In west Houston some of the homes were build with slabs nearly at grade and when grass sod was laid the garage and parts of the house slab ended up at or below grade. So now when we get down pours water can leak in under the slab to wall plate seam.

I put in french drains around the garage and actually lifted the garage and put in a course of cinder blocks to solve that the problem there. The back of the house is another matter. The french drains I put in can get overwhelmed and I still experience some water entry along the wall of my office.

I was toying with the idea of sealing the area of the brick veneer-slab seam to prevent water from seeping under the wooden wall plate-slab seam with a sealant or even tar. I figure a good sealant applied up a coule of inches onto the lower brick of the veneer would be adequate unless we have another Biblical flood.

Does anyone have any ideas or solutions for the problem or suggestions of a sealant that I could apply?
