Hello All:
I was just wondering what the standard practice is when it comes to prepping a construction joint in a concrete structural element:
We typically specify that constructions joints be keyed and/or doweled depending on the structural element. For prep we specify that the existing concrete surface be wire brushed, cleaned and moistened prior to placing new concrete against it. In some instances we have also specified epoxy bonding agent prior to new concrete pour.
I am being told that wire brush and epoxy bonding agent is kinda excessive. Thoughts, comments are appreciated.
Thank you.
