Hi, I’m not a plasterer so please bare with me. I am going to employ a plasterer to do the rendering job once the wall is complete. And my landscaper is building the walls.
I’m looking for a belt and braces solution to last as long as possible.
I am having some retaining and raised planters built in my garden. They are gonna be built in block and have the following structure:-
Damp proof course
Block laid sideways (to create wide wall)
Bitumen paint at soil side
Damp proof membrane on top (laped into block)
Land drain (to avoid weep holes)
Render on top
No coping
Please see diagram
My questions are:-
Should I put some waterproof slurry on the non soil side that will sit under the render?
Does there need to be a gap between render and ground flags?
can you render over the DPC?
Without coping stone should the render be angled to drain water?
Which render will be the best for the job in hand. I’ve seen people recommend sand and cement, one coat and others - is there a bullet proof solution here? Ideally I want it to last as long as possible with minimum maintenance.
Is there anything else I can do or change to do this right?
I appreciate that the firm I employ to do the render will give me some of my answers but obviously the wall is about to be built and I’d like to be straight in my head what needs to happen so I don’t get a s**t job.
Cheers
