600mm deep, 150 concrete.
250mm wide, but depending on the width of the blockwork.
I'd like to use standard 100mm blocks single skin as I reckon the planter on the front of it should give it a lot of strength anyway.
what do you think?
I need to build a blockwork wall, around 2m high, with a 1m planter built onto the front of it, what thickness does the wall need to be and how many piers should I use?
Thanks :D
