Ive got to install some gallow brackets for a chimney ive removed. I think the stuckal engeneer has over speced them alittle bit.
Ive got to mount 3 brackets make out of 10mm steel with 3 bolts in each bracket.
There m20 bolts which need 24mm holes 2 courses of brick deep. The only problem ive got is all the bricks where i need to drill are blue enginnering brick.
Would it be safe to install them in the mortar between the bricks. And would building control be happy with it when they come out to sign it off.
