Older Heavier Bricks On Top of New

[DitchManPete]

Hi,

Has anyone got an experience using an reclaimed heavier brick on top of a new lighter weight brick?

Im building a 3m high cavity wall and have laid up to the DPC with 73mm x 100mm extruded engineering bricks. My intention is to now lay the rest of the courses using reclaimed 75mm x 105mm bricks which are heavier and wider. Any worries, thoughts or tips?

Same question applies to using concrete blocks on top of engineering bricks although these are at least 100mm so same depth.

Anything I could do with the lower courses of bricks, use cement rich mortar maybe?

Worries: none
Thoughts: get on with it
Tips: put the 5mm overhang into the cavity side

To what end? making the pointing change colour part way up the wall?

Engineering bricks are designed to take weight.

Depending how visible the bit below dpc is you may want to lay the longer bricks with skinny perps to keep the bond. Apart from that minor consideration there are no issues, crack on

I think all bricks are

I should have said that engineering bricks are designed to take more weight than a standard face brick.

I'm sure you remember the commons below ground before the engineers.
