I am going to be forming a driveway with 10 or 20mm limestone chippings.
I have already excavated to 100mm below grade. The surface is hard soil, and a whacker would do very little to improve it.
Which would be better on a driveway? 10 or 20mm?
How many bulk bags will I need for an area 4.8x4.2 metres?
What barrier should I use between the soil and the gravel? The old drive had a plastic sheet (really crap to dig out and held water). Do I need to do anything to finish the gravel off? Will the weight of the car compact the gravel together? I read that the larger gravel will bind together better over time.
On a related note, will a masonry bit drill a hole in a tarmac pavement? The gates on the drive will open outwards due to the above dimensions, so need to be anchored open while I drive the car in.
