Just laid a concrete garden shed slab 3 days ago. We obviously didnt push enough concrete under the rebated edge 50mm wide x 25mm deep.
Any ideas on how to fix? If I mix up some mortar mix and try to smooth it out will it bond to the existing?
As the shed sits on the rebated edge it needs to be smooth. Slab is 2.46m x 2.46m and the shed is 2.36mx2.36m.
