Concrete Slab Installation
Concrete slabs planned around use, ground conditions and long-term performance. Shed slabs, garage slabs, patio slabs and general building bases.
- Slabs built around load, ground conditions and intended use.
- Preparation and compaction treated as part of the job, not an afterthought.
- Clear connection between slab services and location-specific pages.
Slabs are built around what they need to support
A slab for a garden shed does not carry the same expectations as a garage slab or a base for a building extension. The difference comes down to load, ground conditions and how the space will be used over time.
This page sits alongside concrete driveways and polished concrete within the broader concrete services structure.
What actually affects slab performance
The condition of the ground, the depth of the base, compaction, reinforcement and how the slab is finished all influence how it performs. A slab poured quickly onto poorly prepared ground is more likely to move or crack.
Preparation is where most problems are avoided
Before concrete is poured, the site may need clearing, excavation and base preparation. Compaction is critical. Without it, the slab can settle unevenly over time.
Formwork, reinforcement and levels are set before the pour. Drainage needs to be planned so water does not collect around the slab.
Cost usually depends on the site
Concrete slab cost factors
Slab cost is influenced by size, thickness, reinforcement, excavation, access and finish. A slab poured on a clean, level site is very different from one that requires significant preparation.
For pricing context, read the concrete cost per m² guide.
