If this is not the place to ask detailed info on foundations, please direct me to another forum where I could ask such questions. Anyway... I have a 1300 sq ft house with a bedroom that is approx. 14x11. The problem is that a 9 x 9 foot triangle of the corner is dropping down about 6 eights of an inch. The triangle is 9x9 and 14 at the base. Hope you can visualize that. The 14 foot base is leading further into the foundation. I've had a guy come out to put piers in, but this corner is till down after about 3-4 years. Is there some reason not to put a pier right at the apex of the corner? I have a crack in the dry wall seam and when I place my 9 foot level down it is about 6/8 inch down. I know some will say just water and it will rebound but I would like some sort of better insurance it will not drop again. This is in Texas and I had the guy come out and the rest of the house is good. Just this corner is the problem. There is a 30 inch drop from the corner to the bottom of the next house level. I know this is probably the problem cause everything wants to go down hill. Any opinions are good. Just want to get some opinions before I get some more bids on further work.
