Facts About The Selection And Use Of HDPE Landfill Lining
landfill CQA - A safe or sanitary landfill is a carefully built hole below ground, or built on top of the ground, into which wastes are put. The target is to avoid any hydraulic connection between the wastes and the surrounding environment, particularly groundwater. Basically, a landfill is a tub in the ground , a double-lined landfill is one tub inside another. Bathtubs can leak in 2 ways : out the bottom or overboard. HDPE landfill liners are the most popular choice for lining landfills internationally and the best HDPE lining systems are typically "composite" systems with a combination of HDPE surface above a clay type material for additonal protection.
landfill CQA - GUNDLE geomembranes were one of the first manufactured and are produced using high density polyethylene ( HDPE ). GUNDLE is produced in various thicknesses and with either smooth or structured surfaces.
Legislations in numerous states around the globe have driven the marketplace for landfill liners making waste containment the single biggest use for HDPE liners. HDPE landfill liners are usually cost-effective, have excellent chemical resistance to most chemicals, and have anticipated maunfacturer quoted lifetimes ( in a properly designed and constructed landfill ) of centuries. Dependent on the level of containment needed HDPE can be combined with other lining materials ( or other HDPE layers ) to form multi-layer landfill liners for unsafe waste applications. HDPE is on occasion used in landfill caps however a low friction angle limits its application on sheer slopes.
The manufacturers claim that world experience of HDPE application affirms durable life span of HDPE geomembranes, not less than fifty years.
The high density polyethylene membranes are typically made of 97.5% polyethylene, 2.5% carbon black and other stabilizers for UV protection, ageing protection, antioxidants. The product does not contain softening agents that could migrate in time.
There are nevertheless plenty of other geomembranes like Puraflex. Puraflex is a real example of a new hydrocarbon and chemical resistant barrier membrane designed for containment, separation, environmental and groundwater protection projects. Its proved resistance to hydrocarbons and dangerous industrial chemicals provides a cost-effective solution for brownfield developments.
