Butyl Rubber Pond Liner (750 micron)

  Ref: 015005000
Installation Instructions
1 Check the pond construction site and the surrounding working area and remove any sharp objects that could damage the lining.
2 Install the geotextile liner protection material laying it to the ground contours with a minimum of 3" overlap between the strips.
3 Position the roll at one corner of the pond, either on the surrounding land or in the pond. Carefully remove the wrapper and check to see that the roll is orientated in the proper direction. Unroll the liner and then pull it across the pond, flipping it slightly to force air under the liner and let it float into place.
4 Leave at least 6" to 12" on the ground surface, since the rubber will pull back as the pond is filled. Avoid stretching the rubber as you position it. Just let it wrinkle and pleat naturally to fit the contours of the pond. If the side walls are steep it may be necessary to use a few smooth stones as weights to keep the liner from sliding into the pond.
If the liner is not being covered omit steps(5) and (6)
5 Position the second layer of geotextile liner protection above the liner.
6 Place the pond liner covering material (soil, sand or stone) working from the centre of the pond outwards to the anchor trench.
7 Fill the pond with water, letting the liner slip freely into the pond and mould to the contours of the pond without stretching. Any stones or other weights used to temporarily position the liner must be lifted periodically as the water level rises. This is very important because permanent stretching can shorten the life of the liner when the pond is full.
8 Any excess liner material or liner protection geotextile should now be trimmed ensuring sufficient remains for anchoring.
9 The pond liner should then be anchored permanently (by backfilling the anchor trench or completing with pond stone edging).
10 Leave pond for one week before introducing any fish.
