Usually, water and electricity are done first, and waterproofing is only done after the water and electricity are completed. This is mainly because these two projects belong to different projects, which are carried out in the following order: after the house starts construction, the first thing to do is the interior decoration. After completion, the interior walls need to be removed, and the garbage inside needs to be cleaned up. After the walls are removed, one can decide whether to build the walls according to their own requirements. At this time, yellow walls, greening, on-site measurement, direct construction completion, and pressure testing of water pipes are carried out, and preliminary slotting of water and electricity is carried out, such as central air conditioning; Mud workers enter the site to build walls, package drainage pipes, and perform miscellaneous tasks such as wall and floor construction; Waterproofing has begun to enter the site, and the bathroom wall section should be constructed first; The bricklayers begin to lay the wall tiles, such as in the bathroom where "wall pressing" is carried out as needed until the wall tiles are laid;

After completing the water and electricity work, fill the gap between the ground and the pipeline first, and then carry out waterproofing. After the waterproof test is completed, it is best to apply a protective film on the waterproof surface so as not to damage the waterproof layer. In the ordinary waterproofing treatment of the bathroom, the walls should also be coated with waterproof paint of about 30 centimeters to prevent water from seeping into the walls. However, if the bathroom wall is a lightweight wall without load-bearing capacity, then a layer of waterproof paint needs to be applied to the wall. After the waterproof construction is completed, a 24-hour sealing test should be conducted. After the toilet is built, block all the drainage pipes in the toilet, then build a 25 centimeter high "ridge" on the door, and pour 20 centimeters of water into it.

Dig ditches, do water and electricity, conduct pipeline pressure tests, leak tests, then floor heating, and finally waterproofing. Floor heating should not be placed under the faucet, otherwise it will cause too much hot water. Underfloor heating is not connected, as long as it is not damaged by nails or other objects, it will not leak water. Before waterproofing in hydropower projects, if wall waterproofing is carried out first and then water and electricity excavation is carried out, the waterproof layer will be damaged.

Expansion: Waterproofing is no longer a fresh topic, whether it is tunnels, bridges, dams, roads, buildings, or the houses we live in daily life, waterproofing cannot be ignored. At the same time, the electrical products we use in our daily lives also have waterproof and moisture-proof issues that we must face directly.
