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.
(If the geomembrane must be exposed to direct sunlight, please look at other products for resistance to UV)
roots or vegetation bother a PVC liner?
PVC liners resist root penetration. However, some vegetation could penetrate the liners. This can be avoided by sub grade soils prepared to be free of roots and organic material.
(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.
does chemical resistance mean?
A PVC liner will survive exposure to a large variety of chemicals, even though the chemical could have some effects on the liner, without causing the liner to fail. If you have a specific concern, give us a call at 800-524-8672.
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.
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.
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.
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.
