Elastomer modification asphalt Waterproof roll It is based on polyester felt or glass fiber felt, Thermoplastic elastomer - SBS （ benzene Ethylene butadiene styrene (EBS) rubber modified asphalt is the base material, and the surface is covered with polyethylene film, aluminum foil film, sand, colored sand, and shale film. High polymers such as SBS are completely dispersed into a reinforced network structure and refined by advanced technology, which endows the modified asphalt waterproof membrane with good performance.

Scope of application
Waterproof and anti-corrosion of roof, basement, cold storage, swimming pool, subway, tunnel, drinking pool, sewage pool and other structures of industrial and civil buildings. SBS waterproof coiled material is especially suitable for building waterproof in low temperature and cold areas and with large structural deformation.
Storage and transportation instructions
- During storage, transportation and transportation, coiled materials of different varieties, grades, specifications and grades shall be stacked separately.
- It should be stored in a cool and ventilated room to avoid rain, exposure to the sun, close to the fire source, and contamination or oil stains.
- During transportation, coiled materials must be placed vertically, and the height shall not exceed two layers.
SBS/APPA construction process
Base treatment
- The base course must be flat, free of looseness, peeling and sanding, and the roof water content shall be less than 9% before construction;
- The internal and external corners as well as the pipe root shall be made into arc shape, with the internal corner radius greater than 25mm and the external corner radius greater than 5mm;
- The base course must be leveled first, and the leakage must be plugged first.
Hot melt method and cold sticking construction
- Hot melt method: during construction, place the coiled material in the right position, bake the bottom surface of the coiled material and the surface of the base layer with a flame gun or a torch (the torch is preferably 0.3mm away from the coiled material), heat evenly, melt the surface of the coiled material, roll forward evenly, and then roll with a pressure roller, which must be compacted and flattened to make it firmly bonded with the base layer or coiled material. Note: High polymer SBS solvent waterproof coating shall be applied to the surface lap edges and special complex parts, and then applied again.
- Cold bonding method: first, evenly brush the adhesive on the waterproof base course and the coiled material. When paving the coiled material, leave 10cm longitudinal and 20cm transverse joints of the lap edge. After drying slightly (about 20min), paste the coiled material. Then roll hard to squeeze out the air under the coiled material, so that the coiled material can be smoothly, tightly and firmly pasted on the base course or coiled material.
Coiled material paving
- The base course treatment agent shall be painted evenly and uniformly, and shall not be painted repeatedly. After the treatment agent is dry, the additional layer shall be laid at the position where the additional layer is required.
- Determine the coiled material sequence and paving direction, snap the line on the base layer, and then pave the coiled material. The pasting of different parts of the coiled material shall be carried out according to the following requirements.
- Roof: point or strip pasting of coiled material and base course; 800mm around the roof shall be fully pasted; The bonding area of the slope is more than 70%, and the coiled material is fully pasted with high standards;
- Basement floor: coiled material and base layer can be fully bonded, point bonded, strip bonded or empty paved, but coiled material and coiled material must be fully bonded;
- Basement vertical wall: coiled material and base layer, coiled material and coiled material must be fully pasted;
- Additional layer: general parts are fully pasted, and empty paving is allowed at deformation joints.
Coiled material paving
- Long side overlapping: the longitudinal overlapping width of coiled material is ≥ 80mm, which must be carefully operated, and the adhesive shall be applied evenly without omission. The edge of cold bonded coiled material shall be extruded with excess adhesive. The hot melt method shall form an asphalt strip at the edge.
- Short edge lap: both ends of coiled material must be bonded. The overlapping width shall be ≥ 100mm. When the polyester tire coiled material is used for spot bonding, the two ends must be fully bonded for more than 500mm; Cold bonding method: adhesive shall be extruded at joints. Hot melt method: asphalt strips shall be extruded at the joints.
- When paving two adjacent coiled materials on the same layer, the transverse overlapping edges shall be staggered by more than 1500 mm, and the upper and lower layers of coiled materials shall not be paved vertically.
- The shale layer shall be removed when the short edge of coiled material with shale flakes is lapped. The method is to scrape off the shale part with a trowel after heating with flame. Butt joint can also be used. The method is to pad 300 mm coiled material strip under the joint. The coiled material is horizontally butted, and the joint is treated with sealing material.
- After the coiled material is paved, the lap joint, end and coiled material end must be sealed. Sealing material, sealant or cold adhesive shall be filled and then trowelled to form obvious asphalt strip.
