The right material

At LD-Pools we only use the best quality materials for our products, but because there are so many materials available for pool and spa construction, we have established an overview of some of the more common types used.

1. Stainless Steel

The initial high costs of stainless steel are justified by its durable composition.  It´s a very popular material for it´s long-lasting qualities. There are some characteristics of this material that must be considered, including:

- A tendency to rust at welding points, incisions or sections that overlap. This underlines the importance of thorough production and manufacturing techniques.

- A rusty surface which can develop if the water is not treated properly. This can occur despite flawless production.

- A susceptibility to over-chlorinated water that can cause damage to its surface and hinder its functionality.

- Potential ´blistering´ due to excessive sun exposure. This means that adequate thicknesses should be used with accurate strengthening.

- Inflexibility and robustness mean modifications with stainless steel can be problematic.

2. Polypropylene

Polypropylene, also referred to as PP, is a strong, acid and alkali-resistant resistant plastic. It is commonly used in industry pipework, since it is durable, easy to weld, and can be manipulated to various shapes and sizes without difficulty.Polypropylene is imbued 100% and is UV resistant, available in many colours, and its smooth surface means that it is easy to clean.

To ensure strength, PP swimming pools are welded on both sides with a static reinforcement, such as steel pipe framing. These frames should be coated with polypropylene plates in order to make them corrosion-resistant. The wall thickness should not fall below 8 mm.

Heat strain is a possibility with polypropylene pools. PP pools are especially susceptible when they are empty and exposed to sunlight. Ripples can form on the pool walls, however, if the steel pipe frame has been installed correctly this is usually minimal, and can be treated by simply filling the pool with water.

Like all pools, the manufacturing process of polypropylene pool is very important. Correct welding techniques should be used, in addition to solid reinforcement. Attention to detail will ensure the longevity of your pool.

3. Polyester

Polyester pools can be shaped to form smooth curves and angles, and are also popular due to there simple construction and easy maintenance. Polyester pools retain pool water with a firm glass-like surface, that is relatively cheap when compared to other pool materials.

However, polyester does have its disadvantages. Polyester can lose its colour from UV rays and chlorine, and when you heat a polyester pool it discolours rapidly. Over time, water can penetrate the materials surface, and in cold temperatures this water can freeze and force the polyester surface to crack. Much attention must be paid to water treatment water temperature.

4. Sheet Linings

Sheet lining refers to any pool with a sheeted surface that is glued and/or welded onto the pool base, and typically consists of framework and a sand or cement base. Sheet lined pools are popular, because the price is very competitive and because many colours and patterns can be achieved. Other benefits include easy maintenance.

Much like polyester pools, much attention needs to be paid to water treatment and water temperature. Pipe fairleads and fastenings that lead through the sheet lining can be susceptible to leakage, so comprehensive sealing methods are vital. Other considerations for sheet lined pools include folds, which can occur in the surface if the pool lining is not properly installed, or if water conditions are not maintained.
