Self-adhesive pre-coated polymer film waterproofing membrane Product Description First, self-adhesive pre-coated polymer film waterproofing membrane is designed for an underground and tunnel project developed with the pre-shop after pouring the concrete structure to form a solid anti-stick Results of the waterproofing membrane. The membrane based resin, polyethylene polymer (EVA, LDPE, HDPE, ECB, etc.) as a main component of the sheet of waterproof material, waterproof polymer in the non-coated substrate plus asphalt-based self-adhesive rubber polymer material waterproofing membrane. After the reaction, the reaction layer self-adhesive membrane with liquid concrete consolidation Masonry materials, which form the base layer and a waterproof concrete structure combined with gapless prevent interlayer channeling water leakage problems, can effectively improve the strong resistance and waterproofing system reliability , security, green nature. ? Second, the product features a polymer film self-adhesive waterproofing membrane pre-shop the unique formula, using self-adhesive plastic and polymer composite materials incorporated into; combined with excellent adhesive properties, from the strength of ordinary self-adhesive roll 3-4 times material; high tear strength, water impermeability, high hydrolysis resistance. 2, low temperature flexibility is good, at -28 degrees below conditions continue to have a good anti-low temperature flexibility. 3, for other underground, underwater engineering and tunnel leak pre-coated anti-stick waterproofing with a waterproof layer construction after the completion of the steps directly without protective layer steel banding, with pouring concrete impact resistance. 4, waterproof performance, reliable, waterproof membrane with both advantages and self-adhesive waterproofing membrane reaction; base surface is low, saving time limit, no cement mortar grassroots polished surface, wet surface was grass roots are constructability; no need to carry out under the paint and primary treatment, protected from the weather, which can save time limit, reduce project cost. 5, the construction simple and quick, flexible labor laws, the construction can choose to empty shop project site based on favorable conditions, mechanical fixing and other construction methods. 6, green, safety, environmental, construction process without solvent and fuel, to avoid environmental pollution and fire hazards, saving energy; waterproofing membrane and primary empty shop without SETTLEMENT affect the grassroots level. ? Third, the scope 1, traffic engineering: subway, tunnel, cave, bridges and other waterproof, anti-seepage project 2 Construction: roofing, basement, ground floor three other water projects, water projects: Reservoir dam, cofferdam, canals, artificial lake water, seepage 4, Environmental Engineering: garbage fill the field, sewage treatment plants, metallurgy, chemical plants and other water seepage works fine Fourth, the construction of highway tunnel construction method of engineering, railway and subway, high-speed rail shuttle Peak, tunnel waterproofing construction process using pre-shop. The waterproof construction method is in the initial part of the grassroots lining tunnel waterproofing concrete waterproofing membrane pre-shop, each laying a layer or some waterproof membrane, can be mechanically fixed, manual method, the waterproofing membrane is fixed at the grassroots level work surface enable effective waterproofing membrane lining structure fixed to the first tunnel waterproofing edges. When the waterproofing membrane laid fixed step is completed, the primary surface waterproofing membrane and then pouring concrete secondary lining, self-adhesive polymer film with cast concrete chemical cross-linking reaction, the waterproof layer and the structural layer to form a strong bonding, so as to achieve a waterproof, waterproof effect. 2. Metro underground construction methods and basement waterproofing industrial and civil buildings using pre-construction process spread anti-stick. The specific method of waterproofing is conducted before the construction of the main structure, which is the pre-waterproofing membrane laid on the cushion has been tidied plane or on the basis of inside the envelope. Waterproofing membrane or fixed after the laying of steps in the peripheral area of ??the inside of the waterproof membrane or envelope waterproof layer can then pouring concrete, polymer self-adhesive film with cast concrete chemical crosslinking reaction is waterproof layer structural layer to form a strong bond, so as to achieve a waterproof, waterproof effect. 5. Technical Specifications execution GB / T23457-2009? "Pre-shop, wet-laid waterproofing membrane" in the pre-shop P class VI Notes a coil into the site before construction ban in the sun exposure, in order to avoid high temperatures resulting in the isolation membrane tear Open difficult. Two wet-laid process during construction, due to high temperature in isolation is difficult to tear film can pour a little cold water in isolation membrane surface, reducing its temperature after isolation can tear film 3 sticky combination of good performance and therefore the product, once formed after the connection more difficult to recover, so they need to do in advance of construction project planning staff, the best time to be a one-time success Stones roll to avoid the inconvenience of repeated construction.
