I am thinking of building a retaining wall, using up right sleepers 1.0m high above ground level with 500mm in the ground.See Example
I will be using 1.5m x 250mm x 125mm or 75mm but im not sure which thickness. I would like to go for the 75mm thick sleeper (Cheaper) but not sure whether it would be strong enough. Which should I use? any help will be greatly appreciated.
