    Anyone know? Or more specifically, how much do one of those cubic meter
    bags weigh?

    Here is a page to work it out - http://home.iitk.ac.in/~madhav/expt6.html

    if that helps.


    I have figures for sand, hardcore, cement etc. ... but not for soil.

    My guess for damp typical sandy soil you would not be too far out if you
    went at 1 tonne per m3

    Wet or clay would make the biggest difference, the latter as there are then
    no air spaces between grains.

    From the figures by L.Reid -

    > Earth dry loose 1.2 76



    so if I follow that :-

    1cu m = 35.3146666 cu ft
    1 cubic foot = 76 Lb
    dry soil therefore = 76 x 35.3146666
    cu m = 2684 Lb
    2684 Lb = 1.2 metric tonne

    which when you take my guestimate of 1 tonne ... that is not bad.

    Thanks for all your answers - some of it was slightly damp at the side from
    contact, so I'll take 1.5 to 1.75 tonnes as being close enough per bag :eek:)

    Just wanted to know how much damn work I did over the weekend - shifted two
    of the bags by hand evenly across a 40m/2 area! At least it was a little
    cooler than the weekend before ....

    having had several 22 tonne loads of top soil - and had to shovel & barrow
    away one of them - I only managed 22 tonne in a day and a half ....

    30 tonnes in a day would be way past my best effort.

    Had another 22 tonne on Friday (have to take it when I can get it) .. at
    least got this tipped out of the way so I don't have to barrow it now.

    Will have to move & level all of it ( will be 132 tonne in all) but will
    probably hire a skid steer loader for a weekend.

    Well, that I am, but not that good ;P

    The roughly 3 tonnes took me two days to spread and rake. But then I was
    painting in between when the going got too hot!

    Out of interest, is there a cheap way of buying loads of topsoil? Quality
    doesn't matter as I'm building up a base to cover over with weed sheets and
    woodchip, but "deliverability" does as it's to the back of my house down a
    laneway that a medium sized truck can fit (crane lifts over my back wall
    thankfully!). I've paid almost £100 for my two cubic meter bags.

    why ?

    So the sums are the same.

    well with 30 degree temp - all the soil in my area is well dry .... for
    once.

    I pay £100 cash per 22 tonne load ..... found a driver who hauls this for
    big companies, he takes the last load 'home with him'
    I will only take good stuff, so get a phone call at short notice ... "Iv'e
    got a load on do you want it now'
    One he dropped in the drive - hence the barrowing it for a day and a half !


    Simplest way is to look at somebody hauling it and ask them if they sell it
    for cash - most drivers don't own the stuff and always after cash.

    Wherever a new development starts up - they sell off the top soil to
    contractor, who typically gets in sub-contract owner drivers .... these are
    the guys who will sell it on.

    A new development in my area is about to start with the taking off the top
    soil from a playing fields complex of something like 30 acres to build a new
    stadium - hoping to get some soil form that.

    I bought some (20 tons) for £13 a ton, and had the local farmer dump a
    trailer full or three for free.

    Trouble is getting the tip lorry to where you want it.


    Mini diggers and dumpers will still set you back £100 a day, which often negates the lower cost of bulk buying.
