Foundation crack – how would you fix it
I’d like to get other opinions on how to repair the foundation crack in the attached pictures, and how to find a competent contractor to do this kind of work. This is outside the scope of our work and experience.
The inside crack extends from the middle of basement window to the floor and is wider at the top. The window is about 4′ from the corner, and a downspot and tile at the corner was clogged. We placed new drain tile to fix the downspout, but the water from the downspout was apparently hydrating the clay soil, as the crack worsened over time as the soil dried. Currently the crack is around 1/2″, but is still moving maybe 1/4″ as the seasons vary.
Client has talked to the basement waterproofing/pier folks and was not happy. Estimates ranged from $2,000 to $25,000 for essentially the same work, with no guarantee it would fix the problem.
Brown recommends drilling concrete piers, lifting off that, then dry pack the gap. Seems feasible, but can’t find anyone to do the work.
It does appear that the downspout water undermined the corner and that the corner dropped, probably breaking the footer. Construction is brick veneer over balloon-framed studs.
How would you fix this to make sure it stays fixed?
