Pre-formed ponds are great for smaller areas, where forming a shape using a flexible liner would create numerous folds which could look unsightly.
An informally shaped pre-formed pond is an ideal habitat for plenty of wildlife and plants along with a few fish.
The pre-moulded pond is especially suitable for small water gardens! It has a strong, thick side wall, which makes it possible to keep the pond quite deep in a small area. We provide a 15-year guarantee on all our pre-moulded ponds.
Most pre-formed ponds have a natural shape, although symmetrical, round and square ponds are also available for a more formal garden. Virtually all of them have a marsh edge and various planting levels. If you want fish in your pond, make sure that the pond you buy is at least 80 cm deep so that during a normal winter it won’t freeze completely.
If your plan your pond beforehand, installing a pre-moulded pond is easy to do yourself. This site gives you step-by-step instructions on how to create your own pond.
|Creating a pre-moulded pond
Place your pond in your chosen spot and mark around the outer edge with posts. Mark on the ground where the deeper part of the pond is to be.
Begin by digging out the deepest part. Then model the marsh zones (the shallowest pond areas) and finally the marsh edge. The hole for the pond must be approx. 10 cm wider and deeper than the actual pond form, as the pond is to be settled into a layer of sand. Remove stones and roots from the hole and spread a layer of sand approx. 10 cm thick in the hole, stamping it down well.
Place the pre-moulded pond in the hole and set it level, checking from various points. A plank placed across the pond is a useful way to check it is horizontal. In order to settle the pond into the sand, you must fill the pond by 1/3 so that it will not float upwards.
Once the pond is level, fill the gap between the hole and the pond form with sharp sand. Then wash the sand down with plenty of water using a garden hose, so that the pond will not sink down later to one side or the other. Alternate with a layer of sand, wash down, layer of sand, wash down etc., waiting each time until the water and sand have sunk down around the pond. Check regularly that the pond is still horizontal. Fill the top 10 cm with good topsoil for later planting. Finally, fill the pond itself with water.
Pre-formed pools must have all round support, ensure you have created a sand bed for the pool to sit on and pack sand down between the excavation and the pool sides.
