How to Build a Watergarden Using a Flexible Liner

The attraction to water is in each and every one of us. We are surrounded by water in New Zealand, but busy lifestyles do not always allow us to take advantage of beaches, lakes and rivers. So now, more than ever, New Zealanders are creating water views in their own gardens, with features that range from simple bird baths to garden ponds and fountains. At Palmers you can get all the water garden products you need as well as plenty of friendly, expert advice.

Planning
Outline the shape of the pool on the ground with a garden hose or rope and adjust until it resembles the shape you had in mind. Simple shapes are best and look more pleasing when finished.

Plan the type of edging you require as this may affect the size of liner sheet you require. Calculate the size of liner you need. Length is maximum overall length of the pool plus twice the maximum depth. If you intend to take the liner underneath edging stones, you must include this area in your length and width.

Digging
Dig down to shelf level and then dig out the centre down to the full depth adding 5cm all round for a sand layer under the liner. Ensure angles are correct and the sides and shelves are smooth. Prepare for your edging.

Checking
Ensure that the top of the hole is level all round. Check for sharp stones or roots and remove any you find and fill the holes they leave. Cover the whole surface with a 5cm layer of damp sand, Liner, Underlay or old carpet.

Filling
Stretch your flexible liner over the hole and position it so that the pool is centred. Allow it to lay in the hole so that it just touches the bottom and the shelf edges. Hold it in position with smooth stones round the top.

Start filling with water. It will stretch to fit the hole and it will form pleats in corners and curves. Tidy any pleats and they will hardly be visible once the pond is full. Stop filling when the water is 10cm below the top.

Edging
Now work on your planned edging. There are three basic types (rock edging, marsh edging or slab edging) which you can vary or mix as you wish. In each case, the edge of the liner is protected from the sun's ultra violet rays and the finished result looks neat. Now finish the surrounding landscaping with waterfalls, rockery or paving.
