Product Description:



Introduction for EPDM Waterproofing Membrane:                                                                                 

Waterproof membrane for roof adopt the international advanced level cold feed extrusion continuous vulcanization process for the integration of production equipment and technology so that the system density of products is better and the products have no bubble sooth surface, no performance difference between vertical and horizontal.

 

Characteristic of EPDM Waterproofing Membrane:                                                  

· with adhesive tape on the overlap for the sealing of junction,convention for application.

· Excellent weather resistance, corrosion resistance, anti-aging, antioxidant. 

· Excellent waterproofing performance and encase nail holes.

· Good permeability, can be in damp base surface construction, make the maintenance structure internal water vapor rapidly eduction, avoid effectively mould and condensing formation
Excellent tensile strength and elongation.

· large Surface friction, grass-roots closely.
no smell,no taste,accord with environmental protection requirements.

Q:What are the requirements for frost resistance of basement floor polymer waterproofing membranes?
Requirements are, when the material quality testing, the ground temperature must meet the requirements of national norms.
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:What is the difference between pressure-sensitive self-adhesive waterproofing membrane and sbs asphalt waterproofing membrane?
1, from the product level (1) pressure-sensitive self-adhesive waterproof membrane is a new type of product, is the fourth generation of products, and Sbs asphalt waterproofing membrane is the second generation of products, so that the former is a new product, then the effect is certainly better than
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
 As for the upper and lower layers are not allowed between the vertical paving, the reason is that after the paving more heavy joints, and heavy seam is the most vulnerable to leakage of weak parts.         Dragon waterproof experts to remind you: things always have a dual nature. In the southern region, the temperature is high, rainy days, to the web paving brought a lot of difficulties. In order to waterproof roofing, when the rain is easy to coil joints, in addition to less than 3% of the roof slope, the remaining slope of the roof coil should take the vertical roof direction paving.
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
3, you say waterproof and pouring concrete conflict? Do not conflict
Q:The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
but the current domestic Still less match with the binder, because the environment and bonding materials and other factors often lose their bond function in advance, resulting in water failure will be self-evident; then waterproofing membrane after the construction of the protection And the leak after the maintenance is also a problem, exposed to the outside of the waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and grass-roots bonding, whether it is full shop, shop, shop, empty shop, The grassroots will be between the water layer, regardless of any part of the penetrating breakage, degumming, leakage of glue (even if there is only one), the entire level of its connection with the waterproof function will all decline, if not Find damaged and defective parts, the local repair is not possible, then only redo waterproof layer. So it is better to waterproof polypropylene
Q:What is the meaning of the node and the additional layer in the construction of the membrane waterproofing layer?
In general, these places are also the most vulnerable areas, need to focus on processing.
Q:What kind of waterproofing membrane, waterproofing membrane is how to classify their respective advantages?
SBS Asphalt membrane: low temperature waterproof material will crack, the high temperature of the material will become liquid flow. PVC waterproofing membrane: Over time, the plasticizer will be displaced, and can not be re-welded, must be replaced with new materials.
Q:What is the use of waterproof membrane?
Building waterproofing membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc., to withstand external rain, groundwater leakage can be curled into a roll of flexible building materials.
Q:Asphalt waterproofing membrane and polymer waterproofing membrane
One of the elastic modified asphalt waterproofing membrane on behalf of the product is SBS modified asphalt waterproofing membrane; plastic modified asphalt waterproofing membrane on behalf of the product is APP modified asphalt waterproofing membrane.
