den321 Posted January 26, 2021 Share Posted January 26, 2021 I have a run of fencing with concrete posts/gravel boards going down one side of the garden. My garden is higher up than the neighbour on the other side of the fence. So when it gets to the end of the fence run the ground drops away too far down to be able to fix the final post into the ground. So the original fitter attached the last post to the retaining wall - unfortunately made of breeze block. After not too long the post came away from the wall, as the fitter had only used one fixing, which turns out wasnt the right fixing or long enough. He wouldnt come back to fix it. Had someone else come along who replaced the post with a longer one and attached with 3 bolts. Looked very sturdy but after 2 days (after a bit of wind) the post has come away again as the bolts havent held. They are coming back to try using even longer bolts. But because its a breeze block I'm thinking a better solution would be to use both the bolts and a chemical fixing - as in, Epoxy/Injection resin into the bolt holes to hold the bolts . Does anybody think this would be the correct solution? Thanks Link to comment Share on other sites More sharing options...
Pyrotequila Posted January 26, 2021 Share Posted January 26, 2021 I'm no expert, but with them being hollow blocks, would they not get better grip from using some substantial hollow wall anchors and bolts? Link to comment Share on other sites More sharing options...

Drill to full depth of breeze block, chemi in, threaded rod in to full depth of breeze block. Let it set then tighten it up. Link to comment Share on other sites More sharing options...
spider1 Posted January 26, 2021 Share Posted January 26, 2021 If its pulling out when its fitted properly and you keep re fixing you will finish up pullingwall over. Get a longer post dig out put new pole in get plenty concrete round it Link to comment Share on other sites More sharing options...

Thanks Try some Ankerbolts, really easy to use and they get a real hold, if you put 3 - 4 of those in its going nowhere, make sure you get the exact size drill bit for the bolts.

iansheff Posted January 27, 2021 Share Posted January 27, 2021 If you cannot get a post that is long enough why not get either a trip of flat bar or 4 pieces say six inch long, drill straight through the wall in 4 places and use screwed thread to bolt it through the wall. That is assuming the person on the other side of the wall doesn't mind. Link to comment Share on other sites More sharing options...
willman Posted January 27, 2021 Share Posted January 27, 2021 I'd be tempted to get a longer post or use a knock in metpost (if possible) to get some gepth into the ground witht the pole protruding. Never been a big fan of anchoring anything into breeze blocks personally. Link to comment Share on other sites More sharing options...
