Oct 25, 2008 · I've not done much of this before, but I've got a spec to install concrete padstones to support a steel beam. The spec says to use C30 concrete mix, does any one know what this is? The size on the pad is 600x100x215dp and along with the size of the attic space, I think to shutter and pour concrete would be easier than to use pre made lintels.
