Detailed introduction to waterproof membrane:
DY-APP Modified Bitumen Waterproof Membrane
Ilustration
DY-APP uses polyester felt or fiberglass felt as the original source, and APP, APAO, as the modifier, and covers the insulation materials as polyethylene, sands, or gravels.
Scope of Application
1, Basement and roofing of key waterproof engineering, general and civil engineering
2, Bridge, road, granary, tunnel, park, swimming pool, sewage purifying pool and others.
3, Especially adapting to the area with strong sunshine or high temperature.
Advantages
Good ability of anti-aging, anti-alkali, resistant to high temperature. High tensile strength and elongation, which adapts to the contraction or crack of the base
Construction Requirement Basement Treatment
1, Dry, strong, smooth and clean base.
2, Installation: Heating to melt, place the membrane correctly, fire torch, evenly heat the membrane and foundation, when the surface of the membrane is black and bright with a fusion layer, apply the membrane and press it into a solid and flat state .Bore the membrane is cool, seal the edge of joint by float.
Storage and Transportation
1, Different items, models, dimensions and grades should be stored separately.
2, Put the product in a dry ventilated place with the temperature lower than 50'c and the height less than 2 layers.
3, It will not be factorys if any problems caused by wrong transportation or storage or the storage years are more than a year.
4. All the rolls should be erect without any putting across or incline. Cover the canvas when necessary.
Cautions
1, Installation is forbidden in rainy days or temperature lower than 0'c
2, All the workers should put on special uniforms to keep safe when installing. There should be equipments for fire controls.
Area per roll: 15m2(2mm),10 m2(3mm),8 m2(4mm)
