solvents or fuels are used during the construction process, avoiding environmental pollution and fire hazards, and promoting energy conservation and environmental protection.
