How cost effective is PVC?

PVC outlasts and outperforms many traditional materials. Because 50% of its base polymer comes from common salt - an inexpensive, renewable resource - it is also much preferred to substitute materials that deplete natural resources.

Can a PVC liner stand up to sunlight?
A PVC liner covered with at least 12 inches of clean fill will last for decades. It must be protected from exposure to direct sunlight.

(If the geomembrane must be exposed to direct sunlight, please look at other products for resistance to UV)

Will a PVC liner be immune to rodent attack?
While PVC generally does not suffer from rodent attack, it does contain a component source protein plasticizer.

Please note:
(1) PVC contains no compounds that have any nutritional or food value to rodents.

(2) the PVC materials do not contain any "addictive" substances.

(3) It is only possible to "chew" a geomembrane at an edge onto which an animal can grip. The likely reason for an animal chewing a geomembrane is to obtain access to the "other side" for some other reason.

What's all this about smooth and textured?
30 mil PVC or greater already has an embossing on one side, processed during manufacture that provides a controlled pattern. This embossing helps PVC, already known for its flexibility, to conform to and 'grip' the contours of the ground.

Can I install a PVC liner myself?
Garden pond projects and ornamental features can readily be self-installed using adhesives on any liner seams. If you have a large installation or have specific site needs and you need help, we can provide a range of assistance. Don't hesitate to contact us at 800-524-8672.

There are wrinkles when I lay out the liner, is that okay?
Yes, thermal contraction and expansion causes a liner to grow or shrink. The liner should be stretched over the prepared sub-grade and "pulled" taut and "relaxed" but not overstretched.

However, care should be taken to avoid wrinkles in the seam area and around mechanical attachments.

Is installation of PVC weather or climate dependent?
Most of the time, if you can stand the temperature you are working in, so can the liner. Generally, if the temperature is above 104° or below 32° degrees, you can seam your liner if certain precautions are observed. At -25°, a PVC liner becomes less flexible for installation. If you are in doubt, CLI can help supervise installation or fully install your liner.
