Level Edging

Pre-Formed Ponds: 

After excavation, cover the base of the hole, with about 5cm of sand and level out, position pond on the sand and place a spirit level across the top lips of the pond, reposition and add sand as necessary to achieve a level pond. Then gradually fill the pond while back filling the sides. Do check manufacturer’s instructions for specific installation information.  

Liner Ponds: 

Once your pond is excavated, consider the edging method you’re going to use.
For a basic or wildlife pool edge, simply knock a stake into the centre of the excavation (The stake will need to be at least 15cm deeper than the pool, so when it’s knocked into the soil it won’t move). Then drive the stake in until the top is at the desired finished pool level.

Now simply  position a length of straight timber across from the stake to the side. Position a spirit level on the straight timber. Then work your way around the pond removing or building up the edge, creating a perfect level all the way around.

Should you wish to build a more complex edging, you will need to lay footings and these must be laid level and at least 10-15cm deep. (See "Edging Methods")

To achieve this, firstly  position a central stake as above, but this time the top should be at the finished level of the footing. Now take your straight (bridging) timber from the central stake to where the footing is going to be laid on the side. Here take a peg approx. 30cm long and  partially knock it into the soil. Then place the bridging timber across and check the level and if required continue to knock the peg in further until the bridging timber is level. Carry this on around the pool placing pegs every 50-100cm apart. Once completed ensure all the pegs are at least 10-15cm proud of the soil; if necessary remove some more soil around the pegs.

Once these pegs are all in position, simply lay the footings to the top of the peg and this will leave you a perfect level footing all round your pool.  

Note: With all ponds, you must not place heavy edging around for at least a week, to allow the pond to settle.
