ok so finally I have decided to lay a foundation my self using this method:
I have calculated for my Garden I need 3.1 Meters by 3.95 Meters and will use 95 slabs 400x400.
I am going to this 6mm to dust https://www.diy.com/departments/tarmac-grano-dust-bulk-bag/165422_BQ.prd
I will need some sharp sand and cement the area I need to cover is 12.25m2 how do I know how many bags I need of each?
Cheers
