"repaired" cracked foundation and second story

[Dave Phillips]

I purchased a house in Edmonton that has a horizontal crack the entire length of one wall as well as at least one vertical crack.

The work has been repaired but the seller never disclosed that the crack was there until after I ripped down some of the drywall and exposed the cracks.

There is an engineers report that says that the wall has been repaired and has been restored to "structural adequacy".

They installed an interior shoring wall of pressure treated 2x6's with staggered pressure treated blocking that is tied to the floor as well as the joists.

I purchased the house with the intention of adding a second story.

I am wondering if it will support the second story or whether there is more that I should do before I start building.

The original foundations in the area are such that they should support a 2.5 or 3 story house without issue.
