Hi, I’m just in the early planning stages of a self build annex and one side of the building will be built into an are that will act as a retaining wall. what’s the normal way that the wall is built to hold back the soil and to prevent any moisture penetration. it’s a single storey annex and the sheight of the soil/ground is around 1.2m above finished floor level. I’ve attached a pic
