Question from mark:

how many tonnes of hardcore/crushed stone would it take to fill 1 hole 9ft diameter 5ft deep and 2 holes both 3ft diameter and 5ft deep

Hi Mark,

You can find the volume of stone you need using our volume calculator. The weight will depend on the density of the stone .I would ask the business where you plan to purchase the stone or search the internet.
