Flexible Liners:
Using a Flexible liner is generally the most satisfactory way of creating a pond which is large enough to house numerous aquatic plants and various fish. You will not be limited to the range of sizes and shapes of Rigid liners offered inside the catalogues and at the garden centres. The transportation and handling can also be a whole lot easier. Price should not be a stumbling block because on an equal area basis, a top quality Flexible liner isn't dearer than a fibreglass Rigid liner.
The only real drawback using a Flexible liner is that you can not achieve the superbly smooth surface and angles that you might find in a pre-formed style of liner. There will be also a few wrinkles, but this should not pose any serious problems.
Plan on starting the task in the spring and during a reasonably dry spell of weather if you happen to be lucky enough to have one. If the pond is to become permanent try to buy butyl sheeting if you possibly can. It’s the most expensive, but it's going to easily outlast other types and any tears will be easily repaired. Where money is an issue choose a very good quality PVC liner.
If you happen to be building a short lived pond for breeding fish or holding the stock when you’re cleaning out a permanent pond then a cheap polythene sheeting is perfectly satisfactory.
One problem which occasionally arises when buying a Flexible liner is that some suppliers use trade names without stating within the catalogue just which construction material is used. Just be sure you ask before you buy and ensure you check the length on the guarantee.
Rigid Liners:
Having a Rigid liner is perhaps the simplest way of making a small pond . It can be worth considering if you just need a pond for rearing fish, just a little wildlife pond or even a mini-pond for a few aquatic plants and a couple of Goldfish. It’s also a great way of lining a raised pond.
Many experts over the years have warned against using a Rigid liner if you want a well balanced pond for a variety of aquatic plants and several varieties of fish in water which won’t be green with algae. Until quite recently they were generally correct as there was a long list of drawbacks. The cheaper liners had an unacceptably short life and were often luridly coloured. The depths were also generally less than the critical 18 inches and the standard shape was too small and too fussy.
Things have changed quite a bit these days. You will find tough black plastic ponds which includes a long-term guarantee as well as sizes well over 40 sq. ft surface area and depths of a lot more than 18 inches all readily available and simple geometrical shapes are offered alongside the convoluted ones. As well as that they have shelving for Marginals which is a superb improvement. There's even a variety of Rigid liners which have a planting area for Bog plants already built in to them.
When buying your liner ensure that the guarantee runs for at the very least 10 years and choose a dark colour if the construction material is plastic. Make sure the depth is deep enough and keep in mind that a simple shape gives you more surface area for your money than a fussy one.
Concrete Pond:
The traditional type of pond which is still regarded by some as being the best is concrete. Concrete continues to be used where a big square or oblong pond is being built, but that is a job for the professional. But it will be possible to build a simple round or oval pond if you have some experience of working with concrete. Do not forget that if you do try this yourself you do need to complete the job in a single day. When the concrete has dried, paint the surface using a proprietary sealant something like silglaze before filling the pond with water and stocking it. Raw concrete is harmful towards fish.
