Garden wall - concrete block type

[heliart]

Hi there,

So I've done quite a bit of block work before.
Built a single storey workshop with cavity wall etc, and been through the building control process, so not an issue with technique.

Where I would like some advice is that I'm replacing a section of garden fence with a 6ft wall. This is a non retaining wall. It's about a 15M run. My plan is to constructed from 100mm wide dense concrete block, with pillars every 3 meters.

Is this the best construction method, or would I be better off with hollow blocks (concrete filled) or wider blocks and reduce the pillar count?

Cheers all,

Steve

youre not bothered about the appearance then????.

I always prefer a 225mm wall myself and do away with piers.i would always use bricks but as its blocks on the spec,i would lay them flat as i prefer this look to them layed in a conventional way.

you will gerts lots of varying ideas and options.

Appearance, yea a little, but here's the reason.
It's right at the bottom of the garden - from my side, there's going to be a shed in front, and I intend to continue the wooden fence up to the shed (gladding if it has to go over the wall) just so it looks nice.
The neighbours side is basically a large composting/dump area - I was intending to continue the fence, but the previous fence rotted to nothing, so I figured the wall would make a better barrier.

Like I said, it's 15M long, 1.8M tall.

Avoiding piers is my preference. There's a 12M run to a corner, then a 3M run. From what I understand as guidance, a 2M high wall needs 300mm wide blocks.

i would be erring on the side of caution, thats a long length of wall to fall in a high wind.

allow for expansion joints too.
