Waterproof membrane for roof :
The products are made by soaking the base in bitumen, or thermoplastic elastomer(Such as styrene butadiene-SBS),or thermoplastics(Such as atactic polypropylene-APP,APAO,APAL)modified bitumen, then covering double faces with elastomer(SBS)or thermoplastics(APP,APAO,APAL)modified bitumen, and last finishing the upward face with fine sands, mineral flakes(or Grains) or polythene membrane etc. while downward face with fine sands or polythene membrane.
It has good waterproofing and ageing-resistance function, not flowing at highest temperature and no crack at lowest temperature;
Easy application , no pollution, and long service life etc.
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, reservoir etc.
SBS modified bitumen waterproof membrane is specially suitable to the building waterproofing in cold area and to the buildings of changeable constructions while APP specially suitable to areas of high temperature and of strong sunshine.
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.
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
