Flexibility
Rock-on-a-Roll is very thin and very flexible. It conforms to any shape and can wrap around the edge of a preformed liner.

Size and weight
All rolls of Rock-on-a-Roll are 34 inches wide. They are available in lengths of 8 feet, 16 feet, 24 feet, 32 feet and 40 feet (multiples of 8 feet). The thickness of Rock-on-a-Roll varies somewhat, but it is about the same thickness as pond liner. An 8 foot roll weighs about 5 pounds and the longer rolls weight proportionately more.

Where to use Rock-on-a-Roll
A pond's bottom will become natural looking on its own over time, so Rock-on-a-Roll isn't usually needed there. It's the sides of the pond (and streams) that often present a challenge. Stacking rocks may be difficult, expensive and unstable, and that is what Rock-on-a-Roll is really designed to help with.

Installing Rock-on-a-Roll

Rock-on-a-Roll can be installed either with the pond emptied of water, or with water in the pond. In general, it is easier to install without water in the pond .
Rock-on-a-Roll does not float. However, it has a certain amount of "body", so if it is going around curves it may not lay flat. We recommend holding along the top and bottom edges with stones, plant pots or whatever is practical. If that is not possible, it can be glued. Non water-based contact cement can be used, as can polyurethane expanding foam (Great Stuff), silicon glue, or any other waterproof adhesive.
Rock-on-a-Roll is very easy to cut using a utility knife. It may dull scissors.
Rock-on-a-Roll is not meant to hold water. It is designed to be installed over an impermeable liner. However water will not flow through it like it would through a piece of cloth, so it will direct water in a stream or waterfall.
Seaming is usually not needed. In most water features the pieces can be overlapped, with a few stones placed to hide where they meet.
IF adhesive is needed, fish-safe options include 100% silicone caulk or pond foam (polyurethane foam commonly used to adhere stone to liner).
Adhesives not explicitly described as fish-safe include contact adhesive (spray or paint-on), which is convenient because it creates an instant bond so it does not need to be held in place.
