We are considering buying a building apparently built over a spring
which is now causing problems.
Would a french drain eliminate the problem? We would like to keep the
structure where it is. any ideas?

I built a cabin using wood piles in a place called many springs(you
can guess why). Before I built it I build up the site after laying down
hundreds of feet of weeping tiles in the trenches, poured 30 truck loads
of gravel/sand/clay/top soil altogether. Waited two years and when
engineer said, it's OK to build. I built a two story structure.
No problem so far. It's been 5 years. So, retrofitting any measure is ??????
Unless you must want to buy it for some reason.......................

Without seeing your situation in person it is hard ot reccomend a solution. I
would get a couple of companies in your area that specialize in that area to
come out and take a look at the problem and what the solution if any might be.
My parents house that I grew up in was built on top of an underground
stream. The basement was always damp when we first moved in and when it
rained we always had a wading pool.
They wound up having to chop up the perimeter of the basement floor to
install drain pipe and got 2 sump pumps (One at each end of the basement).
The dampness subsided and the flooding stopped, but those pumps ran
constantly whenever it rained and for days afterward. My father always
complained about how much electricity the pumps would consume.
If it was me, I would run the other way. Your problem probably could be
resolved, but it will cost money and additional headaches. You should also
consider the mold and mildew that result from moisture.
When our house was built 20 years ago, it was after several dry years. The next
year had normal rain and we found out the house had been built over a spring.
We put in two sump pumps which ran constantly and we still had times when we
flooded. The house is about eight feet above the road and we finally put in an
8" pipe that connects to one sump pit and runs diagonally across the yard for
about 200 feet to the storm drain in the street. There's water in the pipe most
of the time but we've been able to cover the sump pits and the basement has
been dry enough to finish. There is some kind of device in the pipe so flooding
at the storm drain could not back up into the basement. This was done about a
dozen years ago and seems to have done the trick.
I agree with Rand. Many years ago, I was involved with new
construction that opened a spring under a house. It was capped and
piped under the house to the down hill side. That said, someone
kowledgable is going to have to look at the specific conditions before
a solution can be proposed.
