Swimming Pond Construction

Our approach to design and construction ensures a unique project, built to our exacting standards, which will provide years of enjoyment and fun, while also making a significant contribution to the environment.

The construction phase begins with the dimensions of the swimming pond and associated hard and soft landscaping elements being set out on the ground, according to the set out plans derived from the design plan.

If access permits, the main excavation is usually carried out by a 13 tonne tracked excavator with the support of a smaller tracked machine. Topsoil is separated from subsoil and is usually landscaped into the surrounding area. If this is not possible, the spoil can be removed from site.

Once the excavation has taken place and the shape, depth and profile of the pool determined, a protective membrane is installed. An artificial liner is then laid onto the membrane to completely line the swimming pond. An additional protective membrane is then laid onto the liner.

A reinforced concrete base forms the floor of the swimming area. A suitable colour can be added to the concrete during mixing to create different effects.

A swimming pond is essentially made up of two main components, the swimming area and the regeneration zone and these 2 areas are separated by an internal wall that can be made from a variety of materials. These might include timber, clay bricks, stone or in the case of the example shown, a smooth faced block. The wall terminates 20cm beneath the surface of the water and usually has a top course of bull nosed engineering bricks, which work very well when creating curvaceous walls. If the walls are straight then a timber capping may be used instead.

A 1m deep biological filter is created between the outside of the internal wall and the perimeter of the swimming pond with a combination of stone and filter medium.

A series of perforated pipes are installed through the lower part of the filter (regeneration zone) and are connected to an external pumping chamber.

A skimmer is positioned to receive the prevailing wind and connected to a second pumping chamber. The skimmer removes any surface debris from the water, such as fallen leaves.

To prevent nutrient rich ground water entering the system an inception drain is installed around the perimeter of the swimming pond. An overflow facility is positioned to control water level.

Access to and from the water can be in the form of traditional ladder steps or brick/block steps. Timber decks and jetties can be built to create transition to the water and beautifully compliment swimming ponds.

Once the pond has been filled, the final stage is to introduce the aquatic plants to the regeneration zone. The plants will in turn soften all the edges and optimize the aesthetic value of the swimming pond in a very short period of time.

Lilies and oxygenating plants are planted into deeper areas within the regeneration zone and play a major role in keeping the water clear.
