First, when doing the water avoidance test, there is enough water pressure after water injection. At this time, find the leak point from the outside of the tank and mark it. After the test, you can find the corresponding position on the inner wall of the tank. Before applying waterproof cement mortar, make spot leaks and weak spots on the inside and outside of the pool body. First, gouge and burr the leaky spots and the surface of the weak spots to a depth of about 3-5cm. Clean it up before using it. Plugging King handles it. For crack leakage, you can first cut a 3-5 cm deep V-shaped groove along the crack. For leaking holes, first chisel the holes to a 3-10cm deep funnel shape and clean the surroundings.

If there is honeycomb or loose concrete on the concrete wall surface, it should be kicked off, washed with water, and then smoothed with 1: 3 cement mortar. Then mix the cement and water. At this time, you can add waterproof oil and stir well, and then use a soft brush to apply evenly on the surface of the base layer, and then wipe the bottom waterproof mortar. After finishing the bottom ash, leave it at room temperature for 1 d, and then brush it with cement paste. The mixing ratio and method are the same. After brushing the plain slurry, then you must pay attention to the surface layer immediately. The mixing ratio is the same as that of the bottom layer. The thickness of the plaster is about 5-10mm. Before solidifying, you must use a wooden trowel to smooth it. You can use an iron trowel to flatten it .

After brushing the cement paste, the next step is to apply the surface mortar. After the surface mortar has initially set, brush it again.
