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.
 
Priming
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.


FAQ

Q:APP selection of asphalt waterproofing membrane selection points
1, I type polyester tire or glass fiber tire modified asphalt waterproofing membrane PET higher heat resistance, but low temperature flexibility is poor. Suitable for non-cold areas for general construction works of the roof waterproof layer. The waterproofing material of the upper surface material of polyethylene film or fine sand shall not be exposed.
Q:What should the attention of the membrane waterproof construction?
(4) Coil Lap Adhesive: After the web is compacted, the lap is opened and the lacquer is applied with the paint brush to apply the two adhesive surfaces of the coil joint. After a moment of dry feel when the sticky, you can glue, and then press the rubber hammer knocked dense, so as not to cause leakage of slit; (5) waterproof layer construction temperature selection above 5 ℃ is appropriate.
Q:What is rigid waterproof, flexible waterproof?
3, not all waterproof only sub-rigid waterproof and flexible waterproof, such as metal roofing. Basement concrete structure waterproofing is usually not called rigid waterproof.
Q:DTM.E polyester composite waterproofing membrane, cheaper than the asphalt membrane?
Ouwei Jianke DTM.E polyester composite waterproofing membrane is the company according to GB50207-2002 "roofing quality acceptance norms", GB50108-2008 "underground engineering waterproof technical specifications", GB50208-2002 "underground waterproofing project quality acceptance norms" and Other waterproof engineering design Widely used in a new type of waterproof material,
Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level
For the PE film (aluminum), color sand, shale, fine sand and other four categories; width: 1000mm, 10m long, 15m two specifications; thickness: polyester felt coil 3mm, 4mm, 5mm; fiberglass membrane 3mm, 4mm; glass fiber reinforced polyester felt 5mm Scope: Widely used in industrial and civil construction of the roof, basement, bathroom and other waterproofing works and roof gardens, roads, bridges, tunnels, parking lots, swimming pools and other projects waterproof and moisture. Deformation of the larger project recommended the use of excellent extension of the polyester tire products, other buildings should choose a relatively economical glass fiber products. So look at the temperature and then choose.
Q:What kind of waterproofing membrane, waterproofing membrane is how to classify their respective advantages?
Waterproof membrane classification are: EPDM waterproofing membrane, SBS asphalt membrane, PVC waterproofing membrane, TPO waterproofing membrane. Advantages and Disadvantages
Q:What is the PEDM waterproofing membrane material?
Process: clean up the grassroots → brushing the primary treatment agent → additional layer of treatment → film paste surface coating → base surface coating → coil bonding, exhaust, compaction → coil joint bonding, compaction → roll Material end of the head and edge processing → do protection.
Q:PVC waterproof membrane effect how
4, hot-melt method: the use of flame heater melting hot-melt waterproofing membrane at the bottom of the hot melt adhesive bonding method of construction.
Q:Can waterproof sheets be used on steel roof panels?
to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials , As the engineering foundation and the building between the no leakage connection, is the entire project waterproof first barrier, the whole project plays a vital role.
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
These two kinds of materials from the current surface is exactly the same, if it is experienced people, you can through the tension on the sheet asphalt to determine the initial situation, if the domestic refrigerator can reach -25 ℃ low temperature, can also be low temperature flexibility Not broken after the initial judgment). To correctly determine the need for sample inspection.
