Frequently asked questions
Water came up through the floor drain rather than in at a wall. What does that mean?
That the public sewer surcharged rather than the foundation leaking. Water arriving through a fixture during heavy rain is Category 3 and carries sewage, so the scope is disinfection and porous material removal rather than exterior drainage. The two failures look identical on the floor and are not related.
The house is from the 1920s. Is a dry basement realistic?
Managed, yes; sealed, no. Brick foundations of that period were built to carry load, not to exclude moisture, and the damp-proofing layers taken for granted now did not exist. Controlling surface water and keeping the perimeter drained accomplishes far more than treating the inside face of the wall.
Does a backwater valve solve sewer backup?
It addresses the specific failure of water entering backward through the lateral, which is the mechanism here. It does nothing about groundwater or surface water, so it is worth understanding which problem a given basement actually has before installing one and assuming the question is closed.
