Split Logs & Walling
Sandstone Logs Sydney
Sandstone logs are Sydney’s honest retaining wall: solid stone, laid in courses, that will outlast every timber sleeper wall in the street. Our split logs are quarried at Glenorie at approximately 300x300mm in cross-section — sawn top and bottom for stable, level coursing while keeping a natural rough split face for character.
They’re a great alternative to the massive traditional sandstone logs of old: the 300x300mm format installs with small machinery, suits tight-access suburban sites, and delivers the same solid-stone permanence at a friendlier scale and price.
What Makes a Split Log
Each log is split from quarry stone, then sawn on its top and bottom beds. The sawn beds are the practical magic — courses stack level and tight without packing, which makes walls faster to build and structurally predictable. The exposed face stays rough-split, so the finished wall reads as natural stone rather than machined product.
At roughly 300x300mm and various lengths, logs weigh in at a couple of hundred kilograms per metre — enough mass to work as gravity retaining, small enough for a mini-excavator or kanga to place. Where space is tight or a more structured look than boulders is wanted, split logs are the answer.
Logs vs Timber Sleepers vs Concrete
Treated pine sleeper walls last 15–20 years before rot and termites win; concrete sleepers last longer but always look like concrete. Sandstone logs are stone through and through — no rot, no rust, no fading, and they look better at year thirty than year one as the face weathers. Joint drainage is natural, so hydrostatic pressure issues that plague solid walls are reduced.
On price, timber is cheapest upfront, but stone wins the moment you factor a single rebuild — and it adds value timber never will.
Beyond Retaining: Steps, Edges and Seats
The 300x300mm module is a ready-made garden step — one log per rise, sawn beds up and down. Single courses make substantial garden edging with real presence; doubled up, they’re informal seating walls around fire pits and lawns. One product, most of a landscape plan.

Frequently Asked Questions
What size are sandstone logs?
Our split logs are approximately 300x300mm in cross-section in various lengths — sawn top and bottom for stable coursing, with a natural rough split face. Larger blocks and boulders are available where more mass is needed.
How much do sandstone logs cost in Sydney?
Split logs are quoted per job based on quantity and delivery — send your wall length and height for a free quote. As a guide, stone logs cost more than treated pine upfront but never need replacing.
Are sandstone logs better than timber sleepers?
For longevity, unquestionably — stone doesn’t rot, warp or feed termites, while treated pine walls typically last 15–20 years. Sandstone logs also drain naturally through their joints and improve with weathering.
What machinery do I need to install sandstone logs?
Small machinery is enough — a mini-excavator, kanga or skid steer places 300x300mm logs comfortably. That’s the point of the format: solid stone retaining for tight-access suburban sites.
How high can I build with sandstone logs?
Single-skin log walls typically go to about 1 metre without engineering. Above that, most NSW councils require approval and an engineer’s design — tier the wall or step up to larger blocks for taller retaining.
