Can anyone tell me how much sand I will need, I am laying a block paved driveway, area 55sq meters.
I have dug it out and using alot of the concrete that came out as hardcore for base. I will need extra so do I need Type 1 hardcore base? if so how much should I order.?
You will need approx 10.9 sub base at 100 ml depth, dont know how much you have, or if it is suitable size wise. if it is then you could cut the volume down. Sand at 40ml 3.9 at 50 ml 4.8.
