Main Features

  1. HDPE as raw material used for food packaging bags and plastic wrap. Non-toxic and suited for fishes. 2. Temperature adaptability: -70℃~110℃ 3. Excellent anti-UV and anti-aging properties which can be exposed for a long time. 4. Puncture resistance. 5. Elongation≥700%. ground settlement and movement won't affect the waterproofing performance. 6. Resistance to mildew & bacteria,good resistance to alkali & acid. service life up to 50 years. 7. Geotextile can protect Geomembrane(HDPE) from sharp material,UV and extending its service life.   8. Welding construction, no primer and heat needed.    

Where to use

  1. earth-rock dam, rockfill dam, concrete dam,tailing dam, sewage dam, reservoir dam ect 2. Subway, basement and tunnel 3. Road and railway subgrade 4. Garbage field and artificial lake    

Package and transportation

  1. Membranes should be stored under dry and ventilated conditions. 2. Different types of membranes must be piled separately. 3. Under usual condition, storage period is one year since production date. 4. Membrane roll should be put vertically during transportation. It should be kept away from sunshine and rainwater.
