Fence posts in new concrete patio
 
I'm putting a new 4" slab in for a back patio.

1. runs up to the driveway
2. there is a 17' fence + gate between garage and house to replace.
3. i'm looking for ways to NOT set the new posts in concrete.

Is there a way to mount them in packed gravel? I've read about people doing this and want to consider something like setting large PVC in the ground/concrete and packing the posts in the pipe with gravel?

The fence is about 4.5'. There are 4 posts. Each end post and one post flanking the gate.

Thanks folks.

galvanized chain link?
do you have a post hole digger?

I want to keep it wood. I have a post hole digger, not a problem.

Is concrete really necessary? Especially if I set them 24 to 36" down?

Why not concrete?
If there's a gate post then it would be far better to at least have that and the latch side in concrete.

Nope, not in the least...

"2. there is a 17' fence + gate between garage and house to replace."
I'm assuming the gate isn't 17' long? If so, should be no problem to put a wood post in the ground to hold a gate up without concrete.

The problem is the location of the posts are going to sitting in the edge of the new slab.

I was wondering if I could put large pipes (10+ ") in the ground and pack the posts in gravel/sand and then pour the new slab do the top of the slab is at the op of the pipes.

Yeah, I'd have some round gravel bases showing at the posts but I don't want to make the posts permanent for the next owner. This way, the posts could come out to be changed some day without destroying the new slab.

I didn't pick the location, it's just where the fence runs between my garage and house.

No, a 4' gate, not all 17'. :)


If my description sucks I'll tag an image.

like SONOTUBE and pack the posts in gravel/sand and then pour the new slab do the top of the slab is at the op of the pipes... then cut the tube some.

works for me

Agreed.

Dornier 01-12-2012 07:04 PM

That sounds good. I've seen those--didnt connect.

Question: I am thinking now the tubes would be too close to the driveway.

Cut them in half? I suppose existing earth would provide strength on that 1/2 of the post.

Why not setting metal post bases on the concrete (the ones made for fences) and the posts on the post bases?

Dornier 01-13-2012 05:15 AM

I'd need to pour thicker there, and I worry about their strength. The based are tough, but it's still only holding about 6 inches of wood.

The E-Z Base is what I looked at.

This is what working with.

The patio is a good height to the back door but I suppose I could put a small step there if needed.

It slopes down toward me taking the photo, but the driveway slopes away from me here.

There are two posts that I pulled out due to rot. The others will be replaced where they are.

Just wondering how the "double slope" would affect sinking those posts with gravel and sand.

Thanks again.
