HI!
I’m not sure where to post this, but I’m in need of direction and some sound advise. I would like to raise the grade along the exterior wall of my garage some 2 feet above the present foundation/grade. The garage structure is stick frame with brick facing. The reason for the change in grade is because I’m changing the exterior entryway to the house. I not sure if there are weep holes in the brick as I couldn’t see any but the house was built mid 1980. After the grade is raised I plan to pour a slab to the wall of the garage. If this isn’t practical, I can use a steel grate to cover this hole and still be able to have drainage using drain tile.

So you want to raise the grade above the foundation, to where it's resting against the brick veneer?
Either you gotta raise the foundation in that area or put a "well" there, so the soil isn't against the brick.
with extremely carefull detailing of the drainage and waterproofing details (draintile to daylight or sump), waterproofing, parging, and then drainage mat before dirt, you could take the risk (most weep holes don't weep), but to do it right you would want to raise the foundation to above grade....
I agree that with careful detailing you can make this work. You should provide for drainage at the grade where weep holes exist then use a product like Rub R http://www.advancedcoatings.on.ca/rub-r-wall-airtight.html to coat the brick that is to be below grade, apply a drainage mat, then backfill with #57s with filter fabric over before finishing with dirt. I would also be assured that the wall sheathing is covered by housewrap or felt paper. If it isn't you'll only make a serious problem worse.

Thanks All,
Raising the foundation is too costly, eventhough there is just 10 feet in length of foundation to raise. I do have "draintile to daylight" already installed for the down spout from the roof gutter.
I'll talk with the regional building department as to what is acceptable and post my solution. Thanks again!!
