Is composite decking suitable for a pool surround? Discover the pros and cons!

What is composite decking?

Composite decking is a material made by combining wood and plastic (WPC – Wood Plastic Composite). This gives it the natural appearance of wood alongside resistance to moisture and mechanical damage. It is available in a range of colours and textures, allowing it to be matched to the style of your garden and pool.

Does composite decking have any disadvantages?

Despite its many advantages, it is worth considering certain limitations:

• Price – composite decking is more expensive than traditional wood, but its durability and lack of need for maintenance mean the investment pays off.
• Susceptibility to heating – on hot days, composite decking can get hotter than wood, so it is worth choosing light colours, which absorb less heat.
• Thermal expansion – the material may change its dimensions slightly in response to temperature, so it is important to ensure correct installation with expansion gaps.

Is composite decking suitable for a pool surround?

Yes, composite decking is ideal for a pool surround. Here’s why:

1. High resistance to moisture and mould

A pool is an area with elevated humidity, which encourages the growth of mould and fungi. Composite decking is resistant to water, preventing it from swelling and rotting as can happen with traditional wood.

2. No splinters – safe for feet

Unlike natural wood, composite decking does not splinter, making it an ideal choice for a pool surround, especially if children use the pool.

3. Non-slip surface

Most composite decking boards have a non-slip texture, increasing users’ safety even when the surface is wet.

4. Easy maintenance

It does not require regular oiling, painting or impregnation. Washing with water and a mild detergent is enough to keep it looking good for years.

5. Durability and resistance to UV radiation

Composite decking does not fade in the sun and is resistant to weather conditions, so it does not need replacing every few years.

6. Attractive appearance and wide choice of designs

Modern composite decking boards look very natural and are available in many colours and textures, making it possible to match them to the style of the pool and garden.

How do you install composite decking around a pool?

1. Choosing the right decking board

Make sure the boards have a non-slip surface and are intended for outdoor use.

2. Preparing the base

A stable structure made from composite or aluminium joists is the best option, as they provide adequate ventilation.

3. Installing the boards

The boards are secured using fixing clips, which ensure the correct spacing and allow the material to expand and contract naturally.

4. Appropriate expansion gaps

It is recommended to leave a gap of at least 5 mm between the boards to prevent them from warping due to temperature changes.

Is composite decking board a good choice for a pool surround?

If durability, appearance and easy maintenance are important to you, composite decking board is an excellent choice. Its resistance to moisture, mould and UV radiation means it will look like new for many years.
