Can you post some pics to help with the explanation and is the wall perpendicular to the slope or parallel to it?
Hi everyone
I was hoping to get some advice on installing a small garden wall (one course + capping stone) around an existing garden bed.
I am using the Adbri Masonry imitation blocks (300mm x150mm x220mm) that stack together (already purchased).
The question I have is about the site itself. I want to lay them in a location where there is an existing small slope – about 10cm fall over 7 metres.
The instructions state that the base of the wall should be level before laying.
I would much prefer to lay the blocks keeping the gradual existing fall and not modifying it as I want the wall to run alongside some stepping stone pavers that keep to the gradual existing fall
Is there a fundamental flaw in keeping the fall and not making it level? I understand that it would be an issue if the fall was significant but 10cm over 7 metres wouldn’t classify as significant would it?
Any advice would be much appreciated.
Cheers
Matt

The majority of the wall - shown red in the attached picture - follows the fall on the slope but the slope is only about 10 cm fall over 7m
Go for it. If you don't like it, you can always rip it up and redo it, but I don't think it will cause any trouble. You should however ensure that whatever you're laying the bricks on, is smooth, rather than necessarily level, so that the bricks lie evenly. You may need to lay a sand or sand / cement bed first.

In my not so humble opinion, you have two issues with your garden bed and proposed retaining wall.
The trees are far too close to the house. They look pretty now as small shrubs, but in a few years' time when they start to put on some size they will suck the moisture out of the soil, potentially cause cracking of the footings and the wall, drop leaves into the guttering...the list goes on. From personal experience, it's a costly fix.
The other issue is that you have sub-floor vents in the brick footings. It's not a good idea to cover these. And if the soil goes above the damp proof course, you're leaviing yourself open to rising damp.
Good luck though.
