ᐅ Fence Construction – Installing Posts on an Uneven Sandstone Wall?

Changeling schrieb:

A good idea! But up to what height would this work? The panels are 2.50m (8 feet 2 inches) long and 1m (3 feet 3 inches) high. The sandstone shows differences of more than 5cm (2 inches) along the entire length, so in the worst case, such a "mortar base" can become quite high.

Why are you only considering the appearance of the base itself?
What really matters is how the entire fence looks afterward. It should be straight horizontally. Also, it shouldn’t look like a snake shape from the side. For that, it is important that all the bases are at the same height and aligned laterally.
And one more thing:
It doesn’t help to make the base or the whole post lower than the highest point of the wall – unless you want to shorten all your wire mesh panels?

It doesn’t help to set the post base deeper than the highest point of the wall—unless you want to cut all your welded wire panels shorter, right?

But as soon as you cut the posts, that’s where corrosion will start. Or if there’s a small scratch on the powder coating... and so on.
If you haven’t bought anything yet, go for stainless steel, grade V2A or V4A. The higher cost is offset by practically unlimited durability.

Hmm... this seems more complicated than I initially thought.

Would it be an option to sacrifice 20cm (8 inches) of space and cast the fence directly behind the wall or attach it right to the wall with concrete? Something like this, viewed from above:

The posts marked in red would be placed almost leaning against the wall and then encased with a semicircular concrete surround. The soil behind would need to be well compacted to prevent the fence and concrete from toppling over. Would that work?

The advantage would be cheaper posts (no freestanding base plate) and less complex leveling.
Or would it just look very awkward?

Hello changeling

That is probably the simplest solution.
However, I would leave a few centimeters of space between the wall and the fence. About 10cm (4 inches), drill holes or dig out the ground. Make the posts a bit longer. Align them plumb and set them in concrete. You plan to plant a hedge along the fence anyway.

In that case, I would still leave a few centimeters of space next to the wall.

What’s the reason behind this? I want to minimize wasted space as much as possible, even though there will be a hedge there (which shouldn’t grow directly under the fence).

What is the background?

Hello Changeling,

dirt will collect between the wall and the fence, as well as moss and plants.
With a gap of 10cm (4 inches), you can pull it out from the street side. If you work directly at the wall, you will need pliers and tweezers.

Alternatively, with slightly more material usage:

According to the method described in post #2, align crossbeams horizontally along the entire length on each side, and then mount the posts on them.
