hi a very silly question for you i have to build some garden walls i will be using ton bags of basalt what's the normal ratio for cement to basalt is it 4:1 or 3:1
also what's the same for mortar is it again 3:1
finally i have to build a small retaining wall about a 700mm high for a flower bed and edge of the driveway. How deep should the foundations be 100 or 200 mm single or double skin wall.
cheers
