SBS/APP bitumen wateproofing membrane - WB-001

APP/SBS Waterproofing Bituminous Sheet

FEATURES

1.Good waterproofing and ageing-resistance function,not flowing at highest temperature and no crack at lowest temperature.

2.Easy application,no pollution,and long service life etc.

3.Possess good tensile strength,elongation rate and size stability which could be well suited yje substrate distortion crack.

4.Good performance in anti-puncture,anti-broker,anti-resistance,anti-erosion,anti-mildew,anti-weathering.

5.Construction Is convenient,the melt method can operate in four season,joints are reliable.

USAGE

1.It is widely used for industry and civil building---the waterproof and dampproof of the roofs,basements,

toilets etc;and the waterproofing of bridges,parking area,tunnels,reserviors etc.

2.SBS modified membrane is specially being applied in the cold area with low temperature,while APP modified membrane is applied in the hot area with high temperature.

APPLICATION METHOD

1.Make sure the roof deck smooth ,clean and dry(Moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint till dry to start application.

2.There are two methods in application:

One way is by heating and melting method---Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted (not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.

The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install it to be fully sticked to roof deck.

By heating and melting method and by cold adhesive can be used in alternation in application as requested.

3.After application ,a full serious inspection is required to make sure no air bubble ,no fold,no falling away etc to guarantee the waterproof life.
