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
