sagging floor

[Dave]

Hi there,I have a sagging floor and a nagging wife he he .Anyways I
had an Inspector tell me the sag is in the middle and is about 4 to 5
inches.In the Basement there is a small concrete wall about a foot
high and a foot thick running about 3/4 the length of the basement
and a timber beam above it,Im guessing helping to hold the house
up.The house was built in 1915 here in Vancouver Canada.THe inspecor
told me he is guessing but maybe years ago water came in the basement
and pooled in the middle causing the cement to soften there and after
time the house settled.What do you guys think I can have done to fix
this problem without you actually seening it.By the way Im no fool I
always get a proffesional

Thanks Everyone

Water softening concrete? I'd not trust the professional that told you
that. It may erode the footings or do other damage, but not soften it like
heated wax.

In any case, sagging floors can be fixed. You have to be sure you have
solid foundation. That may mean cutting out a section, digging deeper and
putting new concrete. They you can put in a steel pole and jack to raise the
floor. It must be done very slowly and perhaps done in a couple of spots.
There is a limit as to how far you should raise the floor at a time because
you want the rest of the structure to acclimate slowly also.
