For larger ponds and lakes, consideration for erosion and wave action should be taken into account. The use of rip-rap, concrete shore protection or synthetic erosion control protection is highly recommended.

Slopes should be limited to 3:1, and cover soils should be walked in from the bottom of the pond to the top, always keeping a minimum of 12" of clean soil between your equipment and the membrane.

A PVC liner can be easily installed by unfolding the liner into the pond and seaming the panels using adhesives or wedge welders. Your liner can be installed using customer provided labor and a CLI supervisor or in a turn key installation provided by one of CLI's professional, certified crews or affiliate installers.

  Design Notes
Since PVC is degraded by sunlight; it requires being covered with a minimum of 12" (1 foot) of clean fill to function as designed. In prolonged exposure to sunlight, PVC must be covered before warranted for lifespan. In buried applications, PVC can provide a service life of over 20 years.

Now, with advanced technology in field welding, the use of wedge welders that apply heat and pressure to form a homogenous weld are becoming the state-of-the-art. Wedge welding provides excellent seam properties and reproducible welds and is faster and cleaner than solvents.

  Installation of PVC
PVC supports diverse field seaming capabilities (thermal fusion by hot air wedge welders or chemical adhesives). The most commonly used process is solvent welding, which is very similar to welding pipe and basically melts the adjacent panels together.

Fabrication
PVC material is delivered in rolls to CLI who takes the 6-8' wide materials and fabricates them into large panels for delivery to the project site. PVC can be fabricated into panels of up to 25,000 sf and shipped to a site for installation. The use of large fabricated panels allows field installation crews to install acres of lining per day while limiting the number of field seams.

PVC is available in a variety of formulations including fish grade and oil resistant. It is available in 20 mil, 30 mil, 40 mil and 60 mil.

The use of a PVC geomembrane liner prevents contaminants from entering groundwater sources or streams. In addition, it conserves potable water resources by preventing seepage loss.

Because of its high flexibility, PVC liners readily conform to subgrade contours and offer excellent interface friction without being textured.

PVC has high puncture strength and excellent abrasion resistance. It is resistant to a number of industrial chemicals.

Description
Poly Vinyl Chloride (PVC) is the most commonly specified lining material in the industry. Manufactured by the calendaring or extrusion process, it is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane liner with many uses and advantages for the user.
