----------------------------------------------------------------------------------------------------------------------------------------------
Product Description:
HDPE liner, resistant to a wide range of chemicals, is not threatened by typical solid or hazardous waste leachates. HDPE liner is also suitable for sludge and secondary containment around chemical storage facilities.
----------------------------------------------------------------------------------------------------------------------------------------------
Product Feature :
HDPE liner which is resistance to UV exposure is further enhanced by the addition of carbon black. Additionally, with the absence of plasticizers, volatilization is not a problem.
-------------------------------------------------------------------------------------------------------------------------------------------------
Usage:
Widely used in the seepage-proofing engineerings such as landfill,sewage&waste residue processing plant,dam,tunnel,building,traffic and environmental protection,etc.

Method of installation
The HDPE was supplied 8m wide rolls of approximately 200m in length. To allow easier installation, reduce labour requirements on site, and reduce the amount of joining in wet and dirty site conditions, some workshop prefabrication was undertaken. Approximately four water authority personnel and three from the supplier were required to install the material, which included welding sections together.
The 200m section was laid and welded in approximately two days. The liner was anchored in trenches along the channel bank and the end treatment utilised geosynthetic clay lining (GCL).
