Hi I'm building a single skin concrete block shed onto the back of existing outbuilding I've poured concrete for footings and was going to use 5 course of engineering bricks upto dpc but my mate has got me some trench blocks so would only need 1 trench block and 2 course engineering upto dpc.
My problem is the trench blocks don't fit to line the face up with the line so can I run them so the line is down the centre of the block and engineers on centre of the trench blocks or do you have to build flush to the face of the blocks ?
