Building a non-retaining garden wall.

[shackleton09]

Hello,
I'm planning to build a wall in my garden. The wall is to sit on an existing concrete base that is edged by 4 courses of bricks that are in turn sitting on 4 inch footings.
The planned wall is to be built of 9 inch hollow blocks to a height of 1.5m in a 3 sided form. The blocks will sit half on the bricks and half on the concrete section.
Is this practical and is it ok to use hollow blocks?

I would recommend a minimum of 150-200mm concrete footing for this type of wall, depending on the sub soil, laid at correct depth.

That is not to say what you have is not adequate but other factors may influence whether what is there is adequate, i.e. soil conditions, water run off, wind and frost exposure etc.

Hi noseall,
Many thanks for the advice.
I feel more confident to continue bearing in mind what you say.
