Polyester Reinforced Self-adhesive Bituminous Roll Material is a special self-adhesive and creeping compound who is composed of Stylene-Butadiene-Stylene (SBS) thermoplastic elastic modified bitumen and cementitious material as dipping and coating material.synthetic polymer (HDPE.HEVA. PVC) as reinforcement.and polyethylene (PE) film as insulation. By adopting wet- applied/pre-applied.DCPS membrane can supply a gapless complete waterproof sealing system.it will construct a strong bonding between waterproofing membrane.polymer cement and basement.so realized full and permanent combination.forming a reliable “Skin Type” waterproofing system.
3.1 Good performance of tensile strength.elongation.creeping and self-healing.
So it is very adaptive to base deformation shrinkage.and cracks.
3.2 Low requirements for substrates and short construction period
No mater wet or non-level substrates are available to apply. No need to primer.high flexibility of application.being not influenced by temperature.more remarkable advantages while in rain days.all above become the most power weapon to shorten the construction period.
3.3 Easy to overlap and seal
The materials not only has adhesive itself which can reach self-adhesive overlap firmly.but also can tightly bond to coatings like SPU that be brushed on its surface. These features solve the difficulty in pipe lining.winding up and joint.achieving seamless process of membranes.
3.4 Adhesion Reliable & Convenient to Be Checked &Repaired
wet-application membrane can make a good and lasting bond to the structure. If there is local failure on the membrane.water would be confined in a limited area without fluid-channeling. Even there is seepage.the seepage point would be at the breakage point.which makes it easy to repair the leakage.
3.5 Safe and Environment-friendly
During construction.there is no solvent or fuel involved.avoiding pollution and fire risks and saving resources as well.
1)Various types of industrial and civil buildings.
2)Subway.tunnel.bridge and highway.
3)Garbage field.artificial lake.water conservancy project.hydropower and pipelines.

6,Constructions - Wet Application:
6.1.1 substrate treatment: remove dust.debris from the substrate surface.dry surface should be wetted out first.but no ponding left. These sharp corners should be treated by mortar first with min. 50 mm radius for internal and min. 20 mm radius for external corner.
6.1.2 Scrape a thin layer of cement (mortar) over the substrate surface.mortar layer shall be wider than membrane by 100~300mm.
6.1.3 All joints (corners.construction joints.post-cast strips.deformation joints and through-wall pipelines) should be reinforced first.
6.1.4 Peel off isolating film of the membrane lower surface.pave the membrane onto mortar layer along the alignment.and keep min. 60 mm overlap for joint area.
6.1.5 Press it down.exhaust any trapped air.and make sure membrane and mortar having a tight contact for the entire area.
6.1.6 Use a hand-hold press roller to roll and press the lapping area.exhaust air.and ensure a tight bonding.
6.1.7 acceptable check.
6.1.8 Advantages: the construction of the base surface can be damp.suitable to apply in rainy reasons
1 )Don’t install if the temperature is lower than 0 ℃.the basement is polluted.there are water or ice on basement.
2) Don’t install with others construction processes at the same time.if need to install others facilities on ready waterproof layer.take actions to protect the waterproof layer from damage and the waterproof layer under facilities should be reinforced.
3) Don’t put any material.machines or facilities on ready waterproof layer.and don’t touch the waterproof layer with any sharp objects in order to prevent the waterproof layer from damage.
Different items.models.dimensions and grades should be stored separately.
Store the products in a dry and ventilated place with the storage temperature less than 50℃.and products should be placed upright and stacked no more than two layers.
Keep products in an upright position during transportation..avoid incline and cross squeeze between rolls.
The shelf-life is one year under normal storage condition.not be more than one year.
