Anonymous users2024-01-23Question 1: What is a caisson? It is understood as a water storage space inside the bathroom, so that the seepage water inside the toilet collects in the caisson, and then the seepage water is discharged from the drainage port of the caisson.
Problem 2: The more common caisson process has ceramsite backfill, which is to dig the caisson and then lay a new drainage pipe and sewage pipe, and then make a layer of screed. Finally in. After the water storage test is completed, the ceramsite is paved and the surface is leveled with cement sand.
Problem 3: The secondary drainage is to prevent the leakage of the water pipe inside the bathroom and the seepage of the floor to the owner's house downstairs, after all, the internal water pipe of the bathroom will leak in the case of long-term use, and then accumulate in the caisson, and finally become a leak.
Problem 4: To put it simply, if you only rely on the floor drain drainage of the brick surface of the bathroom, you can't solve the problem of internal water seepage. The secondary drain allows the toilet to leak water into the caisson and then drain away from the caisson to keep the toilet tidy and dry.
