Bricks, Masonry, Asphalt and Concrete - Washed out brick in West Texas

my home was built in the late 80's using what is now outlawed mexican brick (city ordanance). The previous owner used the wall to water his flower bed. The sprinkler system was aimed for the wall, then wash gently down the side to the plants. I have closed off that part of the sprinkler line and removed the bed and sprinklers. Now, what I have is half bricks in spots and washed out bricks with mortar showing where the center of the brick was, or used to be. This goes about half way around the house, and it's all the bottom 4 rows. Other than call a contractor to do the repairs at 1k$, what can I do? The house is 11,000 sq.ft. and i will need 234 bricks to do the job correctly,or 123 bricks to just replace the washed out bricks or a half correct job. My problem is the common brick laying pattern, and the correct motar spacing, so at some date it will look close, in the future.

I am a little confused about your question(s) (not what has occurred). First you say "what can I do", (other than call a contractor), then indicate your only problems in performing the work are matching the bond pattern and spacing.

For bond patterns consult tech note 30, & the glossary tech note 2 at http://www.bia.org/html/frmset_thnt.htm For help in spacing control purchase a tuckpointing trowel in the desired width or make a spacing control tool.

I may be out of line (been there before), however, the compressive strength of the brick and mortar should be the same or less than the original brickwork.

I'm guessing, but the mortar may be Type S with added lime and more sand than usual. 1 Type S masonry cement, 1 Type S lime, and 6 sand is the starting point. Confirm mix proportions locally. Holnam http://www.holnam.com/ is well know supplier of cement products. They have a plant in Texas (at times they offer technical assistance).

Depending on construction & loading around 2.5 feet of 2 courses (or more) may be removed safely, then replaced.
