concrete fence posts..securing the panels ?

[ms08]

Wedges....

and would it be an idea to put say a 5mm spacer between the panel and the gravel board so its not sitting in water? couple of stainless washers maybe?

Before you put the panel in you could screw a 4" long bit of thin flat or pre drilled straight bracket in the top of the channel pointing upwards and extending above where the top of the panel will sit, then once you have slid the fence panel in bend the flat over the top edge of fence panel and screw. Easy to remove if you have to change the panel later.

Yep I was going to do the same but ended up with some stainless screws left about 5mm proud, makes a difference allowing the air to circulate underneath.

My brother in law leaves his removable so he can lie them on the lawn and quickly re-paint them using a broom

Could you lie some lengths of wire under the gravel boards (At 90 degrees) when you lay them and drill a small hole in the fence panel near the bottom, pass the wire through the fence panel and twist together. It'll stop someone casually pulling them out, you'll be able to untwist the wire if you need to remove them and you're not drilling into the concrete posts.

Obviously it'll need to be something that's not going to corrode, but some stainless mig wire perhaps or even stiff electrical wire?

I did similar with our trellising to stop people pulling the top section out, but going through the lower fence panels rather than under the gravel boards.

how many did you use?

how many did you use?

One about 50mm from each end and one in the middle to prevent it sagging, 12 years now and all good.

Sticks like ****...that stuff takes a ferocious hold and will set under water...

Spray foam??

I tried wedges BUT the problem with wedges are they pretension (in compression) the top rail, then as they bend in the wind the tension you have created not only helps the panel bend in effect but the wedges then travel further down, causing too much tension because once bent they stay bent,
I if I wanted to remove the panels would make a thin top hat shaped strap out of thin galv , the thin wall plate type straps would do pre drilled etc, then the strap could be put from one panel to the next, screw the strap to the panels only so in effect screwing them all together lift one you are lifting the lot, that then also helps stop them blowing out, if the straps are on the prevailing wind side also stops rattle

I used a bit of strap that goes under the gravel board, up the side of it and over it and then up the fence panel a bit for a screw fixing.

This way you secure the panel but you also help prevent the panel from bowing out in the middle.

If you decide on a method that involves holes into the concrete posts then fill the holes with silicone before driving the screws in, water that's tracked down the screw into the hole and then freezing results in a nice little bit of post cracked out.

The last posts I put up had holes in them too, long screws stop anyone lifting the panels out.

Most annoying thing we had with these fence posts when we had them for the fence between our car park and the canal towpath is that local "characters" would walk past on the way home from the pub and boot them in the centre. They give enough to crack the concrete, and then they're slightly too short to stay in place, as well as looking awful. Council wouldn't allow us to put a proper security fence in, because they were trying to make an attraction out of the area. Should have ignored them after the first time the police visited and told us they wouldn't do anything unless we had clear CCTV footage.

Pieces of builders strap, drill, plastic plug and screw to gravel board, screw to fence panel.

 

[steveo3002]

would it make sense to level the gravel boards with offcuts or whatever then put a dollop of concrete in the slot underneath to stop them sinking /moving as the earth settles?

 

[bigegg]

If that's in their mind(s), there'll be nothing 'random' about their presence.

Or they'll just climb over............

A couple of dozen plant pots with a cane in them "for the plant to climb" make jumping off a 6ft fence *really* uncomfortable.

A length of 4mm galvanised fencing wire run the length of the fence and wire stapled on makes shifting an individual panel difficult, and is relatively unobtrusive
