What are the hidden projects in home improvement?

Concealed engineering refers to the pipeline engineering and structural engineering hidden inside the decorative surface, which is particularly important because it involves the safety of water and electricity and is inconvenient to maintain.

Water supply and drainage works

The most important concealed works are water supply and drainage, circuit and waterproof works. Water supply and drainage is the most common concealed work, including water supply installation and drainage installation, and all upper and lower pipes should be kept unobstructed.

It should be noted that if you want to change the waterway pipeline, you must say hello to the property and ask professionals to design the pipeline direction for construction to ensure that the main waterway does not move in principle.

Circuit engineering:

Circuit installation requires high material quality and construction technology. Before decorating and wiring, the circuit should be designed comprehensively, and the pipeline laying should be carried out in strict accordance with the operating specifications to avoid the occurrence of power safety accidents.

Waterproof works:

The original waterproof layer of kitchen and bathroom is easy to be damaged due to pipeline reconstruction. If the waterproof treatment is not good, leakage will occur. Therefore, after the waterway reconstruction is completed, it is best to be waterproof at once. Before wall construction, we must do a 24-hour closed water test.

In addition, some projects that can't be seen from the outside after completion, such as keel laying of floors and ceilings, and grass-roots treatment of walls and door and window covers, are also called concealed projects. So we have to wait for water, electricity and carpentry to finish these projects and pass the acceptance before we can carry out the next renovation.
