Hot Melt SBS APP Bituminous Membrane

1.introduce

Hot  Melt SBS Bituminous Waterproofing Membrane is made by soaking the base in  bitumen or Thermopylae ticityelastomer(such as styrene butadiene-SBS) modified  bitumen, then covering double faces with elastomer(SBS) modified bitumen, and  lastfinishing the upward face with fine sands, mineral slates(or grains) or  polythene membrane etc, while downward face with fine sands or polythene  membrane.

Mostly important waterproof projects and civil  construction projects for  slope roof,  wallcoating, underground waterproof , bathroom membrane, washroom membranes etc  , waterproof and moisture proof .
 Bridge , road ,park,swimming pool , tunnel, water  reservoir,water tank  waterproof  membrane.
 

5.Applications Method:
 1) Base processing: the base surface must be  clean, solid, level, dry; no grit, rift and loosing dust. For a large recess,  fill it with cement mortar and then level it. Remove the protrusion and clean  dust. If working on base slab or lateral face, water lowering should be done.
 2) Painting primer: before laying the membrane,  clean the dust on the surface of concrete base with dust catcher or  dust-blower.
 3) Heat to melt: place membrane correctly, fire  torch, heat the membrane with base entirely, when the surface of the membrane  is black and bright with a fusion layer, apply the membrane and press it into a  solid and flat state. Before the membrane is cool, seal the edge of joint by  float.
 4) Requirements for lapping: There should be less  than 3 layers of lapping, with the joint seams appearing as "T" type,  avoid 4 layers of lapping. The width of longitudinal lapping is between 50 and  80mm, and of end-lap joint 100mm.

7,  Precautions:
 1).  Basement complex conditions, good income header processing quite critical, so  be careful construction, lap seal (or seam) in order to ensure the integrity of  the waterproof layer, waterproof membrane lap joint is weak layerLink, it must  do edge treatment.
 2). The  operator may not wear nail shoes, flat shoes should wear soft construction.
 3).  Winter construction should choose low temperature of the web 10 ℃ lower than  the temperature of the product, and the web store above 0 ℃ areas, before moving  into the field use, handling to prevent break.
 Hot  melt construction, brushing primary treatment agent must be dried for 4 hours  (or more appropriate sticky feet) above Stones roll operation can be carried  out, in order to avoid fire, the construction site should be configured with  the right amount of fire-fighting equipment.
 

8,  Storage&Shipment
 1)  Different items, models, dimensions and grades should be stored separately.
 2.  Store the products in a dry and ventilated place with the storage temperature  less than 50℃, and products should be placed upright and stacked no more than  two layers.
 3) Keep  products in an upright position during transportation., avoid incline and cross  squeeze between rolls.
 4) The  shelf-life is one year under normal storage condition.
