GEOMEMBRANE LINERS

Geomembrane liners are impermeable membranes that are ideal for a variety of primary and secondary containment applications. They are available in a wide range of physical, mechanical and chemical resistance properties. They also offer superior containment and protection for solid waste and water containment, mining, and oil and gas containment applications. In addition, they play a key role in environmental remediation projects. They are a reliable and cost-effective solution to your containment needs.

LLDPE-LINEAR LOW DENSITY POLYETHYLENE

FEATURES

LLDPE is a flexible geomembrane liner that conforms to any surface even in cold temperatures.  In addition, it has high elongation, tear resistance and burst strength properties.  Also contains carbon black and UV stabilizers to enhance longevity and outdoor performance.

SPECIFICATIONS

Available in 22’ wide roll goods in thicknesses of 20 mils to 120 mils.  They can also be smooth or textured on one or both sides to improve friction.  Due to its flexibility, LLDPE can be factory fabricated into large panels.  Accordion-folding and rolling the panels offers economical deployment in the field.  In addition, the panels can be smooth or lightly textured on one or both sides.  Although weight limits the panel size, we can often fabricate a panel large enough to eliminate the need for field seams.  Factory fabrications range from 6 mils to 40 mils in thickness.

INSTALLATION

If the material requires field seaming, certified technicians heat-weld the rolls in the field.  This provides a high quality, test certified installation.  If you require installation services, please call us at 609-971-8810. We work with a network of experienced and certified geomembrane installers.

HDPE-HIGH DENSITY POLYETHYLENE

FEATURES

Rigid tough geomembrane liner that is highly resistant to a wide range of chemicals due to its density.  Material also does not require soil cover.  It can be left in an exposed environment due to its high UV protection against degrading and low temperature brittleness.

SPECIFICATIONS

HDPE  typically delivers to the site in 22’ wide large rolls.  They are available in smooth or textured on either one or both sides to improve friction.  Available thicknesses range from 20 mils to 120 mils.  HDPE does not ship in custom panels due to its tendency to develop stress cracks when folded.

GEOSYNTHETIC CLAY LINER – GCL

FEATURES

GCL’s are composite liners that are manufactured by sandwiching thin layers of bentonite clay between two geotextiles.  They can also be bonded to a geomembrane to form a very thin, tight hydraulic layer.  Needle punching or stitching the bentonite between two geotextiles internally reinforces the bentonite while increasing the shear strength of the material.  GCL’s also function as a containment material by forming a hydraulic barrier layer to liquid movement.

SPECIFICATIONS

Geomembrane supported GCL’s are available with either HDPE or LDPE textured or smooth liner in thicknesses from 15 to 80 mils.  Rolls are 15.5’ wide with varying lengths. Geotextile supported GCL’s are available with either a woven or non-woven or combination of both. Typical geotextile weights range from 3oz -6oz.  Roll Size is 15.5’ x 150’

INSTALLATION

An experienced, manufacturer-approved certified installer typically performs the installation.  The installer overlaps the GCL seams and then seals them with accessory bentonite.  Penetrations or repairs also require accessory bentonite.  If you require installation services please call us at 609-971-8810. We work with a network of experienced and certified geomembrane installers.

PVC-POLYVINYL CHLORIDE

FEATURES

PVC geomembrane liners are extremely contractor friendly while offering many advantages over other liners.  Highly flexible to easily conform to sub-grade contours.  Excellent interface friction properties without being textured. Excellent puncture as well as abrasion resistance.  Superior chemical resistance to acids, alkalis, and alcohols. However, covering the material with soil is necessary to protect the liner from exposure to sunlight.  It also loses flexibility in cold weather applications.

SPECIFICATIONS

Available in a variety of formulations such as reinforced, potable water, fish grade and oil resistant. Factory fabrications into custom panels in thicknesses ranging from 20 mils to 60 mils are also available.

INSTALLATION

PVC can be self-installed in the field by using PVC glue or solvent.  However, critical applications may require heat welding in the field by certified technicians to ensure a high quality, test certified installation.  If you require installation services, please call us at 609-971-8810. We work with a network of experienced and certified geomembrane installers.

WOVEN COATED REINFORCED POLYETHYLENE- RPE

FEATURES

Woven coated reinforced polyethylene geomembrane liners are made by weaving polyethylene tapes and then coating them on both sides with UV resistant polyethylene.  This process produces a lightweight geomembrane material that is highly resistant to punctures and tears.

SPECIFICATIONS

Available thicknesses range 8 mils to 30 mils.  Material is available in black, silver, or white.  Due to its light weight, woven coated reinforced polyethylene can also be factory fabricated into very large custom panels.  Accordion-folding and then rolling onto a core allows for easier handling and time-saving installation.

INSTALLATION

Large panels may eliminate the need for field seaming or sewing.  Most often taping is sufficient for temporary or non-critical applications.  However, if the material requires field seaming, certified technicians can sew or heat-weld in the field.  If you require installation services, please call us at 609-971-8810. We work with a network of experienced and certified geomembrane installers.
