I have a problem, a friend arranged some concreters to come around and pur a slab for my 3x3m shed, unfortunately they made the slab 3x3m instead of 3.1m x 3.1m now the shed won't fit properly because the rolled edges.
I now can't afford to get another concreter in, and can't get the other people back to fix it.
What would be the best solution to fix this?
build a form next to the old slab and add the required cement to extend the slab. Add rebar drilled and anchored with epoxy to join the old and new slabs. Be sure to add the same depth of gravel under the slab extension.
