What are the water leakage situations in pools:
1. Large-area water seepage. Large-area water seepage generally occurs in the floor. The main reason is that the precipitation in the foundation pit around the base surface should be below the cushion layer. Because it cannot reach the appropriate level, it causes poor drainage and the water level in the foundation pit rises, submerging the cushion layer. The conditions for pouring concrete are available, but at this time, in order to achieve a certain project progress, construction with water was carried out.
2. Water seepage form of construction joints. Because during construction, people are used to artificially dividing the entire ground into many blocks. During construction, construction will be carried out according to several blocks instead of overall construction, so this leads to problems after the construction is completed. Gaps appear.
3. Water seepage form of deformation joints. Because the waterstop is not firmly fixed and the concrete is not pounded tightly and solidly, the whole thing will deviate from the center, resulting in pitted holes on the surface of the object. After water erosion, this situation will become worse and worse. serious.
4. Water seepage form of wall-penetrating pipes. There are also various pipes in underwater projects, such as air ducts, water pipes, electrical pipes, etc. The connection with the main pipe is not tight, and the welding joints are defective. When the concrete is poured, it may cause cavities. If there are holes in the space, it will lead to water seepage.
How to deal with pool leakage:
(1) Surface repair method. It is mainly suitable for long and slender seams. It is commonly used to lay thin film materials along the surface of the same crack, such as epoxy resin or resin-impregnated glass cloth. For clean water pools, non-toxic, non-polluting and environmentally friendly materials must be used, and the appropriate one should be selected according to the reference requirements. material.
(2) Filling method. When the crack is wide, a V-shaped or U-shaped groove can be created along the surface of the cracked concrete and filled with resin mortar materials. Materials such as impermeable mortar or asphalt can also be used, and the surface can be strengthened using the above methods. It is also necessary to wait 7 days after the treatment is completed before subsequent construction can be carried out to avoid failure of the filling material.
(3)Injection method. When the crack width is small and deep, the repair method of injecting the repair material into the concrete can be used. First, an injection pipe is installed at the crack, and then the surface treatment method is used to seal it.
