I am in the planning stages of building a 3m long retaining wall with 2m wide steps in the centre. I am planning on constructing this with forms and pouring concrete.
I am designing the steps to have concrete slabs on top for a nice finish so want to work out the tread and rise that gets the steps finishing at the correct level.
I have calculated a 400mm tread with a 150mm rise to be correct but I want to cater for the mortar when doing my calculations.
How thick does my mortar bed need to be when laying these slabs?
