Wall corners and pipe roots/shop refurbishment

The "wall corner" here mainly refers to the inner corner (the joint between the wall and the ground) and the "pipe root" (the root of the through wall water pipe and toilet drain pipe).

Leakage phenomenon: The corners of the wall have been damp and blackened for a long time; The ceramic tiles around the base of the toilet or sink water pipe are hollow and have yellow water stains.

Reason for water leakage:

-When doing waterproofing, the corners and the roots of the water pipes are stress concentrated areas. If the waterproof coating is not applied to the rounded corners or reinforced with non-woven fabric, it is easy for the coating to crack due to later thermal expansion, contraction, and building vibration.

-The aging of the toilet flange (sealing ring) causes sewage to leak around the sewage pipe.

What should I do?

Judgment: Carefully observe these connections. For the toilet, you can pour water into the area where the base of the toilet is in contact with the ground to see if the leakage is worsening downstairs.

solve:

-For wall corner/pipe root cracks: Plastic steel putty or elastic waterproof glue can be used for surface sealing, which is an extremely low-cost DIY attempt.

-For the toilet flange issue: there is no need to smash the floor tiles at all! Just ask the master to open the toilet and replace it with a high-quality new orchid ring to solve the problem.
