Can weep holes function properly if they exist on the bottom course of brick veneer and the bottom 2-3 courses of the veneer are buried by dirt. The dirt needs to be graded higher around the house to achieve the proper grade going away from the home.

I'm thining this would not allow proper air flow behind the veneer and would not let out the condensation and moisture building up behind the veneer.

Can a solution be used where sheet plastic (visqueen?), and gravel are used along the first few courses that are buried? The visqueen would act like an extended flashing extending 2 - 3 feet into the yard and would be covered with pea gravel and then soil.

Also, I am currently planning on replacing the same half wall of brick veneer. This veneer sits atop poured concrete foundation walls. Should I take this opportunity to somehow raise the foundation walls before replacing the brick veneer. Also, I am planning to use NovaBrick in the repalcement of the veneer, which allows you to 'hang' the brick siding rather than securing to the previously notched foundation wall. What is the best route to go at this stage in the rehab process to ensure that I can grade higher around the home while replacing an existing half wall of brick vener with NovaBrick siding?

Thanks in advance for any help you can provide.
