Thank you for such a great response
The guys we got in to do the wall and steps have done a great job (have included photos of how it had been left by the cowboys we had in the first time). It’s hollow block with rebar and filled with concrete so unlikely to go anywhere!
The joints at the bottom are open for drainage, there is a gap at the back that has been backfilled with rubble and gravel for drainage.
Not sure on BC, not an acronym I’ve come across. However, we will need to add a hand rail and something along the top of the wall as it’s over a metre drop and we want to keep the kids and puppy safe.
For the steps the plan was to use porcelain on the tops, doing the same on the wall tops. Ideally I’d like to render the risers but am aware this could be a fiddly job, especially for a beginner, so backup would be to use porcelain on the risers as well.
From what I’ve read it seems it’s best to render before laying the patio, although don’t know if the steps/copes need to be done first or if I can just use a straight edge/feather board to get the render right.
Would love to be able to get someone in to do the job but quotes have been £900-1200 and we just don’t have that at the moment 😢
