I will be installing a 5ft high double wooden gate with two 1m panels.

The gate panels are well made so pretty weighty and I plan to fix them to 4x4 wooden posts.

One post will be fixed to a house wall so fairly straight forward.

The other post will be fixed to or through a concrete floor and I don't know how thick the concrete is.

Rather than creating a hole through the concrete for setting the post in I was thinking about using a bolt down post holder as an alternative?

I am slightly nervous about this method but has anyone tried this method before with gate posts?

Your opinions would be most welcome.

you are describing a long lever, used for wrenching bolts out of concrete

short answer: won't work.

Gateposts carry tremendous forces

Presumably your gate is against a fence or something. There is a way of bracing the top of the gatepost to the bottom of the next fencepost along, or the wall or whatever. Or putting a lintel between the tops of the two gateposts.

Tell us more about your installation.

I use bolt down post holders without any issues for the past 5yrs........just make sure you use pretty good long anchor bolts and also fill with resin too. Nobody be pulling them out in a hurry

That will depend entirely on the strength and thickness of the concrete.

is it possible to add a brace at 45 degrees (other angles are available) to at least one side of the gate post?
Could be timber or a bit of scaff pole using adjustable angle KeyKlamps
 
Thanks for you comments.

If I was to use a bolt down holder I would look use M10x75mm masonry fixings like these:

I guess it is down to the thickness of the concrete so will drill a pilot hole.

Fixing the post in with a hole and then postcrete fills me with a bit more confidence as the first post by JohnD rings true, the gate is affectively a long lever.

However, if the concrete was really think and the fixings are also chemfixed as jowwy says then they would be solid.

I have read though that sometimes you can get play in postcreted posts.
 
play in postcreted posts is likely to be bad hole digging.
Digging a deep but relatively narrow hole and not disturbing the compacted soil is very important
 
I have a set of wide gates, 3.2m, (no centre post) but wouldn't entertain a bolt down post. Although the width of yours is slightly smaller, you really want to be digging a hole and sinking in a decent post, the longer the better.

I bought 3m posts (150mm sq) and have 2m out the ground.

One thing I hadn't accounted for was how much the wind rattles the gates, so much so, that a few dome head screws have sheared the heads off, from the bolt locks that go into the ground.

Good luck
 
Thanks.

Anyone know how long you should leave postcrete to cure before handing gates?

I know it goes hard after 10 mins but should I leave it 2-3 hours?
