How much topsoil?

Finnt

Hi all
I've an area of about 35ft by 15ft where I've cobble lock in my back yard, assuming I need a depth of 4-5 inches how much topsoil will I need?

magicbastarder

20 cubic yards.

Finnt

What would that be weigh wise?

9 to 12 ton bag on average. but there are so many variables to take into account

Ask the supplier, I'm useless at figuring out quantities, I always ask and they always give me the correct amount. I can recommend cabinteely landscape providers (no connection bar being a customer)

Guttervac

9/10 tonne would be about right at 5 in depth.

As others have said about 10ish tonnes will be needed. But don't buy in bags as it will cost a fortune. Try to find a bulk supplier and get it delivered loose.
Keep the €€€€€ in yer pocket.
Ps cabinteely patio centre is prob one of the more expensive places about.

Thanks all, I'm not in Dublin so won't be using cabinteely patio centre either way.
I was getting estimates between 5 and 15 tons! There's a fella local to me delivering 10ton loads for €200 unscreened might go with a load of that .

magicbastarder

is this for under the cobble lock? with unscreened, you could end up with a load of stones or other detritus in it.

I thought top soil especially screened topsoil was a fairly precious material for plants to grow in, not to go under cobble lock or indeed over cobble lock.

Unbound granular material is used for under cobble and it acts like a carpet underlay but allows some drainage and stops the cobble settling at different heights all over the place and getting ruts in it. Gravel and sand even, rather than topsoil.

Sorry I wasn't that clear, I'm taking up the cobble lock and putting down grass

I would recommend buying by the truck too,Monday I was at a job where the guy paid 50e for a ton sand in the bag I get it for 10 out of the quarry

you almost certainly don't want unscreened so. can you view the soil before you buy it?

deffinatly go and see it first , its too late when its on the ground in ur garden,

An awful lot of rubbish for sale out there. Have a google round and get used to what 'sub-soil' looks like. You certainly don't want that in the mix making up the weight. Don't let them start tipping before you have a look

Thanks for all the replies, it's on hold for now I took up some of the cobbles last night and there's a foot of hardcore under the couple inches of sand! So I'll have to find a home for all of that first!!

if its good hardcore, you should'nt have a problem gettin rid of it, a farmer might take it for a gateway

If you are only putting down a lawn, the hardcore will allow for better drainage. You'll need 6" of topsoil for a lawn, so you might have to scrape off just a bit from the top.
I calculate 8.25 tonnes required so you'll have to buy 9 at least. Buy 10 and use the extra for a raised bed?
