Product Description:

HDPE Geomembranes

Products Description

   This product is extruded PE membrane formed by adding anti- oxidant, absorbent of ultraviolet and dyestuff into HDPE or LDPE or EVA and will provide an effective barrier to of liquid

water and water vapor.

Characteristics

·HDPE performs well in mechanical properties ,ageing-resistance , chemical-resistance ,climate- resistance and

resistance to puncture .

·LDPE & EVA feathers great elongation, good flexibility at low temperature, softness and easy

installation.

·ECB ,high-class waterproofing rolls, is formed by combining ethylene polymer with oil-resin.

Q:What is the accounting subject of the waterproofing membrane
Own spare, included in the project materials Waterproof sheet, used for sale, remember inventory goods
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
The second compound is, first produced or bought from the market polyethylene film, by heating the polypropylene non-woven composite up. This method is not enough heating, non-woven stickers are not strong, heating is too high, the polyethylene film damage, polyethylene plastic through the second heating to speed up his aging. Further, the polyethylene film for secondary compounding, the proportion of the recycled plastic is too high, and the anti-aging property is lowered.
Q:The difference between high polymer modified asphalt waterproofing membrane and sbs
SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, the plastic film for the anti-sticking isolation Layer, by the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production.
Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing
In the use of polyester coil with several other waterproof materials used in conjunction with: 1, the node (lap, at the mouth) to strengthen the treatment, usually using polyurethane waterproof coating (that is, the usual "911" waterproof coating);
Q:What are the advantages and disadvantages of waterproofing membrane?
The waterproof membrane study its drawbacks: waterproofing is performed when the amount of coating material according to the cross-sectional shape of the waterproof base waterproof construction, the need for a complex shape of the base layer a plurality of splicing, waterproofing overlap each other at the bonding difficult than Large, due to the impact of multi-block splicing waterproof layer of beauty; then completely absolute seal will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with a few decades durable for a long time, but the country is still less matched the binder, and the binder material itself due to environmental factors such as loss of adhesion is often ahead of function, thus leading to the failure of the waterproof self-evident; Furthermore Waterproof membrane after the construction of the protection and leakage after the maintenance is also a problem, exposed waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and the grass-roots bonding, whether full of shops, shop, shop air, between the base layer and the web would be to go aqueous layer, regardless of any part of the cross-cutting breakage, degumming, drooling (even the only one), the entire coherent thereto waterproof power level Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
Q:What are the requirements for the storage of waterproofing membranes?
Waterproof membranes are generally flammable, so the storage area prohibits fireworks.
Q:Coil waterproof roofing requirements
4, the female wall to leave a waterproof membrane head groove, the height of the project after the completion of the requirements of more than 300 flood height, the general height of 400-500 is appropriate.
Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Waterproof construction methods are generally reflected in the construction drawings. If not, please consult the designer. A waterproof, full of sticky. Secondary, sticky or sticky. Construction waterproof with waterproof material. According to each of the different basement waterproofing, the construction team will have its own waterproof concept and specific construction requirements.
Q:SBs waterproof cold sticky how to do?
3, the node sealed processing. To be the primary treatment agent after drying, the first outlet, the root of the pipe and other vulnerable parts of the leakage, in the radius of 200mm range, even brush a layer of adhesive, brushing thickness of about 1mm is appropriate. Paste a layer of polyester fiber after the non-woven fabric, and in the non-woven cloth and then brushing a 1mm thick adhesive. After drying to form a layer of sealing layer.
Q:How to use self-adhesive waterproofing membrane?
Construction Technology of Double - sided Self - adhesive Waterproof Coil First, the empty shop self - adhesive waterproofing membrane (mainly applicable to the basement floor and other suitable for the empty parts of the waterproofing works. Construction process: grass-roots treatment - → node strengthening treatment - → empty sheet - → long, short side lap bond - → quality acceptance 1) grass-roots treatment: grass-roots should be smooth, solid, no clear water, the grass-roots protrusions clean. 2) node to strengthen the processing: the node at the regulatory requirements to strengthen the treatment. 3) empty shop coil: coil length, short side of the overlap width of not less than 60mm. 4) long, short side lap bond: the length of the coil, short lap edge of the isolation film removed, 5) Adhesive on polystyrene board protection
