Introduction

A swimming pool is a water-retaining structure that can be used for leisure or exercise. You can either sink a pool into the ground or build it above it.

There are many types of pools, including:

Private pool

They can be built in a yard, inside a house or into a basement. They come in a variety of sizes, but the average size is 3.7 MX 7.3mx 12.2m.

Public Pool

Most public pools are rectangular and 25-50m long. You can have them in any shape or size.

They must comply with the standards established by FINA, The International Swimming Federation. These require that pools be at least 25 m in length, at least 1.35m deep and at least 8- lanes broad. To meet heating and lighting requirements, these pools are usually indoors. They may include starting blocks, electronic timing, results from screens and warm-up and cool-down areas.

Infinity pool

Infinity pools are often found in luxury resorts and hotel settings. They feature water flowing over a few edges, creating the illusion of merging with the sky or ocean. The weir is built just below the pool edge. The weir collects water that spills over to the weir and is pumped back into the pool.

Construction methods

To meet the British Standard 8077:1987 water-tightness requirements, pools must be designed and installed. This says: “During the 7-day test period, the total allowed drop in water level should not exceed 1/500th the average water depth of a full tank, 10mm or any other specified amount.”

Although pool design is different from construction, they all rely on similar plumbing filters systems.

Filtration

There are many filtration system options, including:

Diatomaceous (DE).

These use mined fossilized exoskeletons made of tiny diatoms that act like tiny sieves to remove any debris. Although they can filter particles as small as 5 microns and are more expensive, they require more maintenance. 

Sand

Water flows through a layer of filter Sand before being pushed to the bottom by a series of lateral tubes. The pressure on the filter sand will increase as the pool becomes clogged with debris. At this point, the water flow will drop, and the filter must be replaced.

Cartridge

Water is passed through a filter substance that captures the debris.

Method for construction

The primary difference between the pool types is how they are constructed for the basin ‘.

Above-Ground Pools

These are the easiest to build and most often assembled using prefabricated kits. However, there are safety issues because it can be hard to see the pool from the surrounding area.

Fiberglass Pools

Fiberglass-reinforced plastic can be molded into a basin shape to the required specifications. The hole is dug, the plumbing is laid, and then the pool is lowered into it. Sand filler is used to create the desired shape. A concrete deck structure is usually built around the perimeter of the pool to protect it.

Vinyl-lined swimming pools 

The hole is dug, and a timber, metal or plastic frame wall is built around it. Sand Filler is laid in the hole. A vinyl lining is then attached to the perimeter wall. These are generally less expensive than other in-ground designs. However, they are more durable because the liner needs to be replaced approximately every ten years.

Gunite pools

After a hole is excavated, the plumbing has been placed in. The framework grid is then laid off a bar. The heavy coating is applied to the surface. This is done with a mix of cement, sand. The mixture is then trowelled and allowed to dry. You can finish the pool with plaster, concrete paint or tile.

Concrete pools

These are similar to gunite pools, except that concrete can be poured into conventional timber formwork. Another alternative is to build walls with concrete blocks. As gunite techniques have improved, these are less common.

Other items that could be included in pool construction are:

  • Recessed rest ledges
  • Overflow Channels.
  • Start platform upstands.
  • Ladders – Types include those that are recessed in the pool tank or tiled and face-fixed stainless Steel. 

Tiles

When tiles are placed in swimming pools on renders or screeds, the mortars used to level them should be dried and allowed to dry. Tiles should have a minimum water absorption of 3% and sufficient slip resistance to be used in their intended location.

The adhesive and grout used to grout tiles must be resistant to chemicals and pool water. Otherwise, their durability could be compromised. The factors that determine the type of glue and grout that should be used are:

  • Type of tile.
  • The mains water Quality.
  • Chemicals are used to treat pool water and maintain the pool.
  • The location for tiling and the design pool

Two main types of pool sealant are used to plug holes.

  • Epoxy-based sealants.
  • Unplasticized polysulphide sealants.

Lines

The design can include warning lines, pool guidelines, and demarcation lines in the tile layout. The most common colors are white, blue, and black. Dark tiles shouldn’t be used as a pool base because they can make it hard to see the depth of the water. For lane and depth markers, special screen-printed tiles are available.

Stainless Steel

Stainless Steel offers a broad and valuable service for industry, leisure, and other sectors. This is due to its properties. Its resistance to color and appearance are the most popular characteristics. It also has other advantages, such as lower susceptibility to bacteriological resistance, improved fire resistance, and better flexibility than carbon steels.

These attributes are important, but it is also crucial to choose the right grade of stainless steel. Stress corrosion could occur in swimming pool environments. This is especially important if the use of structural is being made or if failure could cause damage or harm. This category could include items that are not normally considered structural.

High temperatures, high numbers of users and chemical disinfectants can all lead to very dangerous situations in swimming pool construction environments. Stress corrosion cracking can occur in a particular combination of the following conditions.

  • The component has high levels of applied stress due to applied load or residual stresses from welding/forming the component.
  • Susceptible grades steel.
  • Environment.

Stress corrosion cracking refers only to elements within the pool atmosphere and not those fully submerged in the pool waters.
