Product Description
SBS modified asphalt waterproof rool is in accordance with national building materials industry standard GB18242-2000 for production, it uses SBS modified asphalt, such as thermoplastic rubber material for the coating to polyester tire, glass-embryo, compound embryo for embryo-based composite to fine sand, schist, aluminum, PE film material for the cladding. After the high-precision processing by hot-melt elastic waterproofing membrane. Flexibility of the low-temperature below 18 degree, heat degrees in more than 90 degree, and its elongation is good, and the water resistance properties is strong, the useful life of more than 15 years.
It has a good waterproof performance and aging-resistant capacity. It does not drip in high temperature, nor does break in low temperature. It is easy to use in construction, with no pollution to environmentbut a long service life.
It is widely used in waterproof and damp-proof works of roofs, basements, bathrooms and pools of industrial and civil architectures, waterproof, damp-proof, airproof, leakage-proof works of bridges, parking lots, swimming pools, tunnels and reservoirs and maintenance works of asphalt roofs. SBS modified asphaltwaterproof coiled materialsis particularly suitable for buildings in cold regions where structure frequently changes, whereas APP modified asphaltwaterproof coiled materials is particularly suitable to buildings in hightemperature regions where there is strong solar radiation.
Construction requirements requirements toward base layer: Base layer must be leveled, clean and dry. Water content shall be less than 9%. Adhesive bitumen primer is smeared evenlyon the surfaceof base layer firstly. Start the construction when it is dry.
Keep the sequence from high to low, far to near at the same height; Start the spreading work from lower place when at the same level. Spreading direction: When gradient slope is smaller than 3%, spread in the direction parallel with ridge; When gradient slope is 3% to15%, spread in the direction parallel with or vertical to ridge; When gradient slope is bigger than 15%, spread in the direction vertical to ridge.
Spreading method: Melting method: Heat the lower surface of coiled material and base layer with flame gun or other heating tools until asphalt on surfaces begins to melt and becomes bright black; Spread coiled materialswhile heating, and compact firmly with the pressing roller. Remember to adjust flame and speed; Keep the temperature of asphalt between 200 to 250 When the construction finished, use cold adhesive to seal lapping parts.
Cold adhesive method: Smear high polymer modified asphalt adhesive or other cold adhesive evenly on the surface of base layer with the squeegee; Attention to its thickness. Use rubber roller to spread coiled materials and remove air under then until compacted. When environmental temperature is lower than 15, melting method shall be employed to handle the lapping parts and ends of coiled materials.
Treatment of lapping parts: If lapped along longer lines, for single waterproof layer, thelappinglongitudinal/transverse width should not be less than 100mm; For double waterproof layers, it should not be less than 80mm. If lapped along shorter lines, for single waterproof layer, it shall not be less than 150mm; For double waterproof layer, it should not be less than 100mm. Besides, the work shall be done completely and evenly; All parts are melted or smeared; There must be some extra melted asphalt or code adhesive squeezed out to shape a strip.
Inspection and acceptance: When the construction is finished, to guarantee the long service life ofcoiled materials, please check over and make sure waterproof surface no bubbles, winkles, droppings nor peeling off. It shall be smooth and beautiful
