Setting a Post for Backyard Gate in Gravel

I'm in the process of replacing a stone patio in my back yard.

As part of this project, I'll be extending a fence and putting in a gate to the back yard to block the space between the house and the existing fence (see picture).

The issue is, next to the house (where I would put a post for the latch of the gate) we have a gravel fill instead of just earth (see photo). The fill goes down to the house footings and weeping tile.

My questions are:

- How would I set the post in the ground given that instead of earth I have gravel?

- Would there be issues with simply attaching a piece of wood to the corner of the house on which that fence latch would be attached? Is there an issue with that?

What you could do is fasten a post to your foundation wall below grade using galvanized threaded rod attached to the house using an epoxy adhesive anchor system. This way the post would match the rest of the fence and the post attached to the house would remain in place. This would be less expensive than digging a 5 foot deep hole and concreting in a post.

Install a 2x6 peice of lumber against the side of the house. That is more than ample for a latch to be installed.

Drill three holes evenly spaced and centered down the board. Have someone help you hold it level against the brick. then mark the location of the holes. Drill into the brick with whatever sized bit is suitable for the lagbolts you have purchased.

Drill through the brick. Fill hole with exterior silicon sealer then insert lags. Add more silicon. Hold up the boards and ratchet in the three bolts.

Your good to go.

Thank you for your response James.

So with only 3 lag bolts, there's no need for concern for affecting the structural integrity of the corner of the house at that level?

Also, for drilling through the brick, as you suggested, I'm worried about cracking the brick while drilling and after putting the lagbolts in.

Should I in fact be drilling between the bricks on the joint lines?

There is no issue with the bricks holding up to the weight. You do have to drill into the middle of the brick, and away from the edges. Not into the mortar joints, they won't hold up. I usually use a 4x4, so that it matchs the rest of the fence. And counter sink the bolts, so that you can't see them and they don't stick out. Either use lag bolts with sleeve anchors or sleeved bolts.

You basically lag bolt it to the house.
