Brackets for fence?

[JeRo]

Spring is approaching and I'm thinking about a fence, but the question is how to best secure the fence posts. The fence will be around 80 cm high.

The best option is probably cast concrete foundations, but I'm wondering if any of my ideas are a good alternative:

A) Metal spike in the ground, about 70 cm deep, and then a post measuring 95x95 mm.

B) Fasten post holders (how?) to the existing wall and the post measuring 95x95 mm therein.

Grateful for answers.

What does the wall look like and what type of ground is it? 90-stakes sound like overkill.

If you have an existing wall that is strong enough to attach the posts, it is easiest to use it, simply bolt it on, or alternatively drill and cast post bases, they come in a variety of models, google it.

Overkill is at least better than the opposite

The wall is a retaining wall of this model http://www.byggmax.com/se-sv/prod/pid-02650
The ground is fairly compacted but about 40 cm of topsoil that has been lying for two years on top.

If the wall blocks are just loosely stacked on each other, there is probably nothing to attach a fence to.

Otherwise, it would be convenient if you could drive down spikes and get stability in it, but 80cm is not very high. Personally, I would choose 70 posts for aesthetic and economic reasons. 90 posts are usually used for fences or pergolas and other higher constructions.

If javelins with 70-posts are enough, I would be super satisfied, but are they?
How big is the risk that it will turn into a mess when there is topsoil on top and when the frost comes?

The problem with the spjuten is usually that you can't get them into the ground properly due to stones. I've never heard of anyone having issues with frost and these spjut, but if anyone else knows something, he/she can give a shout.

My experience is that I have fairly stone-free soil, knock on wood...
It seems like spears are quite a good idea, I’ll let it all germinate in my head until spring is truly here... Thanks for the feedback.
