To construct a pool, it is first necessary to prepare the appropriate location and required conditions, and then proceed with the execution of operations. The stages of pool construction and waterproofing are as follows:
- Excavation and Debris Removal:
The swimming pool site is excavated using appropriate machinery and tools. After excavation, the debris generated is removed from the site by debris removal vehicles. - Application of Cement Rendering:
Following the excavation and debris removal, cement rendering is applied to the pool walls and the concrete base to prepare the structural foundation and facilitate rebar installation and concrete pouring. - Rebar Installation:
Before concrete pouring, the surface must be prepared by installing rebar. Typically, rebar installation for the pool formwork is done using No. 16 deformed bars in two rows, spaced 25 cm apart. - Concrete Pouring for Floor and Walls:
Once the pool is formworked, it is ready for concrete pouring. The average thickness for the walls and floor of the pool is between 25 to 30 cm, using a cement grade of 350. It is recommended to use N50 concrete adhesive and additives for concrete pouring to enhance water resistance and strength. Additionally, WS30 waterstop strips can be used at concrete joints. - Insulation:
The best time for insulation is after completing the concrete pouring. First, the concrete surface is smoothed using B70 mortar adhesive and additives to prepare the base for the main insulation layer and repair any defects in the concrete. Then, the entire pool surface is waterproofed using Z90 resin and sealing adhesive (following method 222). - Tiling:
It is recommended that tiling also be done using B70 mortar adhesive and additives.
Note: The installation of mechanical systems and the provision of inlet and outlet pipes are carried out before concrete pouring.
