install water and electrical parts. Secondly, as the waterproof subdivisional work is a complex special subdivisional work, the waterproof construction shall be subject to intermediate acceptance, each waterproof practice shall be subject to acceptance, and the water seepage test shall be conducted if conditions permit, so as to ensure the waterproof quality through intermediate control. Do a good job in the acceptance of concealed works in each process, and finally do a 24-hour water seepage test to ensure no leakage before handover. In addition, after the completion and delivery for use, the construction unit shall issue the operation manual to the user, and the user shall not arbitrarily change or damage the decoration of the waterproof structure during use.Conclusion: "three small rooms" waterproof is a complex subdivisional project. Due to the complex causes of leakage, it is indeed difficult to cure the leakage. However, as long as the design is reasonable, the material is properly selected, the quality and process acceptance are strictly controlled during the construction process, and after the completion and delivery for use, the users can use it correctly and maintain it reasonably, the common quality problems of "three small rooms" leakage can be cured.
