PET Wet-application Waterproofing Membrane

Generally speaking, there are three factors lead to Seepages:
1. Waterproofing layer is imperfect: It’s hard to completely avoid weak points or breakages, which makes waterproofing layer with deficiencies or hidden defects more or less.
2. The main structure is with defects: It’s hard to completely avoid construction joint, deformation joint and small fissures in structure.
3. If there are weak points or breakage, water gets in and fluid-channeling happens between the main structure and the waterproofing layer. In such cases, once the main structure is with defects, seepages would occur.
In most cases, traditional waterproofing materials can only form into a "protective film" in ideal status, thus, commonly seen thorny problem would arise. Any defect in waterproofing layer can lead to fluid-channeling, which could further make larger area of waterproof layer even the whole lose efficacy. Obviously, in terms of waterproofing system, tackling the problem of fluid-channeling is the most convenient and effective way to solve leakage problems.
PET waterproofing membrane system is the one of the most effective way in solving the problem above. By adopting wet-placement application, it sticks to the base closely and firmly, forming a reliable “Skin Type” waterproofing system which can eradicate fluid-channeling phenomenon thus root out necessary conditions for seepage. In such cases, even if there are defects between the main structure and the waterproofing layers, seepage would not happen generally.
PETTMWet-application Waterproofing and “Skin Type” Waterproofing Theory
PET wet-application waterproofing membrane is made of self-adhesive rubber bitumen as master material with highest water impermeability and cement as the cheapest adhesives, constituting the most reliable and economical waterproofing system called "Skin Type”.
On side walls, head plates and roofs of basements, with wet application of cement slurry or cement mortar, they are combined tightly into one unit with the structure, enhancing the reliability of waterproofing layer without worries about fluid-channeling.Advantages:
1.Ultra-strong adhesion property can stick to the substrates tightly which beyond your image.
2.Saving construction materials but achieve a perfect waterproofing effect. High standards waterproofing projects adopt multilayer application, so that reveal its excellent waterproofing feature.
3.Safe and environment-friendly. Wet-application with cement-based materials, no need to prime coat and hot melting, no volatile solvent, no hidden fire hazards and no harm to human bodies.
4.Strong damage resistance and simple for repairing once incurs to breakage.
5.Covered and protected by cement-based adhesive materials, possessing rigid waterproofing function so that creates one waterproofing layer but diploid prevention.
6.Easy to find out and repair the breakage spots, low maintain cost, and no phenomenon of fluid-channeling, all above promote its water self-locking property.
7. Construction application seems like blockhead and convenient to handle.

Scope of application
Waterproofing, anti-seepage and moisture proof of basements and roofs.
Standards GB/T23457-2009
Storage and Transportation:
1. Different types or specifications of products should be separated, not mixed.
2. Keep it dry and ventilated, protected from the sun or rain.
3.Storage temperature should never be higher than 45 ℃. Pile up the membranes flatwise whose stockpile height never exceeds five layers. One layer is guaranteed if it is placed vertically.
4. Prevent it from inclination or lateral pressure. If necessary, cover it with felt-cloth. 5. Storage time is at least one year from manufacture date on if the product is under normal operation of storage.
