The product is made of elastomer (SBS) or thermoplastic (ASP, APAO, etc.) modified asphalt impregnated fetal base, both coated with elastic or plastic modified bitumen coating, the top surface with fine sand, mineral particles ) Or a polyethylene film or the like.
 The product has a good waterproof performance and anti-aging properties, and has a high temperature does not flow low temperature not brittle crack, simple construction, long life useless features.
 Widely used in industrial and civil buildings of the roof, basement, bathroom and bridges, car parks, swimming pools, tunnels and other buildings waterproof, moisture, steam barrier, impervious and various types of roof maintenance works. SBS modified asphalt tile waterproofing membrane is especially used in cold, structural deformation of the building frequent areas of waterproof, and ASPP modified bitumen membrane is suitable for high temperature, strong solar radiation areas of the building waterproof.

Key points of construction

Basic requirements: grass-roots must be smooth, clean, dry, moisture content should be less than 9%, and then use the primer evenly paint the surface of the grassroots, dry until after the construction.
 Paving order of the direction of the coil: the order of the first high, after the low-span; the same height after the first near the same; the same plane from the lower start paving. When the slope is 3% ~ 15%, it is paved in the direction of parallel or vertical ridge: when the slope is more than 15%, it will be paved perpendicularly to the direction of the ridge.
Paving methods:
 Hot-melt method: Flame spray gun or other heating tools at the bottom of the coil and the base layer uniform heating, until the surface of the asphalt began to melt and was black and bright state, while baking side paving sheet, and compaction roller. At the same time should pay attention to adjust the flame size and speed, so that the asphalt temperature maintained at between 200 ~ 250 ℃. After construction, should be re-use cold adhesive on the tower side sealing treatment.
 Cold adhesive method: with a rubber scraper to high polymer modified asphalt adhesive evenly brushing the surface of the primary, and then roll the side edge of the roll with a rubber roll roll out the side of the air to the compaction roll. When the environment is stable below 15 ℃, the hot-melt method should be used to deal with the location of the tower and coil closing parts.
 Tandem treatment: the long side of the tower when the single-layer waterproof tower connection width ≥ 100mm, double-layer waterproof ≥ 80mm, short-side when the tower should be ≥ 150mm, double layer should be ≥ 100mm. At the same time, the paste should be uniform, not leaking melting or leakage coating, there should be extra hot-melt asphalt or cold adhesive extrusion and the formation of strip.
 Inspection and acceptance: After the completion of the construction to conduct a thorough inspection to ensure that the water surface without drum kits, wrinkles, off and a large shell from the phenomenon, so smooth, beautiful, so as to ensure membrane waterproof life.


1. Basement conditions are complex, good end of the deal is quite critical, it should be carefully construction, sealing lap (or seams) is to ensure the integrity of the waterproof layer, membrane lap joint is the weak link waterproof layer, so Edge processing must be done.
2. Operators shall not wear nail shoes, should wear soft flat shoes construction.
3. Winter construction should select the low temperature flexibility of the membrane temperature 10 ℃ lower than the product, and the coil stored at 0 ℃ above the place, before use, moved to the scene, handling to prevent break.
4. Hot-melt construction, brushing the grass-roots treatment agent must be dry for 4 hours (more than sticky feet is appropriate) above the roll paving operations in order to avoid a fire, the construction site should be equipped with appropriate fire fighting equipment.

Packaging, transportation and storage

1. The product is packed in paper or plastic tape.
2. Transport to prevent sun and rain, to prohibit access to fire, to prevent collision, protect the packaging intact.
3. Products should be stored in the warehouse sealed, stored in a cool shade, prohibit access to fire.
4. In the normal storage, transport conditions, the storage period from the date of production for 12 months.
