PondTechnology protection fabrics are custom-made tough synthetic non-woven fabrics used above or below pond liners to prevent puncture from rocks, roots, and soil debris. Liner Protection Fabric is recommended for use under any rubber liner: unlike sand bedding, carpet padding (never use old carpet!), and other fabrics, it can protect against puncture from above the liner by limiting how much the liner can stretch under pressure. When pond liners are to be completely covered with soil, gravel, rocks, or concrete, Liner Protection Fabric should be used both above and below the liner. Boulder Padding is a super-thick protection fabric recommended for use under large boulders and other concentrated loads.
LINER PROTECTION FABRIC: PondTechnology Liner Protection Fabric is a light gray, non-woven polyester fabric designed with optimal characteristics for preventing liner damage. It also is designed to allow lateral gas transmission to reduce the likelihood of liner bubbles due to deterioration of organic debris. At nearly one-eighth inch thick, it is substantially thicker than fabrics commonly used for landscaping and soil filtration, yet is extremely flexible. Unlike less-expensive fabrics, it is scanned for metal debris from manufacturing that could damage soft rubber liners. Since it does not deteriorate under a wide range of soil pH and is essentially non-biodegradable, it should last indefinitely. We offer two standard rolls – 5 ft x 100 ft and 7.5 ft x 100 ft – and wlll cut either to any length. For large projects, we can supply 15 ft x 300 ft and 15 x 1200 ft rolls.
INSTALLATION OF LINER PROTECTION FABRIC: Simply spread the fabric over the excavation, folding and pleating as necessary to obtain a good fit. Overlap adjacent sheets of fabric six to twelve inches and spread sand over the joints so the fabric will stay in place when the liner is dragged over it. When installing large liners it is often better to lay the rubber in place first and then fold back sections of the rubber to install the fabric.

BOULDER PADDING: PondTechnology Boulder Fabric is a dark gray, non-woven polypropylene fabric measuring approximately three-eights of an inch thick, designed to reduce the chance of liner damage from very heavy objects. Since it does not deteriorate under a wide range of soil pH and is essentially non-biodegradable, it should last indefinitely. We stock rolls measuring 6.5 ft x 49 ft and will cut any length.
