Split level vs retaining wall
I have excavated ready for garage slab just needing final detail.
I am trying to understand the theory in building options what would be different as it slopes from front (zero height) to back ~1.2m high.
I was thinking of pouring the slab and have starter bars coming out and besser block upto 1 m high core filling it then waterproof behind and backfill.
Or
Retain separately with a gap between the garage and back wall. The side walls can also become part of the structure or I have approx 300mm gap between retaining walls on each side.
Or
Build it as a split level as behind it at the 1.2 m end I need to shape/ level anyway, by doing this way I assume it prevents the retaining wall from " topping over and eliminate a giant base footing or base thickened raft slab is this correct?
At the back I can put stairs in after.
An engineer didn't sort of understand what I wanted.
As 2870 has a picture of a wall 200 mm thick but it doesn't mention any backfill against it just waterproofing.Detail for footing and single leaf reinforced masonry wall combo. Which is good for single storey height.
