Stages of construction and installation of swimming pools

1. Determine the location location of the pool

To install a fiberglass pool, be correctly select location, since it affects their design features and the degree of convenience, adoption of water treatments.

Planning permission for a swimming pool It must be located on the sunny side, It is protected from dust and leaves. Tall trees and shrubs, located next to the pool with their fallen leaves pollute water, and the root system can deform the cup. Do not install the pool on the bulk, floating or fertile soils. Soil type is determined by drilling boreholes or digging pits. errors, admitted at determining the bearing capacity of foundation, can lead to misalignment of the cup and its deformation.

Attention: before installing the pool on the site, consult a specialist in the construction of. In special cases,, when there is instability in the soil, special primer, slope, and other non-standard situations which require further strengthening of soil or the pool, these decisions are made by a specialist in the construction of.

Ground water level, which should be below the pool bottom plate at least 20 See also one of the main conditions when choosing a place for the pool. If, nevertheless, the groundwater is high or the likelihood of their occurrence (if the soil is clay based – ground water may rise due to heavy rainfall) it is necessary to equip a forced drainage system around the base of the pool. The drainage system protects the pool body from possible deformations, arising from the movement of groundwater around the pool. Groundwater also affects pool water temperature – heat is being extracted. If there is no natural drainage on the site, be sure to equip the pump. Lowest part of drainage systems, should be below the bottom of the pool

Before starting the installation of the pool bowl and installation of equipment, the Customer must perform the following work:

  1. Water supply to the sump with the installation of a shut-off valve Ø 25 mm. (1 inch)
  2. Connecting a single-phase electrical power supply with a PVA cable with a section of 3x4 with standard equipment and a three-phase electrical power supply with PVA 4x6 when selecting additional equipment;
  3. Sewerage connection in a pit Ø 50mm;
  4. Ground loop in the pit;
  5. When installing equipment in a basement, a hole remains in the outer wall of the building 300 x 400 mm at mark -1,0 m from the water mirror in the pool.

The list of additional equipment is agreed at the stage of drawing up a commercial proposal, taking into account recommendations for the installation of technological equipment.

2. Pit marking

After defining the species, dimensions of the pool and sump for technological equipment the pit is marked under the bowl pool and pit with some margin: pool pit 300 mm perimeter and pit 150 mm around the perimeter according to construction drawings. When excavating, the walls and bottom are carefully leveled, removing all the remnants of loose soil. After that, like a dug pit, the land is taken out or covered with low-lying areas of the territory. When developing a pit, you need to take all measures, so that the soil does not crumble from the walls of the pit. If the depth of the pit exceeds 1 m, then its walls should be made with a slope towards the outside, so that the soil does not crumble to the bottom. The pit for the pit must be dug on 200-300 mm (depending on the size of the pit) above the base of the pool pit. At the bottom of the pit, a layer of sand and gravel is laid on 8-10 cm and pour a concrete slab under the pool bowl 150-200 mm. Are released from the concrete slab pool anchor and pit. The concrete base of the slab must be leveled with a cement screed strictly horizontally under the planned zero level of the pool bowl, taking into account the insulation density 35-40 kg / cm² thick 20 mm. Ground loop, subsea pipelines, lead the electric cables in a protective sheath into the pit. The pool bowl is placed on a sufficiently solid concrete base, but not earlier than in 72 hours after the manufacture of cement screed at positive temperature.

3. Installing the pool bowl

After installing the pool bowl installation of fittings, pipelines, people. cables, equipment pit. The bowl is filled with water 300-450 mm, fastened to the hinges of the pool and the pit to the anchors with wire and pidmured. The bowl is fixed at the corners of the pit. In the event that there are two depth steps in the bowl, then, first of all, the corners in the part of the bowl of greater depth are filled in with a brick to avoid subsidence.

4. Installation of equipment

Installation of technological equipment carried out at the individual request of the Customer. An important factor, which ensures the preservation and full functioning of the equipment, is placing it in a special pit. The pit installation location is determined at the stage of marking the pool perimeter. The distance from the pool to the sump should not exceed 3 m, as there will be a need to use more powerful and expensive equipment. The cushion for the pit consists of a sand-pounding mixture h – 150mm with fixing the pit to the anchors for the hinges and stiffeners and installing spacers inside the pit to avoid compression.

The pool should be backfilled with a damp mixture of m 150-200 thick 300 mm along the perimeter with a gradual selection of water above 150 mm of gartsovtsi, with seal, at the same time it is necessary to make sure, that the hartsovki gets into all the cracks and under the steps.

Between the walls of the foundation pit and the groove is the formwork made of foam plastic with a density 15-25 kg / cm ² (10 x 0,5 x 0,05) on distance 300 mm from the sides of the pool. The foam serves as thermal insulation between the soil and the pool, which significantly reduces the cost of heating water. The rest of the voids are filled with sand. If a hole is dug around the pool, larger in size, than indicated in this manual, a retaining wall is being built to avoid soil pressure on the pool bowl.

To install a cover and relaxation area around the pool and the pit is made of a concrete slab with reinforcement, thickness 150-200mm. Reinforcement rods should not be closer, than on 100 mm from the surface of the slab. The size of the slab is determined in accordance with the selected pavilion or the desired size of the beach area (width at the edges of the pool about 90 cm with a slope from the pool) and faced with tiles or other materials.
