Modern preformed ponds are best and easiest for a small garden pond
Preformed ponds can be used as built in ponds or above-ground ponds.
For superb natural effect the best these days are fibreglass preformed ponds. Building backyard ponds becomes simplicity itself.
The very best preformed ponds these days are made from fibreglass and come complete with rock edgings built into the preformed ponds. Such preformed ponds cost the least overall if you want a built in pond. Not only are the total costs of preformed ponds lowestthe difficulty of installing edgings is removed completely. The job is also finished in a fraction of the time it would take if the edging had to be done separately.
If you are contemplating building a water garden or a backyard pool for yourself using a built in preformed pond liner then here is the way to make sure your pool landscaping designs work out in practice.

Planning Pool Landscaping Designs around A Preformed Pond Liner
- Place the preformed pond liner in position and mark out the shape on the ground around it.
- Carefully remove any turf within the shape and excavate to a level soil surface slightly larger than the shape. A long spirit level, or a spirit level with a long straight edge is essential.
- Excavate the shape of the preformed pond liner down to the same depth as the marginal shelf. Then make it one inch deeper (25mm) and 4 inches (100mm) larger all around.
- Check the hole is level, particularly around the edge.
- Place the preformed pond liner in the excavation in its intended positionand mark with a sharp stick or trowel the shape of the bottom of the preformed pond liner in the soil.
- Remove the pool shape and excavate to the full depth of the preformed pond liner plus an inch (25mm). With a bit of adjustment the preformed pond liner will fit like a glove, albeit slightly too large. The preformed pond liner should be sitting just below the level you had intended.
- Remove the preformed pond liner and spread a layer of sand one inch thick over the base and the marginal shelf areas.
- Put the preformed pond liner back in. Ensure the base is firm and level and there is solid support under the marginal shelves. Start to fill it with water.
Whilst the preformed pond liner is filling, push sand into the gap between the preformed pond liner and the soil. The level of this backfill must go in unison with the water filling the pool and the pressure at which it is pushed in should correspond with the pressure from the water in the pool. This is a balancing act in which the sand or water could distort the shape. One German manufacturer used to recommend washing the sand into place in order to consolidate it. Doing this presupposes that the excavation is in fairly well drained soil and that you do not to get carried away with the backwash, otherwise the preformed pond liner just floats out of the hole.
Whatever method in landscaping designs you use, leave the pond there full of water over night to do any settling that might latterly occur, before you attempt any edging. If it shifts - empty it and build up the sand support where it has sunk. Gently ramming down the backfill further at the lowest point can make up tiny fractions in subsidence. If you need to do this dont overdo it because it can buckle up the rim of the preformed pond liner, which you want to keep as flat as possible to take whatever edging you might want to choose to go round it.

The strength of fibreglass preformed ponds allows them to be used for both in-ground and above-ground garden pond installations.
You can also do away with digging completely by buying above-ground preformed ponds. This makes preformed ponds ideal for patio or even indoor preformed ponds.
The alternative to fiberglass preformed ponds are flexible plastic garden pond liners. These garden pond liners need much more attention to detail to complete and require some skills not required for installing preformed ponds.
For larger ponds however (above 600 litres or about 120 gallons) pond liners are the right choice.
