I have a brick house, and a cement foundation. The brick extends about 6 - 12" below grade before it gets to the cement foundation. I've been told that I need to seal the seam on the exterior to prevent water seepage between the brick and cement (which we do get durring heavy rain).

Any ideas about what to use for sealing? I was at the Home Depot, and saw nothing specifically for this. I suspect that I may be able to use some sort of roofing tar.

Ideas appreciated.

I doubt that that seam is the source of your water intrusion, because the conceret foundation probably extends all the way up behind the brick, to the bottom of your floor joists, almost.

Before you start throwing tar all over your house and maybe still not solving the problem, why not do some testing with a garden hose, to determine exactly where the leakage is occurring. Maybe all you have is a couple of leaking tie rod holes. Maybe you have a crack in your foundation. You can't prescribe a medicine when you don't know the disease.

One thing you may want to look at before you do anything is whether the backfill against the house may be too high. It is not uncommon for brick veneered walls to have weeps at intervals to allow condensation to escape. If over the years dirt has filled in around the base of the house, it may have reached a depth where it is now covering those weeps, allowing water to enter, rather than leave the structure. The weeps will likely appear as slots between bricks that appear to be missing mortar. Many people make the mistake of mulching planting beds located next to houses to a level above those weeps, which then creates water infiltration issues.

If the weeps are flashed properly, water cannot infiltrate into the house. The problem comes in residential work when brick veneers are often not flashed properly. Unfortunately, it is next to impossible once the wall is built to determine whether there is proper flashing at the weep holes, without actually removing some bricks, and it is absolutely impossible to retrofit flashing when the wall is finished.
