Concrete spall repair
May 20, 2015

I have about 150m of fencing ... created by using concrete H posts .. on a couple of them the concrete has spalled off ... about 3" or so about 3/4 wide exposing the reinforcing bar below.
I need to treat and fill to prevent spread.
I thought of painting exposed steel with a rust conversion preparation .... and then filling the void. I could use a mortar mix and cement PVA adhesive, or is there a better approach.. maybe a gunnable cartridge product made for this.
EVA. Or SBR. Epoxy mortar would be better of course, but £ouch.

Good idea EpoxySet 105 is £20 for 2Kg ... but cheaper than replacing any posts :-)
I have 5L of SBR in the garage
