HDPE dam liners are made from high grade polyethylene raw materials, adding carbon black and antioxidant, anti-aging, UV-resistance components
Products Description
We offer high quality dam liners made of reinforced polyethylene that prevent water loss through soil infiltration.
We use geosynthetic and geomembrane fabrics to build long-lasting dam liners with high resistance to abrasion and punctures and high UV resistance. Geomembranes are low-permeability synthetic membrane liners or barriers used in man-made dam projects with earth-related materials such as water and gas transfer.
Dam liners are a worthwhile investment for conserving and storing water. Dam liners reduce water loss through suction and evaporation. There are some temporary methods to prevent water loss, such as sealing cracks, but the best and most durable solution is a dam liner. It also prevents contamination inside and outside the dam.
am Lining Applications
Irrigation ponds, canals, ditches & water reservoirs
Aquaculture
Heavy duty industrial applications
Leak-tight fuel establishments
Any leak proof facilities
advantages
The most chemically resistant member of the polyethylene family due to its dense configuration.
High resistance to shear stress
No need to cover the liner because it is UV stable
Non-water releasing encapsulations
Non toxic
Available in roll stock and come in varying thicknesses ranging from 0.3 – 2mm
Field welded with hot wedge welders and extrusion welders.
