Flagstone Concrete Sleeper

Overview

Flagstone uses an irregular crazy-paving face in mixed light stone colours. It is the most decorative of the set and suits garden walls that are meant to be seen, not a long side boundary under a fence.

What the design looks like

Bone and latte flagstone. Surface: Irregular stone paving. Finish: Flagstone / crazy paving.

Typical applications

Garden feature walls
Stepped landscaping
Short street-front batters

Beside a fence

The face does not hold the soil – the posts, the sleepers as a stack, the drainage and the footing do. A Flagstone wall can sit under a new Colorbond fence or a timber fence. The fence posts and the retaining posts are planned together so the finished ground level and the fence height still make sense. More on that on the under-fence section.

Standalone walls

The same sleeper is used for garden and driveway walls that do not carry a fence. Those walls still need the right posts, drainage and – where height, soil or surcharge require it – an engineer. We do not guess a maximum height from the face design.

Installation and drainage

Best on the public face of a short or stepped wall.
A plain fence above it keeps the wall as the feature.

Water behind a retaining wall is a load. We plan drainage with the wall – not as an afterthought – so water can leave instead of sitting against the sleepers. The exact arrangement depends on the site.

Advantages

Garden character
Light colours sit with cream brick

Things to consider

Too busy for a long side boundary
Batch colour will not be identical to a photo

Maintenance

Concrete sleepers do not need oiling or painting. Wash them if they pick up dirt. Do not pile extra soil against a fence above the wall, and keep drainage outlets clear.

Common questions

Can a Flagstone sleeper sit under a Colorbond fence?

Yes. The sleeper face does not change how the wall and fence are set out. Posts, drainage and finished ground level still have to suit the site. See walls under fences.

Can I use it as a standalone garden wall?

Yes. Standalone walls use the same sleepers and steel posts. Height, soil and anything sitting above the wall (a driveway, a path, a building) decide whether the wall needs an engineer. We will tell you on the site visit.

Do you publish a price for this sleeper?

No. The board is only one part of the wall. Posts, excavation, drainage, access and whether a fence sits on top all change the job. We quote after a free measure.

Are the sizes fixed?

Colour names differ between makers. We specify the face, then confirm the batch on the quote.
