Just Liners PVC is a synthetic vinyl, highly flexible stable material that is not only easy to work with, but is long-lasting and aquatic safe. The flexible 22 and 35 Geomembrane liners are fabricated to fit each customer's specifications. PVC is a highly stable material that is formulated for safety when exposed to fish and plant life in a decorative pond. It is is also recyclable. It stays flexible in temperatures from -22° Fahrenheit to 120° Fahrenheit making it easy to install year round. PVC is light in weight and easy to lie in place. It will mold to the unique contours of your pond, allowing a more creative design. These liners are custom cut for your pond dimensions. It is not a crystalline product, making it highly resistant to ozone degradation. However, it is susceptible to ultraviolet (UV) degradation and must be completely covered against exposure to UV rays. This is standard procedure with pond liners because it is desirable to hide them from view. PVC's high expansion and contraction characteristics will enable it to conform to objects in the sub grade. The tensile strength will allow it to stretch 300 percent. It has 200 pounds per inch (90kg per 2.5cm) of tear resistance. PVC requires little or no regular maintenance once installed. However, if repair becomes necessary, it is easy to do without removing the liner from the pond. After the initial pond installation, keep any excess material for patching and purchase our HH-66 adhesive. PVC installs easily and quickly. It is easily seamed so that, for unusually large areas, two or more rolls can be locked together to make a strong weld.
