Waterproofing construction of water pool
Release time:
Dec 05,2023
There are many types of water pools for classification, such as drinking and living water pools, elevator shafts, fire water pools, backup water pools, swimming pools, sewage treatment water pools, etc., which use cement structures to hold water in different sizes and shapes.
1. Cement based permeable crystalline waterproof coating
Its waterproof layer belongs to the green and environmentally friendly type, which can be used for waterproofing treatment of various types of water pools such as fish ponds, water tanks, swimming pools, etc; The waterproof layer is highly acid and alkali resistant and can be used for waterproofing in general domestic sewage treatment tanks without the need for anti-corrosion; The long-term soaking performance of the waterproof layer is very good When soaked in water for a long time, the waterproof layer does not fall off or peel off. It has good impermeability and compression resistance, and can be used for waterproof and moisture-proof treatment of large water tanks. When the water content is over several thousand tons, the main body of the building usually does not deform, and the waterproof performance does not change. The waterproof layer has good adhesion with concrete, and does not fall off or peel off. After waterproofing, it will not affect the plastering or tiling process. 2. Rigid waterproof dry mortar
Rigid waterproof dry mortar is made by fully mixing specially made cement and various active chemical substances. Its special ingredients make it permeable inside the concrete and form crystals with water to seal internal cracks and pores, increase the compactness of the concrete, and achieve complete waterproofing. Therefore, post construction maintenance is very important, and it is necessary to spray clean water on the surface of the waterproof layer 1-2 times a day for a week before conducting a closed water test. Its outstanding advantage is that even if the waterproof coating layer is damaged, it will not affect the waterproof effect. The most suitable waterproof construction for reservoirs is the best choice for reservoir waterproofing.
Waterproof construction requirements
1. Review the drawings before construction and prepare a waterproof engineering construction plan for me. Operators of underground waterproofing projects must hold a certificate to work.
2. The base layer of the waterproof layer must be constructed according to the design and dried after curing, with a moisture content not exceeding 9%; The base layer should be flat, firm, and free from hollowing, cracking, and large sand.
3. Before applying the primer for the waterproof layer construction, the surface of the base layer should be cleaned thoroughly.
4. All construction materials are flammable, therefore corresponding fire-fighting equipment should be prepared.
5. The pipes embedded in the waterproof layer of the underground membrane shall not be damaged or blocked with debris during construction.
6. After the waterproofing layer of the roll material is laid, a protective layer should be promptly applied to prevent damage to the waterproofing layer during structural construction; After the construction of the external waterproof layer is completed, the protective wall should be built according to the design.
7. During the construction of the roll up waterproof layer, materials shall not be placed on the waterproof layer or used as a construction transportation lane.
8. Construction process: base cleaning, applying base treatment agent, laying additional layer, laying roll material, and hot melt edge sealing.
