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.

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 is the resistance type SBS waterproofing membrane?
There are three main principles of root-resistant puncture waterproofing membrane: The first is a physical resistance to the beam with the piercing strength as a resistance method.
Q:How is the water level rated and how many grades are used?
1, roof waterproof level 1: Application: particularly important or waterproof with special requirements of the building; Waterproof layer of reasonable use of life: 25 years; Waterproof layer selection of materials: should use synthetic polymer waterproofing membrane, polymer modified asphalt waterproofing membrane, metal sheet, synthetic polymer waterproof coating, fine stone concrete and other materials; Fortification requirements: three or more than three waterproof fortification.
Q:What is waterproofing membrane?
Waterproof membrane requirements have good water resistance, stability of the temperature change (high temperature does not flow, no blistering, not confuse; low temperature does not brittle crack), a certain mechanical strength, extensibility and resistance to fracture, to There is a certain degree of flexibility and anti-aging and so on. The waterproofing membrane is a curlable sheet-like waterproofing material. Is one of the important varieties of waterproofing materials in construction engineering.
Q:It is good for black roof with waterproof paper
No film or PE film (black surface) coil is generally not used for the roof; if the roof is often on the need to lay in the coil above the 5 cm thick cement mortar to do the protective layer or the choice of sand and shale surface waterproof Coil. Lough membrane (silver surface) The role of the membrane to play the radiation can be used directly for the roof without any protection.
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
1, foundation pit membrane waterproof is the entire basement part of the package. So the basic floor of the waterproof material and the external walls of the waterproof material as much as possible.
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:What is the use of waterproof membrane?
Therefore, the role of waterproofing membrane in waterproof construction can not be ignored.
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:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC refers to butyl acetate, BAC waterproofing membrane is a composite double-sided self-adhesive rubber asphalt waterproofing membrane, the coil material in the polymer (chain) and cement hydrate (silicate network) (Interfacial) interpenetrating network (IPN) structure, cement can be flow, infiltration or impregnation, solidification strength increases, the cohesive force increased. The leakage caused by the damage caused by the coil can be limited to the local scope, to avoid leading to the overall failure of the waterproof layer. BAC composite self-adhesive waterproofing membrane elongation performance, with a unique self-healing function, can self-healing smaller puncture damage, can automatically fill the smaller grass-roots cracks.
