Setting up a Garden Pond

A garden pond is a water feature that enhances the appearance of a garden and supports a wide range of plants and wildlife. There are endless variations when installing a garden pond dependent on the objectives of the project. All this is determined by what you intend to keep and the purpose of the pond. For example it can be based around ornamental fish, aesthetics to coincide with the design of your garden, a wildlife pond etc...

 

Wildlife ponds are generally shallow, around 45cm (18inch) to encourage specific creatures into the feature. Not all wildlife ponds require a pump and filter as specific plants can be used to purify the water, although filters will help to improve clarity.

 

A Garden pond has no or little requirements with regards to size and shape of the pond, however a general garden pond will almost certainly require a -

pump and filter to help maintain water quality. If you want a waterfall or fountain then a pump is essential.

 

Koi pond is a specific feature with one purpose, keeping and displaying Koi carp. Koi are notoriously messy creatures that excrete vast amounts of waste into the pond. Because of this an air pump and suitable filtration system are a must. It is also often the case that in order to keep a crystal clear pond, plants should be avoided or protected as Koi have a tendency to root through the soil causing constantly murky water. Koi ponds need to be much deeper at least 90cm (36inch) in order to help sustain temperature during the colder winter months.

 

There are three main types of pond installation to choose from liner, pre-formed and concrete.

 

 

Liner installations require a degree of preparation in order to produce a nice shaped pond. By using liner you can completely tailor the shape and dimensions of the pond to your own specifications. Liner is often the cheapest way to produce a pond and is available in various qualities, the majority of which hold a 30 year guarantee.

 

The formula for calculating the size of the liner is as follows
(maximum length + 2x maximum depth) x (maximum width + 2x maximum depth) = required liner volume i.e. maximum depth is 2ft so that becomes 4ft, length is 6ft and width is 8ft = 10ft x 12ft

 

When calculating the area of liner you should always allow a little extra in the measurement of length and width to account for any required overlap for ledges and the side of the pond.

Preformed Pond


Pre-Formed Ponds are produced for ease of instillation having already been sculpted into a desired shape, saving time and effort of designing and arranging soil to produce a nice shape pond without any creases or folds. The majority of pre-formed ponds are a rigid self supporting structure that can be inserted into a framework and backfilled with soil, hence no digging wholes. Pre-formed ponds are available from 15 - 4500 litres in epoxy resin and fibreglass. Guarantees are between 15 years and 30 Years

Concrete Pond in Construction


Concrete ponds are often built in a traditional box shape and are produced from breezeblock or brick and sealed in concrete or cement. It is imperative that these ponds are sealed with a finishing coat to waterproof the surface and protect the pond water from chemicals in the brick, concrete or cement and to seal the pond and stop water from seeping through.
