Geomembrane HDPE
Pond Liner Geomembrane is the kind of HDPE geomembrane liner which is the ideal geosynthetic material used as the anti seepage lining system for fish farm pond. The pond liner geomembrane has good waterproof properties to preventing water from leaking into the surrounding sediment. Most types of ponds will require a pond liner to be installed, as well as a quality underlayment for pond liner support. High quality pond liner geomembrane is the HDPE pond liner which is is made of finest quality high density polyethylene (HDPE) with specially formulated, virgin polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components, which makes our pond liner geomembrane with excellent resistance to UV radiation and is suitable for exposed conditions. HDPE geomembrane pond liner is also specially engineered to withstand general wear and tear, as well as impact and pressure which can cause leaks.
Description:
HDPE GEOMEMBRANE INSTALLATION. The geomembrane cannot be dragged and pull to avoid hurting by shrp objects during carring, 1. It should be extended from bottom toward the top,cannot 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 level line,should be staggered over 1m. The overlap should be over 20cm. 3. The joints in the machine direction should be over 1.5m apart from the foot of dam,turn,should be located at the plane. 4. Laying order: first slope then bottom of site 5. The direction of extened geomembrane should be basically parallel with the line of maximum slope when laying the slope.
