Strengthening Joint Between Slab and Footing
I just poured my 750 square feet slab with help from somewhat experienced friends. Everything went well except there is an obvious joint between the footing which was poured first and the slab which was poured last. See the picture.
We poured the footing first and as per the concrete suppliers recommendation we used an accelerator for the footings and then used water reducer for the slab part so we could finish it with time to spare. However it looks like we did not mix the two different pours well along the form boards.
My question is what joint compound or epoxy would folks recommend for me to fill this joint along the outside, and/or is there something else I can do to help these cracks from getting bigger and/or strengthen this area where the walls will be bearing.
