reinforcing existing foumdation
(OP)
we are repairing an existing porch with roof on 80 year old house. it has a masonry foundation, however no footing. the foundation is +/- 3' below grade and extends 2.5' above grade. it is obvious that the foundation is sagging which is causing the problems. the existing foundation is to remain due to costs to remove/rebuild. we are looking to shore up the foundation at the corners and under each porch post. what is the most effective way to do this?

I think the best method is to support the roof of the porch first. This can be done with timbers angling slightly over to wood plates on grade. When you are satisfied that the roof is adequately supported, it should be safe to carefully underpin the masonry wall in sections.

It may be difficult to install helical piles, especially if these are unreinforced masonry walls.

Please, all you advocates of helical piles advise how they can be installed where required?

It could be a downspout that is releasing water too close toi the wall causing settlement. If this is the case, the downspout disgharge needs to be directed further away from the building or tightlined.
