I am thinking about buying a house with some foundation problems. The top of the basement walls seem to have slanted inward. I believe because of rain water not draining away from the house. Work has been done to fix the problem. Pilars created from concrete block are placed every 5 or 6 feet to prevent futher slanting. I am trying to find out a very rough estimate of having the house reblocked. The hosue is only 1296 sq feet. In anyone needs anymore more info please ask. Really I am just trying to find out if it will be under 10,000 dollars to fix or over 10k, or over 20k. Thank you very much.

Probably well over $20,000 when you consider that the cause of the wall movement must be found and cured, before rebuilding the foundation. Simply rain water not draining away from the house would not cause the problem. Hydrostatic pressure from constant ground water might, but I'd expect a bulge in the middle of the wall rather than the tops moving inward.

Has the movement occurred on all four walls?

How thick are the walls?

What is the distance from the top of the block to the grade outside the wall?

What is the slope of the ground outside the wall like?

Two of the walls but all four have been braced. As far as I know the wall are made of standard cement block, made 29 years ago. The distance from the top block to the grade appears to be about one and 1/2 blocks. The ground around the house does not appear to be graded and the gutters drain inches from the house.

Which two walls?

Standard block is 4, 6, 8, 10 or 12 inches thick. Try to determine which yours are.

How long ago wer5e the pilasters installed?

Rain water will not cause that much movement in the wall, Is the movement the same for the full length of the wall, or does it increase in the middle compared to the ends?

You have a very complicated problem, and there are no simple answers.

If it is a complicated problem I should not even worry about buying the house. I dont want to get in over my head. Thank you so much for your help.
