Fire Torch Applied 4mm Membrane Sheet Polyester Reinforced For Concrete Roof

Asphalt Roofing Membrane For Building Waterproof Function

SBS Asphalt roofing membrane Introduction:

SBS (styrene-Butadiene-Styrene) rubber polymer , is a waterproofing membrane manufactured from modified bitumen with the additional elastomers SBS rubber, which is flexible and has the memory to return to its original form. The addition of SBS rubber to asphalt increase the flow characteristics and improves the low temperature flexibility and fatigue resistance of roofing asphalt.

SBS Asphalt roofing membrane application fields:

It is used in curtain walls, foundations, and projects with high tensile requirements, basement walls, balconies, terrace roofs, inclined roofs, water tanks, manmade ponds, retaining walls, concrete channels as well as bathrooms and any wet surfaces.

SBS Asphalt roofing membrane features:

1.Good combination of rigidity and flexibility. The properties of cement slurry greatly improve the adhesion of the waterproof layer. It is still  inseparable under long-term soaking. 

2.Easy to repair.

3.The occurrence of water channeling can be avoid because the membrane is firmly bonded with the cement slurry.

4.Even when the membrane is partially damaged, water can be limited to a small range.

SBS Asphalt roofing membrane data:

Application:

10 cm overtopping shall be allowed for joints and 15 cm overtopping for ends by using welding torch. The surface coated with mineral stone on joints should be heated and minerals should be buried in to the bituminous surface by using trowel before welding the joints together. The transverse joints of the first layer covering should be laid down in an offset position. For the top layer, longitudinal and transverse joints of the first layer should be centered. Roof covers should be laid perpendicular to the slope from the point where the slope is lowest.
