Bulk sand bags - capacity ?

erm..... yep, it ranges between 3/4 to 1 1/4 tonne depending on state, ie wet or dry. i dont ever think they get weighed by the supplier but i have always seemed to get more that required.

tonne?)

state,

No I want to know the volume not the weight ! (but thanks anyway)

The message from "Andrew Mawson" contains these words:

According to my ancient reference 1 ton of sand is 0.83 cubic yards.

A cubic metre surely? They appear to be 1mx 1m x 1m and roughly hold a metric tonne? Seems logical to me anyway.

Logical but incorrect.

If they were filled with water then 1 cubic meter would weigh 1 Tonne (approx).

Sand is made from rock and is more dense.. but isn't packed solid.

So 1 tonne of sand varies in volume depending on the grain size and/or shape and if its wet as the water fills the gaps. I estimate that it would be about three quarters of a cubic meter at most and maybe a lot less.

The message from "The Medway Handyman" contains these words:

The one I've got in the back garden reckons max weight 800kg. I'm too idle to go measure it!

The message from "The Medway Handyman" contains these words:

They may vary in size. The part empty one I have sitting outside isn't even square. The mouth measures about 33.5" x 32" and it stands 32" high. By my calculation that is only 0.74 of a cubic yard but that doesn't take into account the way the sacks bulge.

That's about right. There is a handy table here:

Which indicates around .7 - .75 cubic metre/tonne. Well near enough given the accuracy with which this is measured anyway.

They hold a cubic metre, but they are not 1X1X1. They are 1m high, but usually about 1.35 wide each way.

To the OP: assume a cubic metre for measuring up purposes, I use about a hundred tonnes per year of sand and my working out is usually about right (for block paving - the sand is trammeled at 50mm deep (using 3X2 timbers laid flat) and I get about 20 sq metres per bag)

min 850kg dry weight.

I think sand is about twice as heavy as water, which makes it about .4 cu meters or so?
