Hi all,

I need to put some MOT/sub-base down for a floor-slab to an extension.
I have already put some down, but I need to top it up a little in a
few places - about 150kg or so. No where near me sells MOT in anything
other than bulk bags, though which is far more than I need, and I
don't have anything I could do with the surplus. Is there anything I
could use instead that is sold in smaller quantities?

thanks,

dan.
