Toilet waterproofing
The structural layer of the bathroom shall be waterproof, and waterproof flanging shall be done. The height of waterproof flanging must be more than 200 mm above the ground after decoration, and the flanging effect can reach the situation that the corner of the adjacent room will not be moldy due to water leakage.
Drainage pipe laying
After the drainage pipe is laid, it must be watered to prevent water leakage. There should be a foundation under the pipeline to prevent the deformation of the drainage pipe caused by the pressure bending of the upper part in the future, which will affect the performance of the pipeline after long-term aging, and there will be cracks and water seepage at the interface. The drainage pipeline must have a slope to prevent water accumulation in the pipeline and facilitate the erosion of sediment at the bottom of the pipeline.
Filler light particles
Fillers should be light particles, fly ash, etc. , but not concrete, so that the pipeline can be easily replaced in future maintenance.
Leveling layer waterproof
The leveling layer should be waterproof, the concrete of the leveling layer should be added with impermeability agent, and the waterproof ointment should be applied after leveling. Then it should be noted that the ground must be tilted to the floor drain after completion to prevent water accumulation on the ground.
Threshold adjustment
If the ground is higher than the outside of the bathroom after completion, then the door of the bathroom should be set with a threshold, so that in case of an accident, water will not flow outside.
Drainage toilet on the same floor
The drainage toilets on the same floor can be relocated as long as the drainage problem is solved.
Drainage toilets on different floors
Attention should also be paid to the above problems of 1, 2 and 5 in the drainage of different layers.
