Hello All, I need some advice.
I have an addition on a 1920's house (addition built in the 50's or
60's I think). It is fairly small probably 6*6 or there about. It is supported by the house on one side and two cinder block pillars (it looks like). It appears that the pillars have sunk or something because the whole thing slopes downward toward the pillars. The pillars themselves I assume were built straight up now slope slightly inward and at a slight angle away from the house (would they have been built like this on purpose). Neither exhibits any movement or flex, but the floor of this thing is very bouncy. I would like to put a washer and dryer out here (the space is enclosed), but am afraid it may fall down or something. I was not able to find any rotting boards in the floor (it is exposed from the bottom).If I were to jack it up using a jack (what weight is recommended) would it be acceptable to use 6*6 square pressure treated supports dug in and cemented into the ground? How do you join these as they will probably have to be longer than the eight feet I have seen at home depot? Also how much cement needs to be pour to stabilize them? Anyone know what the frost depth line is in Fred, VA.
Unfortunately I can't afford to pay out anymore money on the house as I already fixed a major sag, new kitchen and new bathrooms (and to boot had a miserable contractor who I am still fixing damage from).
Any help would be appreciated.
Thanks, Geoffrey
