The Best Base for Your Garden Shed
When it comes to bases for garden sheds, there are several options — timber bearers, pavers, compacted gravel and concrete slabs. While each option has its advocates, a properly poured concrete slab is far and away the most durable, pest-resistant and long-lasting choice for most Australian homeowners.
Why Not Timber Bearers?
Timber bearers were the traditional choice for shed bases, but they come with significant drawbacks. Even treated timber will eventually rot in Queensland's humid climate — often within 10–15 years. Timber provides ideal conditions for termites and other pests. The shed floor also tends to be uneven and prone to warping. Replacing rotten bearers is a significant cost that concrete simply doesn't have.
Why Not Pavers?
Pavers can work as a temporary or decorative solution, but they're not ideal for shed bases. They shift over time, leaving gaps. Weeds and grass grow between them. They're not level or stable enough for heavier sheds or machinery. And they don't provide a sealed surface that keeps moisture and pests out.
Benefits of a Concrete Shed Slab
- Lasts decades — A properly poured concrete slab will outlast the shed itself
- Termite-proof — Concrete provides no food or harbour for termites
- Level and stable — A flat, solid base means no movement, no warping, no shifting
- Easy to clean — Smooth concrete is simple to sweep and hose down
- Keeps moisture out — A good slab with edge beams keeps ground moisture from entering the shed
- Can be colour sealed — Add a colour seal to protect and improve the look
What Size Slab Do I Need?
The slab should be the same size as the shed's base or slightly larger. We recommend a 75–100mm thick slab for standard garden sheds, and 100mm+ for heavier structures or those housing machinery and vehicles.
