So I've just moved in this house built in 1997. The basement is finished (carpet and dry wall put up) and the carpet in an area along the east wall is wet. The previous owner disclosed water he had water problems the last two springs (but not the first in 1998), but claimed it was fixed with some re-landscaping.
I'm about to spend over $3000 to do landscaping in an attempt to correct the problem. The landscaper making the bid pointed out several reasons why the apparent do-it your-selfer job the previous owner tried quite likely had no effect whatsoever is re-routing draining water. Judging from the exterior slope it does seem that re-sloping everything away from the house could do a lot of good.
My conundrum is this. I've heard that another likely scenario is that the drainage tile (8 feet down along the entire back wall in my case) is not functioning properly (i.e. broken, crushed, blocked, etc.). To fix this I'm told is a costly problem (around $10,000 )since it involves extrememe care with a back-hoe (care not to accidentally push in the foundation while digging).
But why spend the $3000 on re-sloping first if it is bad tiling? Which comes to my question. Can one check whether the tiling is any good before digging down 8 feet and spending ten grand? Or doesn't it matter if the drain tile is crushed and blocked if slopage solves the problem anyway? I'm wondering if they can stick a roto-router type thing through the drain tile starting from the basement sump-basket in an effort to check that all the tile is clear. Or is there some other way to check the tile before proceeding further. There is a window well with drain tile at the bottom. Is it possible that this connects with the tile around the house and I could hook up a garden hose to it and see if water flows around and into the sump basket in an effort to see if the tile is clear? It seems that there would be a less expensive option in determining whether the tile is damaged before spending the big bucks to dig down and fix it. Can anyone help?
