Back garden gate and concrete post problem

[terry004]

Hi Guys,
I have a problem with my back garden gate that needs to be replaced (see picture) the 3"x4" upright wooden post that the gate is attached to sits in the recess of a concrete post. The upright has now come off to reveal that whoever had the house before us had the post fastened with just rawl plugs and screws. The concrete fence post does not have any holes going all the way through to attach bolts. I don't really want to remove all the gravel boards, but I would if no alternative. Do you think it is possible to drill straight through the concrete post? I'm not sure as I believe they are strengthened with iron rods, any feedback would be much appreciated

Hi terry004
Yes you can drill through concrete posts but you will have to avoid reinforcing rods. How many will depend on the manufacturer. Suggest you limit yourself to a 7mm hole and use 6mm fixing bolts. You will need a fairly decent hammer drill to get through the concrete.
