HDPE geomembrane lining material is an ideal material for large applications that require UV and ozone resistance, chemical resistance, or high-quality installations. It is typically used in landfill and mining applications. Generally it is available in various thicknesses ranging from 40 to 120 mil. These materials are very suitable for exposed lining projects.
The HDFE pipes include approximately 2% to 3% carbon to protect against ultraviolet radiation. The HDPE pipes are backfilled with water prior to the survey in order to conduct seismic energy from the seismic source placed in one hole to the hydrophone strings placed in the other two holes. HDPE pipes are recommended over PVC pipes because they tolerate cold better and do not need protection from sunlight. HDPE pipes are used extensively for the transportation and distribution of natural gas, with over 80% of the new piping installations using HDPE.
