Black color ASTM GR13 HDPE Geomembrane 100% virgin material made
For Saltworks
Description :
YIXING Shenzhou brand HDPE geomembranes are a kind of large
molecule (macromolecule) polymer as the basic raw composed of
waterproof and cut- offs(insulation & separation) geosynthetic
material
Type: HDPE geomembrane, composite geomembranehigh strength. low
permeability. chemical corrosion resistance. ultraviolet & sun
exposure resistance. oxidation resistance, weather resistance,
antimicrobial, erosion resistance.
HDPE Geomembrane Feature
1. Without chemical additives and without heat treatment, it is a
friendly building material
2. It has good mechanical properties, good water permeability,
anti-corrosion and anti-aging
3. It has strong anti-burial and corrosion resistance, fluffy
structure, and good drainage performance
4. It has a good friction coefficient and tensile strength and has
geo-reinforcement properties
5. It has the functions of isolation, anti-filtration, drainage,
protection, stabilization, and reinforcement
6. It can adapt to an uneven base layer, can resist the damage of
construction external force, and has a small creep
7. Good continuity, lightweight, and convenient construction
8. It is a water-permeable material, so it has a good
anti-filtration isolation function and strong puncture resistance,
so it has a good protective performance

HDPE GEOMEMBRANE INSTALLATION
The geomembrane can not be dragged and pull to avoid hu ing by
sharp objects during carrying.
1. It should be extended from the bottom toward the top, can not
tightly pull, it should keep 1.5% margins for local stretching. To
view actual conditions, the laying sequence from top to bottom is
adopted for the slope.
2. Two adjacent geomembrane's joints in the machine direction
should not be on a levelline, should be staggered over 1 m. The
overlap should be over 20cm.
3. The joints in the machine direction should be over 1.5m apa from
the foot of dam, turn, should be located at the plane.
4. Laying order: first slope then the bottom of site
5. The direction of extened geomembrane should be basically
paraliel with the line of maximum slope when laying the slope.
