Hi,
I'm building a low retaining wall. Over the length of the wall (17m), the height I'm retaining goes from 550mm down to zero. I have plenty of 7n 100mm dense concrete blocks, and I'm planning on 3 courses above ground.
What depth of concrete foundation would you recommend. The soil is clay, but doesn't hold too much water. It's also at the top of a hill so unlikely to get too saturated. I've ready anywhere been 100mm and 400mm, but looking for more specific advice for my situation.
Is any reinforcement needed, like rebar or fibres? The concrete will be C25 delivered and mixed on site by a volumetric truck.
I was also planning on painting the back side of the wall with bitumen paint, but should I be using a tanking slurry instead? The front of the wall will be rendered and painted, so I'm trying to avoid water penetration.
Many thanks,
CSTB
