Product Description
DY-BAC Self-adhesive Waterproof Membrane
It is a kind of reinforced self-adhesive waterproof membrane, made in polyester reinforcement and soaked by self-adhering polymer modified bitumen. The soaked felt is covered with polyethylene reinforcement , aluminum foil or sands and isolation paper on top of them . With the polyester felt , the tensile strength of DYS has been increased to resist the leak caused by the stress deformation and crevice from reinforced concrete, so it shall be the first choice to use RSRB as the waterproofing materials .
Product features
1. High tensile strength and elongation which adapts to contraction or crack of the base .
2. Excellent adhesive property and able to be applied in dampening surface, and good ability to resist the water break though.
3.Good acid, alkali and other chemical substances resistance.
4. High self-cure ability and extensibility
5. Easy operation and increasing working-efficiency to save expenses.
6. Nontoxic, flavourless , meeting the environmental requirements.
Technical Capacity Index
1.Ref to Executive Standard C840-1999 without any felts.
2.Ref to Executive Standard JC898-2002 with polyester felt.
Scope of application
I can be widely used in waterproof works on industry or civil s roofing, basement, tunnel ,the metal roofing , roofing greening and other waterproof projects.
Installation
1.Process : Base treatment ->Smearing the basic surface disposing pharmaceutical->Connection point treatment -> Laying the DYS -> Treatment at the end part -> Acceptance of project
2.Main points:
Base treatment: The base must be clean, solid, level, dry; no light, grit, rift and loosing dust. For a large recess , fill it with cement mortar and then level it . Remove the protrusion and clean dust.
Smearing the basic surface disposing pharmaceutical: Beat up the pharmaceutical fully , paint the base evenly .Reference volume 0.2kg/m2. Lay the sheets after it become dry .
Connection point treatment: All tube roots, such as tube for rainwater or through the walls , must be sealed before lay the sheets. The width between additional layers and vertical plane must be greater than or equal to 250mm.
Laying the DYS: Confirm the direction and order of the membrane, mark the base with the line, then stick the membrane. Spread out the rolled materials (the side layer of insulation should be downward), arrange them at the appropriate site, cut out by the requirement of the size , roll a sheet from one end to the mid part ,cut off the film if insulation and roll to compact with a roller .Repeat the above step for the other part.. When cracks or bubbles come to the membrane, it needs the sheets over than 100mm width to seal the false place.
Treatment at the end part: When the end part is on the horizontal or the vertical place, polyurethane sealant must be used on them. When the end part is on the façade place, metal strips , sealants and screws must be added to fix the end part.
Cautions
1. No steel or hard thing to pierce the membranes
2. In process of laying ,eliminate the air under the membrane and roll it to adhere to the base surface .
3.Keep the membrane from the dirty , polluted or frozen place or places with water.
Storage and Transportation
1. Different items, models dimension and grades should be stored separately.
2 .Put the product in a dry, ventilated place with the height less than 5 layers .
3. Guarantee period is a year in normal environment.
4. All the rolls should be erect without any putting across or incline. Cover the canvas when necessary.
