As water places severe loads on the swimming pool structure, waterproofing protection for swimming pools is essential and is an aggressive factor both for its structure and for all materials used in its design. This report deals with the building materials for the swimming pool, and various waterproofing systems and items that could provide protection.
A water-retaining system used for activities such as recreation and exercise is a swimming pool. There are several different kinds, such as a private pool, a public pool, a competitive pool and an infinity pool. Concrete, fibreglass, vinyl-lined pools are used to create swimming pools. Of all these, the cement pool is most widely used. As a freestanding structure or as part of a building like a ship, pools may be sunk into the ground or installed above it. When water spills IN or OUT, ships sink, which means that the pool fails.
By a pre-decided number of procedures, concrete pools are built. This takes several days to a few weeks based on the size of the pool. Thus the, there were few points to note to guarantee the pool is watertight. Essential pool sites, such as building joints, pipe insertions, corners, various fittings such as rails, lamps, and pool surface, shall be adequately handled to render them waterproof.
Water Leaks And How To Waterproof Swimming Pools?
Water leakage is one of the big problems caused by deficiencies in design methods in swimming pools. The correct design, construction measures, waterproofing and tiling system will avoid many structural problems and save money and time as well.
At the time of construction, flaws in the concrete are inevitable. Joints due to delay in construction, due to restriction of the concrete pour, due to dis-similar material employed. These vital positions can be turned water-tight with swellable water-bars. Water-bars based on polymer technology placed on the dry surface of the concrete/any material, and then make the position water-tight if concrete poured. As water at these areas enters, water-bars swell by 3-4 percent in volume and block water flow. At the pipe penetrations, water bars are very useful as they are very easy to mount at the site level. A flexible polyurethane sealant is added to the pipe penetrations after construction at the coating time, seals the junction and serves the water-tightness function.
Construction joints are cut open in the shape of a ‘V’ groove after the pool construction and filled with polymer adapted mortar or SBR admixed mortar. This preparation not only offers the coating with a uniform surface but also ensures less permeable filing of mortar at the joints. Concrete is supposed to have honeycombs and air gaps at intersections, no matter how closely monitored for good workmanship. So, at the time of building, it is highly advised to use a vibrator and do pressure grouting following building.
Significant waterproofing considerations for swimming pools
The hydrostatic pressure of min 2.5 bars must be able to withstand the waterproof device. By adding the best primer / sealer coat before the waterproof sheet membrane, this can be done in the waterproofing membrane. Corners are handled with thermo-plastic-elastomer tapes during waterproofing, since we realise the tension and strains are mostly at the support / junction of the concrete structure the results in the creation of cracks.
The pool is a device that collects water and it requires to be washed at frequent intervals. Thus, the surface of the pool is provided with a system that offers a long-lasting, easy to clean, resistant effect of chemicals, no change in colour, and food grade. Tiles will satisfy these criteria. Using tile adhesive, pools can be built with tiles. The tile adhesive used for the construction of pool tiles must have a high polymer content and pass the strength of the bond in water immersion tests. A minimum of 2-3 mm joints must be preserved at the time of installation of the tiles and grouted with food grade epoxy or polymer-rich cement grout.
With so many choices available, it is wise to discuss a professional to verify that the most appropriate waterproofing solution that is also compliant with the other components in the design of the swimming pool is implemented. For your swimming ventures, engage a waterproofing contractor which has a variety of waterproofing, tiling and concrete repair items.
A prescriptive approach to the configuration of physical properties must be applied before detailed design procedures and requirements are established. Drying shrinkage, elastic modulus, relaxing characteristics, and tensile strength are the most extremely important properties for the provision of robust, crack-free patch repairs.
