Product Description:

itis a modified bitumen
 base sheet consisting of polymer modified asphalt added viscosifier inside covering with different upper separated materials and underside with silicone antisticking layer. According to different upper surface, it includes three types: PE film surfacing (SAM-930APE), sand surfacing (SAM-930AS) and antisticking surfacing (SAM-930AN). There have two kinds of thickness: 3.0 mm and 4.0 mm.

Surface Preparation
Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and uneven places need to be filled by polymer mortar.
Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
Membrane laying
After substrate treating agent drying, lay SAM-930A material according to application designs.
Sealing, fixing and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.

Q:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
Do not indicate the thickness can contact the design unit, you can also judge according to the waterproof level
Q:The difference between waterproof linoleum and waterproofing membrane
`Linoleum is a kind of waterproofing membrane! Belong to subordinate relationship. Felt is made of animal hair or plant fiber made of carpets or thick paper impregnated asphalt after the building materials, toughness, impermeable, used to do the roof, basement walls, foundations such as waterproof, moisture-proof layer. Also called oil felt. Approximately 2000 years ago, the most commonly used building waterproof material, has now been included in the scope of national banned building materials. At present, the construction of waterproofing membrane is large "elastomer modified asphalt waterproofing membrane" - the implementation of standards for the GB 18242-2008.
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
Polyethylene polypropylene waterproofing membrane from the middle of the "polyethylene" chip, two-sided composite "polypropylene non-woven" made, one method is in the extrusion production of polyethylene film at the same time, when the polyethylene is still in a soft state , In the upper and lower sides of the membrane composite polypropylene non-woven, the temperature can not be too high and polypropylene buried too much, the temperature can not be too low, otherwise the sticky on the sticky.
Q:Sbs waterproofing membrane can make bathroom waterproof?
And can be used in the basement, bridges, parking lots, swimming pools, tunnels and other buildings waterproof, moisture, steam, impermeable and various types of roof maintenance works, and the service life is very long, basically not bad,
Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level
SBS modified asphalt waterproofing membrane, this coil has a good high temperature performance, can be -25 to +100 ℃ temperature range of use, a higher flexibility and fatigue resistance, and up to 1500% Elongation and strong puncture resistance, tear resistance. Suitable for cold areas, as well as deformation and vibration of large industrial and civil buildings waterproofing works.
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
 For the vibration of the roof, such as the use of parallel roof ridge direction asphalt waterproofing membrane, under the influence of vibration, easy to slip the membrane waterproof layer. And therefore should be vertical roof ridge direction. But the high strength of synthetic polymer film can not be limited.
Q:What is called a waterproof roll dry shop, wet shop
Dry shop, wet shop is said self-adhesive coil. Dry shop is in the formation of the grass on the first layer of primary treatment agent, and then paving self-adhesive coil method is the easiest and fastest way.
Q:Waterproof membrane in the escape when the full shop, empty shop, shop, shop what is the difference?
Coil construction process: 1, full of paving the film, the membrane and the base layer with all sticky.
Q:What is BSB waterproofing membrane
 Features: The coil has excellent high temperature resistance and can be used at -25 in the temperature range of + 100 ° C, with high elasticity and fatigue resistance, as well as up to 1500% elongation and strong puncture resistance , Tear-resistant cold. Suitable for cold areas, as well as deformation and vibration of large industrial and civil buildings waterproofing works. Low temperature flexibility is good, to -25 ℃ does not crack; high heat resistance 100 ℃ does not flow. Good extension performance, long service life, simple construction, small pollution and so on.
Q:What is the preferred level of waterproofing?
2, roof 2 waterproof: Applications: important buildings and high-rise buildings; Waterproof layer of reasonable use of life: 15 years; Waterproof layer selection of materials: should choose high polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal sheet, synthetic polymer waterproof coating, high polymer modified asphalt waterproof coating, fine stone concrete, flat tile, linoleum Tile and other materials; Fortification requirements: two waterproof fortification.
