How much gravel do I need for my trench?

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton). The final figure will be the estimated amount of tons required.

How much gravel do I need depth?

What depth of gravel do I need? You would usually lay a 10mm aggregate at a depth of 30-40mm, but on a driveway this would need to be at least 50mm. A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones.

How do you prepare ground for gravel?

Ground preparation

  1. Clear the space of all vegetation.
  2. Remove weeds and carefully take out plants you want to keep and introduce back into your gravel garden.
  3. Dig over the ground once or twice to enhance the condition of the top layer of soil.
  4. Rake well to even out the surface and break down any lumps and bumps.

Can you lay gravel on top of grass?

The answer is yes – you need to remove the grass and expose the soil before laying down gravel. It’s not a good idea to gravel over grass without removing the lawn first. If you leave the turf in place, rather than replacing it, this will result in a very uneven finish as the grass decomposes over time.

How to calculate how much gravel to fill a box?

For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft, you need to multiply 1ft x 3ft x 6ft = 24ft 3 (cubic feet) of gravel, then multiply that by the density. Our gravel calculator handles all this for you given you supply the dimensions.
