How often should waterproofing be done?

[ruslanovna]

To be honest, I don't know how often waterproofing should be done. But it seems to me that the previous owners of the house that I bought did not know about this in principle. I somehow did not see when buying that in the basement they have a real water kingdom. A little more and in my basement one could see real stalactites and stalagmites. In general, I called the masters from POM Waterproofing https://pomwaterproofing.ca/exterior-waterproofing/damp-proofing/ and they helped to eliminate the neglected consequences.
