Construction of concrete swimming pools

Construction of concrete pools

Traditional pools are made in the form of a concrete basin lined with glass mosaic or high-quality swimming pool foil. Construction of a pool in this technology gives full freedom as to the shape, size, depth or location of the basin. This solution, thanks to its solid construction, is very durable and is gladly chosen by customers for the construction of a year-round indoor pool. Also, the finishing elements do not limit the investor in any way, so that any vision/design of the architect can be realized.

The freedom of shaping the pool basin and installing virtually any water attraction including built-in massage seats or bypassing the pool in the form of a "rushing river". Any shape, design, idea in the case of a concrete pool is realizable, and the range of possibilities for additional equipment is incomparable in comparison with, for example, prefabricated pools.

Types of concrete basins

  • reinforced concrete basin - this is the optimal solution, providing a coherent whole for the entire basin. The solution is quite expensive, requiring a lot of work, however, very durable, reducing to a minimum the problem of leakage of the basin.
  • concrete block basin - a far more economical solution, consisting in the construction of a basin of dedicated concrete blocks. The structure is definitely weaker than the reinforced concrete one, however, additional reinforcements in the form of retaining columns and a concrete rim, strengthen the entire structure.

Pool version

Skimmer Pool

The water level is kept below the edge of the pool by about 8 cm. This is the most classic and well-known solution. The principle of operation is simple - water flowing into the skimmer is sucked by the circulation pump and pumped through the pool filter, which collects all the impurities, towards the pool inflow nozzles. The next step is to heat the water, using a heat exchanger, electric heater or heat pump. After the filter, the pH is corrected and chlorine is dosed, via peristaltic dosing pumps. At the stage of construction/delivery of the pool, do not forget about the bottom drain, which will facilitate its use. It is also worth considering the installation of attractions such as counter-current, spout, air massage, which will increase its recreational value.

Overflow Pool

The water overflows from the entire surface of the mirror into an overflow gutter and then into an overflow tank, where the level is regulated automatically. The rest of the pool technology is identical to that of a skimmer pool. If you choose this type of overflow form, you need to pay great attention to the preparation of the ground and the pouring of the foundation, because this type of pool does not forgive construction errors. A pool with an overflow gutter creates unity with the surroundings, and is an extremely decorative and design element, intended for the most demanding customers.

Finishing form of concrete basin

Ezzari glass pool mosaic

Concrete pools are most often lined with Spanish Ezzari glass mosaic, which, with the use of a properly prepared surface (leveling, insulation, glue, grout), guarantees a pleasant visual effect and high resistance to mechanical damage.

The technology, refined over the years, has brought the final product to perfection: it does not fade, does not wear, does not crack, and most importantly, it serves for many years, without losing its beautiful appearance and deep color. It is possible to fully personalize through your own graphics, which can be placed on the mosaic.

Glass mosaic, in addition to its visual appeal, does not react with pool chemicals and is resistant to UV radiation (a big advantage for outdoor pools).

Renolit Alkorplan pool membrane

The Alkorplan 2000, 3000, Touch pool membrane was developed as an alternative to mosaic/tiled pools. The membranes are suitable for any pool shape, size and form. The material is suitable for lining indoor, outdoor, public and private pools, new and for renovation. The rich color palette will satisfy the needs of even the most demanding customer and allow you to create a unique pool. After the construction of the basin, the installation of the film (foiling) consists in lining the entire interior of the pool with ALKORPLAN liner, prior attachment of PVC-coated angles to the edges of the pool and hot air welding of the film to the fastening elements.

Stages of concrete basin construction

Due to the diversity of the locations of the projects, the stages may differ.

For example, there will be a different construction technology for a pool located in a slope, and another for one embedded in the ground. An overflow trough pool is built differently, and a skimmer pool is built differently.

  1. Excavation and construction of gravel bedding and reinforcement mesh on the bottom
  2. Embedding elements/passages located in the bottom of the pool (e.g. bottom drain, inflow nozzles)
  3. Making reinforcement of the pool walls or masonry them with concrete blocks supported by reinforcement columns
  4. Embedding pool technology elements in the pool walls (i.e., lamp niches, masonry penetrations of inflow nozzles, masonry penetrations of nozzles and attraction intakes, etc.).
  5. In the case of a reinforced concrete basin, the reinforcement is poured with concrete of the appropriate class.
  6. Implementation of PVC installation around the pool, including the transition to the technical room
  7. Insulation and insulation of the basin from the outside
  8. Preparation of the inner part of the pool basin, i.e. its leveling
  9. Lining the pool with swimming pool foil or mosaic
  10. Installation of technological elements inside the basin, i.e. nozzles, blends, lamps, etc.

As you can see, the process is quite complicated and requires good organization and alignment of the technology industry, with the construction industry. In addition, it is important to have precision workmanship and experience to eliminate errors that may occur.

In addition, you should know that:

  • In addition to the pool itself, there will be a need for a technical room that houses the complete technology. The ideal solution is when the bottom of the technical room is below the bottom of the pool basin, but ze is not an absolute requirement. Let's remember that we will have to go into this room for inspection purposes and ongoing maintenance - rinsing the pool filter, dosing pool chemicals, so it is worth taking care of easy access.
  • If we choose an overflow pool, we will need an overflow tank into which water from the overflow trough will flow.
  • In place of the technical room will need power supply and sewerage. In addition, if the pool was to be heated from the central heating furnace also needs to "find" the heating medium there.
