SBS elastomer modified asphalt waterproof membrane is based on SBS (styrene-butadiene-styrene) thermoplastic elastomer modified asphalt as the dip coating material, high-quality polyester felt, glass fiber felt, glass fiber reinforced polyester felt as the tire base, fine sand, mineral pellets, PE film, aluminum film, etc. As the covering material, the elastomer modified asphalt waterproof membrane made of special mechanical stirring and grinding.

APP plastomer modified asphalt waterproof membrane is based on APP (random polypropylene) or APAO, APO (polyolefin polymer) modified asphalt as the dip coating material, high-quality polyester felt, glass fiber felt, as the tire base, fine sand, mineral particle (sheet) material, PE film as the covering material, using advanced technology to refine the plastic body modified asphalt waterproof membrane.

Product features：

◎ Strong impermeable performance；

◎ High tensile strength, high elongation, good dimensional stability, strong adaptability to shrinkage, deformation and cracking of the base layer；

◎ Good high and low temperature resistance, SBS is suitable for building waterproofing in lower temperature environments, and APP is suitable for building waterproofing in higher temperature environments.；

◎ Good puncture resistance, puncture resistance, tear resistance, corrosion resistance, mildew resistance, and weather resistance；

◎ The construction is convenient, the hot melt method can be operated in all seasons, and the joints are reliable.

Construction process：

Melting method, cold adhesion method and hot and cold combination method

The coil can be constructed by hot melt method or cold bonding method alone, or it can be constructed by hot and cold bonding method, that is, cold bonding method for large areas, and hot melt method for lap joints.

Hot melt method: Use a flame spray gun or blowtorch to bake the bottom surface of the coil and the surface of the base layer, melt the asphalt on the surface of the coil, roll the coil forward while baking, and then roll it with a pressure roller to make it firmly bonded to the base layer or coil.

Cold bonding method: First evenly apply the adhesive to the waterproof base layer and the coil, and then paste the coil after a little cooling and drying. Then roll it with a pressure roller to squeeze out the air under the coil, so that the coil is flat, tightly and firmly pasted on the base layer or coil. Construction tools and accessories

◎ Construction tools for cleaning up the waterproof base layer: shovel, broom, dust blower, hand hammer, steel chisel, etc.

◎ Construction tools for coil paving: scissors, tape measure, elastic wire box, scraper, brush, pressure roller.

◎ Special hot melt equipment: single-head or multi-head hot melt spray gun or blowtorch.

◎ Accessories: base layer treatment agent, coil adhesive, closing pressure strip

Coil paving

◎ Before construction, the base layer that has passed the acceptance should be cleaned up and the dust at the edges and corners should be blown clean.

◎ The base treatment agent should be evenly and consistently applied, and do not apply it repeatedly.

◎ After the base layer treatment agent is dried, the roof waterproof project and the underground waterproof project need to be treated with additional layers according to the design requirements.

◎ Determine the order and direction of paving of the coil and stretch the line at the base layer, and then lay the coil. The pasting of different parts of the coil shall be constructed according to the following requirements.

◎ Roofing: the coil and the base layer are pasted at points or strips; the surrounding 800mm of the roof should be fully pasted; the area of the slope roof is more than 70%, and the coil and the coil are 100% fully pasted.；

◎ Basement floor: the coil and the base layer can be fully glued, dot-glued, strip-glued or empty, but the coil and the coil must be fully glued.；

◎ Basement vertical wall: both the coil and the base layer and the coil and the coil should be fully pasted；

◎ Additional layer: All general parts are pasted, and empty paving is allowed at the deformation joints.

◎ The order of paving is first high span, then low span; at the same height, first far and then near; on the same plane, paving starts from the low place.

◎ Roof paving direction：

◎ The slope <3% is parallel to the direction of the roof.

◎ The slope of 3%~15% is parallel to or perpendicular to the direction of the roof.

◎ When the slope is >15% or subject to vibration, it should be laid perpendicular to the direction of the roof.

◎ The lap joints parallel to the roof are in the direction of flowing water, and the joints should be laid in the direction of the dominant wind direction when perpendicular to the roof.
