Gb-18284 Modified Bitumen 3mm Sbs Waterproofing Membrane Polyester Reinforced

Introduction:

SBS (Styrene-Butadiene-Styrene) modifies the asphalt by forming a polymer network within the bitumen. SBS gives the bitumen rubber-like characteristics and improved resistance to aging and weathering. Most SBS modified bitumen sheets are either set in hot mopping asphalt, torch-applied, or adhered with cold-process adhesives. SBS modified bitumen sheets that do not have factory applied granule or foil surfacing need some form of field-applied ultraviolet protective coating.

Benefits:

) SBS/APP modified bitumen waterproof membrane

2) conforms to the national standards

3) embossed belt and PE waterproof membrane

4) popular in Australia, Korea and the USA

5) technique:spunbond

6) length of roll:10m

7) core material:polyester mat or composite mat

Applying method:

Basic requirements: The substratum should be smooth, clean, dry (Moisture<9%), then apply the surface of stratum evenly with bitumen oil, and application is allowed till dry.

Heating and melting method: Place the membrane correctly, fire torch, evenly heat the membrane and foundation Before the sheet is cool, seal the edge of joints by float. Use flame gun or other tool to heat evenly in the bottom layer of membrane ,when the surface of the membrane is black and bright with a fusion layer apply the sheet and press it into a solid and flat state.

Checking and acceptance: a thorough inspection is required after application to insure there is no air bubble, no falling away and etc. to guarantee the waterproof life.
