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
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
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
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
Note: other specifications can be offered depended on agreements
between buyers and supplier.
Scope of application

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
