Composite Geomembrane shower waterproof membrane PVC Self Adhering Membrane
Product Introduction
YunYan brand geo-synthetics is a synthetic resin materials for adding antioxidants, UV absorber, carbon black and other auxiliary materials refined become waterproofing materials, mainly used for geosynthetics work. My company's main varieties are:
1. LDPE (low density polyethylene) geomembrane: The physical and mechanical performance is good, capacity is big. Soft, wide width, low temperature performance is good. Easy construction, no pollution, can improve the reliability of seepage control, reduce the project cost, the price is cheaper.
2. HDPE (high density polyethylene) geomembrane: Its mechanical properties, ageing resistance, resistance to chemical corrosion, environmental stress crack resistance, puncture resistance and other excellent comprehensive performance, the price is more expensive.
3. EVA (ethylene vinyl acetate) geomembrane: Performance is similar to LDPE geomembrane, But its softness is better, price moderate.
4. The ECB (ethylene copolymer with asphalt blending) geomembrane: Belong to the higher grade geomembrane, the price is expensive.
5. Polyethylene fiber composite geomembrane, product varieties are: Polyethylene polypropylene fiber composite waterproof coiled material, rubber polyethylene polypropylene fiber composite membrane waterproofing materials, double-sided fiber composite waterproofing materials, PVC two cloth and one membrane composite geomembrane.

Scope of application
1. Artificial lake, landfill, waste water treatment plants and other waterproof seepage control engineering;
2. The subway engineering, culverts, retaining dam, agricultural and industrial water conservancy and water engineering, etc.;
3. Road, blocking dam, culverts, waterproof engineering such as civil engineering;
4. Underground waterproof, seepage control, moistureproof, also applies to the metallurgical, chemical, environmental protection, mining and other waterproof engineering.
Operating guide
1. tools:
Hot type welding machine
Extrusion welding machine Hot air gun
Ultrasonic welding gun, pressure welding machine air inflation leak detector vacuum leak detector Other commonly tools: scissors, hand grinder, etc
2. Construction conditions:
The temperature between 5 and 40 , no more than five wind no rain snow;
Surface soil foundation should be strong, no tree roots, weeds and hard objects;
Foundation surface should be no water, no masonry block and hard objects, keep the level smooth, clean.
3. Laying construction:
Laying in order, pave and weld at the same time, length of joint avoid appears four layers in a line with some joint;
Laying geomembrane, allowed to have no serious uneven, but can not have folding
The thickness of geomembrane single seam is more than 1.2 mm.
Before welding, full thickness with grinder 45 ° chamfer edges.
Attention
1. All equipment must be put lightly on impervious layer,It is forbidden that heat tool contact with geomembrane;
2.All enter the site person must wear soft bottom shoes, smoking prohibited
3. Cover the protective construction while inspection. If there is damage, must be repaired timely.
Storage and transportation and packing
1. To stay away from heat source while storage and transportation, not long time exposure, and stay away from corrosive chemicals, storage shall generally be in ventilation, cool, dry warehouse,it can’t storage at outdoor for too long.
2. Geomembrane packed in textile bag or other packing materials.
