PVC Liners

PVC liners have been successfully used for containment applications since the 1960's. PVC geomembranes have proven especially effective in dealing with limited site access, long haul distances and areas where freeze and thaw are an issue. One of the largest current applications for PVC geomembranes is the containment of hazardous and municipal wastes and their leachates. PVC geomembrane are very flexible and can be factory fabricated into large panels to reduce field seaming. However, they are also easily seamed in the field by using PVC glue. Critical applications may require heat welding in the field by a certified technician.

Polyethylene Liners

Polyethylene liners (HDPE, LLDPE) offer superior strength and are resistant to chemicals and puncture.

LLDPE (Linear Low Density Polyethylene) creates a flexible liner that conforms well to any surface. A big benefit of LLDPE is its ability to be fabricated into large panels that can be accordion folded and rolled, making deployment in the field much easier than HDPE. LLDPE can also be heat-welded in the field by a certified technician. LLDPE is available in standard 22’ wide rolls or custom panels and in thicknesses from 20 to 120 mils. Finish options include smooth or textured on one or both sides.

HDPE is rigid, tough, has high UV protection and is very resistant to a wide range of chemicals.

HDPE is available in standard 22’ wide rolls and in thicknesses from 20 to 120 mils. Finish options include smooth or textured on one or both sides. Unlike LLDPE, HDPE does not ship in custom panels due to its tendency to develop stress cracks when folded. HDPE requires certified technicians heat weld the rolls in the field.

Geomembrane Liners Used in Hydraulic Fracturing "Hydrofracking" or "Fracking"

Oil and natural gas production (O & G) is a fast-growing segment of the geosynthetic materials market. The development of hydraulic fracturing or "fracking" to reach difficult to extract oil and gas reserves in the U.S. has led to a boom in O & G production. The scope and range of geosynthetic material specifications for fracking sites will vary depending on region, climate, site conditions, environmental and safety regulations.

There are four main applications for geomembrane liners at fracking locations: pad liners, secondary containment, impoundments and floating covers. Pad liners have typically consisted of 24-40 mil geomembranes. Secondary containment typically involves a 24-30 mil geomembrane and nonwoven geotextile. Materials typically used in impoundments range from reinforced geomembranes to 6-mil black film. But new technologies and techniques for liners in all these areas are being introduced rapidly. Floating covers are made by sandwiching a sheet of foam board between two sheets of 24-40 mil LLDPE or a woven, coated PE geomembrane.

Recently, LLDPE liners have seen heavy use in "fracking." Linear Low Density Polyethylene liners are malleable, tough and respond well to the cold temperatures seen in areas where fracking is occurring. 30 - 40 mil LLDPE single-sided textured and smooth liners and 36 mil scrim-reinforced single-sided textured LLDPE liners are used on rig pads and as pit liners, frac liners, reserve pits and pond liners.
