These rocks would of had far greater crush resistance than modern concrete blocks .
Furthermore, how deep should a concrete footing be for a retaining wall?
A concrete footing should be 100mm deep by 300mm wide if the footing is for a free standing wall. The footing should be increased to 150mm deep and 450mm wide if the wall being built is a retaining wall. For larger retaining walls an engineer may need to be approached for advice.
