Product Overview :

●The Department of bituminous products or thermoplastic elastomer (such as styrene-butadiene block copolymer SBS), plastics (such as polypropylene random APP or crystalline a-low molecular weight polyolefin polymer APAO) modified asphalt tire-soaking, two Tu elastomer or plastic body Tu asphalt cover, spreading to the upper surface of fine sand, mineral tablets (films) information or polyethylene coating coverage, under the surface with fine sand or withdraw coverage by polyethylene membrane made of waterproof membrane.
●The product has good waterproofing and anti-aging properties and is not flowing high temperature, low temperature, not rattle, Construction simple clean, long life characteristics, Its main widely used in industrial and civil buildings basement roof of the pool bathroom waterproof and bridges, car parks, swimming pools, tunnels, ponds and other buildings waterproof, separated vapor permeability and asphalt roofing category of maintenance. SBS modified bitumen membrane especially in cold areas, and structural deformation of buildings prone areas waterproof, and APP modified bitumen material is applicable to high temperature, a strong solar radiation areas are waterproof.

●Its main widely used in industrial and civil buildings roof, basement, bathroom, etc. waterproof and bridges, car parks, swimming pools, tunnels, water storage tanks buildings waterproof, especially in cold areas, structural deformation frequency and high temperature, a strong solar radiation areas are waterproof.

Construction features :
（一）Primary requirements :
　The grassroots must be formed, cleaning, drying, moisture content should be less than 9%, then a weak cold oil grassroots uniform coating surface, wait for drying before the construction.
（二）Stones roll sequence direction
　　First order of the high-to low; The same height since the first term; The same plane from the low begins to Know. Know the direction of slope face "3% when the roof parallel to the direction of the Stones; 3%-15% the slope between the parallel or perpendicular to the direction of the roof brick; slope "when 15% of the roof perpendicular to the direction of brick.
（三）BRIEF :
1 Melting : Lance flame heating or other tool at the bottom sheet and grassroots uniform heating, began to surface melting asphalt and bright black state, Pin Pin brick baking sheet, using roller compaction pressure. We should also be careful in regulating the size and speed of flame, asphalt temperature is between 200-250 degrees Celsius. Construction has been completed, should use cold viscosity lap right side sealed.
2Cold bonding method : Using a rubber scraper will adhesive polymer modified asphalt or cold Mary cold tackifier resin and other passers-by brush uniform surface at the grass-roots level, and control the thickness, frontier shops roll edge with rubber roller extended file material to exclude air to compaction. When the temperature is below 15 degrees Celsius, the melt method should be adopted to deal with lap parts and the first part of membrane admission.
（四）Lap addressed :
At the long edge lap waterproof single lap horizontal width should be more than 100mm, double waterproof should ≥ 80mm; Short Side single lap time should be more than 150mm, 100mm ≥ should double. Meanwhile, homogeneous paste should not leak or melt leakage James, should have a small surplus thermographic asphalt or cold viscosity, extrusion and formed strip.
（五）Inspection and acceptance :
Construction after a thorough check to ensure that no bubbling waterproof surface, wrinkles, and the shedding of the shell with the phenomenon, so formation, beautiful, thus ensuring that the waterproof membrane life.
