We are just about to start our new build house, the builder is
supplying labour and us the materials. Foundations are due to start in
2 weeks, builder has asked for a small qty of bricks to edge the raft
foundations to 3 courses(to damp). I have seem these done in
engineering bricks on sites before, with standard finishing bricks on
top, I have also seen standard facing bricks all the way down....
Aesthetically it surely looks better if the bricks are all the same,
so I'm guessing this has something to do with the strength and other
qualities of the engineering bricks? If this is the case why is it
optional... my architect and LA regs haven't mentioned them?

Thanks.
