My family built a pool, but one side of it cracked because of the drought. Excuse me, master, how to repair the pool before it can be used again, so as not to leak.

? Due to the complex structure of the main building of Shenzhen Metro, the waterproof requirements are extremely strict. The leaders of this property project attached great importance to it, and specially found seven or eight well-known waterproof enterprises for comparison, and made simulated closed water tests on the spot.

? The test method is as follows: a pool is temporarily built with light bricks on the simulated settlement joint, and waterproof paint is directly painted on the inner wall of the pool after the mortar is approved. A few hours later, the test pools of other waterproof coating manufacturers began to soak, and some showed water marks. The pool coated with Qinglong Water Curing Glue (CQ 10 1 waterproof sealing coating) does not leak after being filled with water, and the external wall is as dry as ever. Check again in a few months. Due to the pressure of water and the sinking tension of the settlement joint, the pool cracked a hole about 4 cm wide, and the sudden accident made the people at the scene sweat. /kloc-after 0/0 hour, there is no trace of water on the outer wall of the pool.
