Swimming pools are generally opened in outdoor open spaces, and there are also outdoor, indoor and rooftop swimming pools. In the air and on the roof, just avoid water leakage, and the waterproof layer is located on the water surface (in the pool); Outdoor pool, to avoid water leakage and external water, microorganisms into the pool, so to set up waterproof layer inside and outside the pool.
In all kinds of waterproof projects, because swimming pools need to store water for a long time, alternating hot and cold needs to adapt to the change of temperature difference, so the requirements for waterproof materials are higher. There are many kinds of waterproof materials on the market now, which are generally divided into coiled materials and coatings.
The swimming pool is class I waterproof and can store water for a long time. It is recommended to use double waterproof, coated film and coiled material.
The construction speed of coiled material is fast and the waterproof effect is good, but it needs to be cut when paving, especially where there are many detailed nodes, which is easy to leave hidden dangers, so attention should be paid to it during construction.
Waterproof coating is simple in construction, forms a continuous whole after film formation, and has good constructability and waterproof performance for various corners and facades. Therefore, waterproof coatings are more and more respected by construction units.
Paint is a material that can best meet the waterproof requirements of swimming pools. It has super elongation at break, high tensile strength of 6.8Mpa, strong deformation resistance (shrinkage and cracking) of base course, good adhesion, excellent water resistance and corrosion resistance, and is especially suitable for waterproof engineering of long-term soaking parts.
It is necessary to embed 4-5 thick glazed tiles with 4-5 thick polyurethane waterproof mortar, wipe seams with polyurethane building sealant, 15 thick polyurethane waterproof mortar cushion, a layer of non-woven polyester fiber cloth, two-sided polyurethane waterproof coating and 80 thick polystyrene foam plastic board;
Self-adhesive rubber asphalt waterproofing membrane, 20 thick 1: 3 cement mortar, 0.75-0.90kg/m3 polypropylene mixed in the mortar, 20 thick 1: 8 cement expanded perlite slope at the thinnest part, reinforced concrete slab self-waterproofing.
