HDPE liners (Geomembranes) are produced from High-Density Polyethylene resin. The manufacturing process involves film-blowing, adding carbon black, antioxidant, anti-aging, and UV-resistance components to form a sheet.
usage
Water Harvesting using dam liners is slowly becoming a reality because of the ever changing climate and lack of water. Water harvesting using dam liners will go a long way in providing water for irrigation, animal use, industrial use and fish pond liners for fish farming.

advantages
- Good dam liners must be UV treated to increase longevity. Quality dam liners can last between 10-30 years depending on the thickness and gauge.
- They should be made from virgin materials, not recycled. Recycled dam liners have very short lifespan and tend to crack within 1 year.
- They materials should be highly resistant to abrasion and puncturing.
- They should be easy to work with.

How to install geomembrane dam liner
● The surface must be inspected immediately before the liner is placed. Any debris that could damage the liner or prevent an even/smooth deployment must be removed.
● The deployment of the rolls should be in a manner that will require the least amount of welding.
● The rolls are placed as pre-determined in the blueprint or design.
● If the lining is going over a slope it is laid vertically up and down the slope. Additionally, material that is deployed on a slope should be carefully unrolled and not simply unrolled freely downhill. On slopes that are curved, material may require a diagonal cut in order to ensure welds are perpendicular.
● The installers will take careful precautions to prevent wrinkling
● Anchor the linings as they are laid. Usually sandbags or tires are used.
