Liner swimming pools are made up of a framework or shell constructed of various materials available, including; galvanised steel or polymer panel s. It is then lined with a PVC membrane (called the liner) which gives the pool its water retaining properties. The liner pool with its many different colours and patterns including mock tiling or mosaic with its high standard of construction and finish is a cost effective method of owning an installed pool and many people cannot tell the difference between a liner and tiled pool!

Whereas a concrete swimming pool, using the traditional way to construct a pool, can be divided into four different categories; reinforced blockwork, unreinforced blockwork, sprayed concrete and shuttered concrete. Instead of fitting the swimming pool with a frame the swimming pool has a concrete and sand shell, which is ready to be tiled over and made waterproof.

Having a panel and liner swimming pool can be incredibly advantageous for people who like to have a bit of leisure in their lives. When your swimming pool is installed with a liner, it becomes virtually maintenance free and you can also choose across a variety of colours and patterns for your liner.

We at Cascade Pools have been installing panel and liner pools for over 40yrs and believe they are well suited to the heavy clay ground conditions in this area offering a degree of flexibility within the structure against any potential ground movement damage to the pool shell unlike concrete tiled pools which could crack under certain diverse weather conditions and cause a real problem for the owner.

To get an idea for the size of pool that will suit your garden and requirements, it is advised to chalk the outline and measure, it will also give you a visual idea. However, bear in mind that you will need to allow space for the paving that goes around the perimeter of the pool. To get a rough idea of what size pool you would like, the average family sized outdoor swimming pool is around 10m x 5m (approx 32 feet x 16 feet) and an indoor pool is approx. 8m x 4m (28 feet x 14 feet).

It is very important to know the capacity of your swimming pool to enable the correct water balance to be maintained by adding the correct quantities of chemicals required to the water.
Below is a quick formula to help you find out:

• For circular pools:

Imperial : Diameter (ft) x Diameter (ft) x Average Depth (ft) x 4.9 = Gallons

Metric: Diameter (m) x Diameter (m) x Average Depth (m) x 0.8 = Cubic Metres.

• For rectangle or square pools:

Imperial : Length(ft) x Width (ft) x Average Depth (ft) x 6.25 = Gallons

Metric: Length (m) x Width (m) x Average Depth (m) = Cubic Metres.

• For oval pools:

Imperial : Long Diameter (ft) x Short Diameter (ft) x Average Depth (ft) x 5 = Gallons

Metric: Long Diameter (m) x Short Diameter (m) x Average Depth (m) x 0.9 = Cubic Metres.

When you start your pool project with Cascade we ensure you and all workers share the same information, so you are never left in the dark. All relevant information regarding the different aspects of the pool installation is available to the customer initially and throughout the installation.

Swimming pools can be heated by a selection of energy resources including gas, electricity, oil, ground and air source heat pumps, solar, wood pellet burners and even wind turbines. However, renewable energy is only suitable for outdoor pools, as indoor pools require dehumidification and a sophisticated range of systems.

One of the most popular heating systems for swimming pools is the heat pump, as it is effective and economical (should cost approx. £2.00 per day to heat depending on the size of the pool).

We recommend you take advice from a suitably qualified electrician or heating engineer for technical questions relating to your existing household electrical supply or capacity of existing gas or oil boilers to enable us to assess if your current services are sufficient to support your preferred heating choice for the pool.

Particular covers can also be used to help with the safety of the swimming pool for instance, preventing children accidently falling into the pool. There are also a variety of pool covers available including manual, semi-automatic and automatic systems.

If you have an irregular shaped swimming pool it is important to find a cover that can be custom fit to the shape of your pool.

A liner pool can take on average 3-4 weeks to install. However, paving and other extras can prolong the completion of the build. The length of time it takes for a pool to be completed usually depends on a range of variables such as, weather conditions, ground conditions, size of pool being installed and sometimes suppliers. The accessories; depending on the accessories you have chosen for your swimming pool or the amount of accessories you want installed can also alter the original time frame given.

Having steps or ladders incorporated into the build is an essential to your everyday swimming needs as they allow fast and easy access out of the pool without running the risk of hurting yourself when trying to lift yourself out of the pool. They are also essential for the health and safety of the pool.

There are a wide variety of steps to choose from including; stainless steel ladders which drop in over the side of the pool or Walk-In Stairways, including square, roman (half moon) or corners. For indoor pools internal corner or roman steps are ideal as it won't take up any room around the pool. With outdoor pools you have more choice with the design and style of the steps.

It is predicted that a liner should last for approx. 7 to 10 years; however there are liners that are more robust and can last for about 10 to 20 years. There are different grades of liners, with different life expectancies, for example the standard 20thou (0.5mm) and 30thou (0.75mm) liners carry a 5yr pro rata warranty but usually last for around 10 years, whereas the much thicker 60thou (1.50mm) liner has a pro rata warranty of 10 and could last for around 20yrs. (this all depends on the after care of the liner by the customer)

To guarantee a longer life for all pool liners, it is recommended to keep the swimming pool well maintained using the correct pool chemicals and keeping the water temperature within the recommended limits

The most effective and cost efficient to heat a swimming pool is by heat pump.

Pool insulation is another way of maintaining the heat within the pool and has the potential savings of up to 90% of the running costs when operational. New build pools can have the insulation incorporated at the build stage or existing liner or concrete/tiled pool shells can be insulated when the pool is being refurbished.
