area calculation

[niftysteve]

Been asked to re gravel an area in front of a posh block of flats. I've measured the area but I'm useless at working out how much gravel is going to be needed. What is the best way of working it out

 

1 ton of 20mm stone will cover an area of 15 square metres at 35mm cover

1.75 is wet from the quarry. Builders bag is a very expensive way of buying aggregate but convenient for small quantities. Could be up to 3 times the price / tonne depending on your deal with the quarry.

It is not a cubic metre as some think. Might have been a tonne at one stage but I believe it is now 900kg. No guarantee on that figure though.

 

They now work on 800kg for transport purposes

So even more expensive. I am sure they have put the price down when the bags went lighter. I normally buy a lorry load in the region of £12 to £18 / tonne delivered depending on what material. Ideal if you have the space to store it, a hard surface to tip on and ideally a wall behind for loading.

800kg if its 20mm as just had ten bags.

No chance of a ten ton tipper load being delivered then? Bit far for you CP but if anyone is in the plymouth area I have some good contacts.
