In fact, HDPE liners are designed to last for over 100 years and are globally accepted as the best material to use for agricultural, civil, and construction applications, especially because they provide:
When choosing between HDPE and rubber liners the most important factor to consider is how the materials are seamed together. Rubber liners tend to be glued or taped together, while HDPE liners are welded. Adhesives can deteriorate over time compromising the integrity of the join and security of the bond.
Wedge or fusion welding is recognised as the premier method of joining geomembranes, as each weld can be tested to ensure that a complete and uncompromised seal has been achieved. The process uses heat and pressure to create a double-track weld along the length of overlapping sheets of HDPE. The cavity between the sheets is then sealed at each end and pumped with air until it reaches 2.5 bar. If the air pressure holds without dropping more than the allowable 10% over 5 minutes, the seam is deemed to have passed. If not, failures in the weld are repaired by locating the point out of which the air is seeping.
It is this technique combined with daily onsite equipment calibration that enables I.S. Dam Lining to provide you with secure containment solution.
There are a variety of geomembrane liners, each suited to a different application. We can advise you on the best liner for your project, specific to size, shape, depth, purpose and terrain. Other factors in product selection include geomembrane density, tensile strength, UV durability and chemical resistance. You're guaranteed a long-lasting quality result.
