Product Description:

 Description Of EPDM  Waterproof Membrane:

1. Waterproofing layer is imperfect: It’s hard to completely avoid weak points or breakages, which makes waterproofing layer with deficiencies or hidden defects more or less.

2. The main structure is with defects: It’s hard to completely avoid construction joint, deformation joint and small fissures in structure.

3. If there are weak points or breakage, water gets in and fluid-channeling happens between the main structure and the waterproofing layer. In such cases, once the main structure is with defects, seepages would occur.

Main Features of EPDM  Waterproof Membrane:

  1. Different types or specifications of products should be separated, not mixed.

  2. Keep it dry and ventilated, protected from the sun or rain.

  3. Storage temperature should never be higher than 45 °C. Pile up the membranes flatwise whose stockpile height never exceeds five layers. One layer is guaranteed if it is placed vertically.

  4. Prevent it from inclination or In the process of transportation, it should be lying in case of inclination or lateral pressure. If necessary, cover it with felt-cloth.

  5. Storage time is at least one year from manufacture date on if the product is under normal operation of storage.

Q:What is the difference between polymer waterproofing membrane and cross film waterproofing membrane?
he strong cross-over film of the product is a high-strength HDPE film formed by the cross-laminating process. The film and the like have the same vertical and transverse elongation ratio. The coil does not send deformation, more beautiful and waterproof reliable.
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:Is the waterproofing membrane an insulating material?
2, with a metal foil surface modified asphalt waterproofing membrane, in order to expose the use of extended durability period, the surface of the composite layer of metal foil.
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
The direction of the web should be determined according to whether the slope of the roof and the roof is affected by vibration: when the slope of the roof is within 3%, the asphalt waterproofing membrane should be parallel to the roof; at 3% ~ 15%, the asphalt waterproofing membrane may Parallel or vertical roof paving; slope greater than 15% or by vibration of the roof, asphalt waterproofing membrane should be vertical roof paving, and polymer modified asphalt waterproof and synthetic polymer waterproofing membrane can be parallel or vertical roof paving; The upper and lower layers should not be piled with each other vertically.
Q:About asphalt waterproofing membrane
2, SBS refers to the use of SBS rubber into the asphalt, the performance of the asphalt to improve the use of polyester felt or fiberglass as a tire base, the surface with polyethylene film or other materials for the isolation layer. The general thickness of 3mm 4mm.
Q:Waterproof building materials after the construction of drums, bubble is what reason?
Reason 3: synthetic polymer waterproofing membrane construction, if the adhesive is not fully dry on the eager to paving the membrane, resulting in a solvent residue in the coil inside, when it evaporates, it will form a bubble. Control measures: the use of cold and cold method of paving, the brushing of the adhesive to be uniform, to be dry when the handle (refers to touch) is not bonded, before paving the membrane, while compaction. In particular, to prevent the accumulation of adhesive too thick, dry operation caused by the film from the drum.
Q:What is the meaning of the node and the additional layer in the construction of the membrane waterproofing layer?
Waterproof membrane construction, the node is relative to the large area of the plane in terms of. Node parts are: yin and yang angle, the root of the pipeline, the rain shed, all kinds of flooding, expansion joints, deformation joints, construction joints, through the wall and other areas need to focus on processing.
Q:1.2 thick synthetic polymer waterproofing membrane two weight how to count
Polymer waterproofing membrane is generally 1100 ~ 1400kg / m3, 1.0mm thick per square meter weight of about 1.1 ~ 1.4kg / m2, 1.2mm thick coil weight of about 1.3 ~ 1.7kg / m2, plus lap 10% , 1.2mm waterproof layer of the weight of 1.45 ~ 1.85kg / m2, if the adhesive paste, plus adhesive weight 0.2 ~ 0.4kg / m2, the total weight of about 1.7 ~ 2.3kg / m2, two about 3.4 ~ 4.6 Kg / m2.
Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
The vulcanized waterproofing membrane is characterized in that it consists of a vulcanized butyl rubber, a softening agent, a hard acid and a filler, wherein the parts by weight are butyl rubber: softening agent: hard acid: filler = 1 : 0.003-0.015: 0.006-0.036: 0.32-0.73, wherein the softening agent uses a mechanical oil, which can also be made into a high-strength waterproofing membrane by sandwiching a layer of the web between the two layers of the waterproofing membrane.
Q:What is the material on the insulation layer on the waterproofing membrane?
2, waterproof layer on the other construction layer construction, it is possible to pierce the waterproof layer, the appropriate protection Is necessary, the isolation layer can also play a protective role.
