Re: Old Dirt Basement
Seems to me that a reasonable solution (without replacing the foundation entirely) would be to keep the water from getting to the foundation in the first place. This means digging a trench around the entire house, placing drain tile and drain rock in it, and directing the outlet of that drain tile to a location on your property that is lower than the house. You could at the same time redirect the flow of your gutter downspouts. If your house is already at the low point, this may not be practical.
One potential problem with doing this is that the foundation may depend on the surrounding soil for structural support, and digging a trench near or next to the foundation could cause it to collapse.
The $50,000 guesstimate probably involves jacking up your house and putting a completely new foundation under it. The above work would probably be around $10,000 and may improve the situation, but you would still have an old rock foundation and a dirt basement/crawlspace. But that's a guess on my part, too.
