Concrete fence post

[diycooper]

Last year I put up one of them concrete walls, where you put the post in then slide the slabs in. What I want to do now is remove the gate and put slabs there to as I have 2 gates. Where the gate was I used the posts without the grooves, to save taking them out do you think it would be possible to use a grinder to cut grooves into the posts to slide the slab in, then at the top of the post where it may look abit untidy mortor it flush. As it getting painted I do not think this would look bad. Just need advice on what you think about cutting groove in post with grinder ?


Thanks

suppose you could cut grooves with a grinder or abrasive wheel or diamond saw!!
I assume you want to do this in situ so would have to dig around the base to allow the "radius" of the saw bury itself and give you a deep cut all the way to ground level!!, suggest also you do three min..poss four...even five cuts, the outer cuts would benefit from you clamping a guide timber to allow neatness.

Personally this is a bit of work and would probably put in a couple of new posts!!..however if your surfaces are finished and you don't want to disturb them by removing and placing new posts....Give it a go!!

you will probably get a bit of dust going...I always try and get a job that involves grinding cutting concrete done on a windy day as it helps remove dust from your work area...suggest tuesday were in for a battering!!!!

Assuming you can avoid the stell it should work. A good quality diamond blade would make short work of it.

May be worth making yourself up a quick guide/jig to help keep it straight and square.

Thanks guys, and the guide is really good advice. cheers

Surely cutting the posts will not only weaken them but risk exposing any steel reinforcement in the process.

We are not talking about lightweight products here but weighty concrete panels, no?

Also if Joe public are on t'uther side of these panels then i would seriously weigh up a more robust method.

What about getting a piece of folded galvanised steel channel and screwing it to the post with screws into rawlplugs at 150mm centres or so.

It would be much less work, much less risk of exposure and therefore corrosion of the rebar, and will also look much better.

Just get a piece of channel with sides about 2mm thick, 25mm deep and wide enough to give a few mm clearance for dropping the concrete panels in.

We are talking about these, but mine has no groove on one side to continue the wall as I had a flat side for gate.

I think that would stand out as you would see the steel on them two posts and none of the rest. As for exposure I will be filling the tops back in with mortor so the post would be back smooth with the slabs in. If you get me.
