For a 1930's build house, how soon - or would you - expect to see
water damage if you get flooding to within an inch of the damp
course ? (patio was 4-5" below water approx)

....either to foundations / internal floors which are unlikely to have
a damp proof membrane etc.

If not as a one-off, how about on an ongoing basis at least annually
now ? (slip / heave etc. - we're in a clay soil area)

If this was a "new" phenomenen caused by the erection of a new
building that effectively created a dam against the natural drainage
of the land for the proceeding 70 years, who could you claim against ?

I wouldn't expect to see any, based upon the fact that, until fairly
recently, that was a normal winter occurence for my 1931 house. The water
table regularly came above ground level until they installed pumps in the
land drains.

I agree with Colin

If, hypothetically, you had suffered loss as a result of someone doing
something that caused you a flood, you would be suffering a
"nuicance" (water entry) as a result of his activity and in theory
could sue him. I would not like to be paying the expert witnesses that
you would need to prove causation! He of course, would have recourse
to his designer and possibly the local council....
