external ground level should be 150mm (min) below dpc.

this generally leaves 2 bricks visible below damp.

it is these 2 courses of bricks that are the most vulnerable to frost.

the bricks lower down may absorb water also, but are not as exposed to the freezing weather.

only a complete fool would risk laying an absorbent brick below dpc, regardless of b'regs or architects specifications.

and do you use conc common brick for the first course or concrete block ?

read this fastnotroll.

woody advised not to use common bricks. in certain parts of the country 'commons' are regarded as an inferior soft clay brick. this was good advice.

it was YOU who has gone off on a crusade about fletton bricks and their uses.

i merely backed up the advice about the problems associated with using soft clay materials below dpc. ffs.
