Factory Direct HDPE LDPE LLDPE PVC EVA Geomembrane Thickness As 0.2mm To 3mm For Underground Detention And Retention System
Product Description：
EVA geomembrane is one of geomembrane series products. EVA is ethylene-vinyl acetate copolymer, which has good flexibility, elasticity, weather resistance, environmental stress cracking resistance and bonding performance.All mechanical indexes are higher than those of ordinary polyethylene. It’s very convenient to be used in construction and performs good when welding.
Performance Characteristics：
1、No chemical additives, and no heat treatment, is the type of building materials.
2、Have good mechanical properties, good permeability, and can resist corrosion, anti-aging.
3, has a strong resistance to burial, corrosion resistance structure fluffy, with good drainage performance.
4, has a good coefficient of friction and tensile strength, with geotechnical reinforcement performance.
5、It has the functions of isolation, back filtration, drainage, protection, stability and strengthening.
6, can adapt to the uneven grass-roots level, can resist the construction of external damage, creep is small.
7、Good overall continuity, light weight, easy construction.
8、It is permeable material, so it has good anti-filtration isolation function and strong puncture resistance, so it has good protection performance.
Role Use：
Mainly used in landfills, sewage waste treatment, water conservancy, agriculture, transportation, high-speed rail, tunnels, airports, airports, buildings, landscape and other anti-leakage lining projects.
Construction Program Specification:
Geomembrane should not be dragged and tugged during transportation to avoid stabbing by sharp objects.
1. It should be extended from the bottom to the high level, do not pull too tightly, and should leave a margin of 1.50% for local sinking stretch. Considering the actual situation of this project, the slope takes the laying order from top to bottom.
2. the longitudinal joints of two adjacent widths should not be on a horizontal line and should be staggered by more than 1m from each other.
3, longitudinal joints should be more than 1.50m away from the foot of the dam and the foot of the bend, and should be located on the plane
4. side slopes first and then the bottom of the field.
5、When the side slope is laid, the direction of spreading the film should be basically parallel to the great slope line.
Product Specifications:
0.3mm~3mm, width 1m~8m, length according to customer requirements.
