Characteristics of non asphalt self-adhesive waterproofing membrane

Non asphalt based self-adhesive waterproofing membrane is a type of waterproofing membrane specifically developed for underground and tunnel engineering. It can be pre poured and then poured into concrete structures to form a sturdy anti adhesive waterproofing membrane. This film is a polymer self-adhesive waterproof film mainly made of resin polymers (EVA, LDPE, HDPE, ECB, etc.), as well as a polymer waterproof substrate covered with a self-adhesive film. The self-adhesive layer of the coiled material and the protective layer against environmental changes have self-healing function. After reacting and solidifying with liquid concrete slurry, non asphalt self-adhesive waterproofing membrane forms a seamless bond between the waterproof layer and the concrete structure, preventing the hidden danger of water seepage and effectively providing the reliability of the waterproofing system.
Characteristics of non asphalt self-adhesive waterproofing membrane:
1. Unique formula, non asphalt based reactive pre-set polymer self-adhesive membrane, is made of non asphalt based self-adhesive and polymer sheet.
2. Polymer self-adhesive film (non asphalt based) waterproof film has unique adhesive properties, with a peel strength 2-3 times that of ordinary self-adhesive film.
3. High tear resistance, waterproof and anti-seepage, strong hydrolysis resistance.
4. Good low-temperature flexibility, can maintain good flexibility when thrown at -30 ° C.
5. Non asphalt self-adhesive waterproofing membrane is suitable for pre laying and anti adhesive waterproofing projects in underground and tunnel engineering. After the completion of the waterproof layer construction, it has the impact resistance of directly bonding steel bars and pouring concrete without protective layer.
6. The waterproof performance is reliable, and the coil combines the advantages of polymer waterproof coils and self-adhesive coils.
7. Low requirements for base surface, saving construction time, no need to level the base surface with cement mortar, and can be constructed on wet base surface; No need for base treatment, unaffected by weather, saving construction time and reducing project costs.
8. The construction is simple and fast, and the construction methods are flexible and diverse. According to actual needs, wide coils can be produced to reduce overlap, facilitate rapid construction, lower energy consumption, and lower costs. During the construction period, construction methods such as empty paving and mechanical fixation can be selected according to the site conditions of the project. The construction methods are more flexible and the waterproof effect is better.
9. Green and environmentally friendly, no solvents or fuels are required during the construction process, avoiding the fire hazards of environmental pollution and saving energy.
10. Non asphalt self-adhesive waterproofing membrane and base layer are empty and not affected by base layer settlement and deformation.
