Choosing between blocks and a concrete slab
Block Paving vs Concrete for Driveways and Patios
This comparison usually comes down to how you value repairability against monolithic strength. Both perform well; they just behave differently when something goes wrong.
Access to buried services is a factor people rarely consider until they need it.

How each handles movement
Block paving is a flexible system: small units bedded on sand over a compacted base absorb minor ground movement by adjusting slightly. Cracks in the surface are effectively impossible.
Concrete is rigid. When the ground beneath moves, the slab cracks, and that crack is permanent.
Repairs and services
If a water main, gas service or drain under the drive needs attention, blocks lift out and go back with no visible trace. Concrete has to be broken out and the patch will always show.
For any drive with a manhole or a service run beneath it, that is a real advantage.
Appearance and drainage
Blocks offer colours, laying patterns and border courses; concrete offers a plain finish unless brushed, imprinted or overlaid. Permeable block systems also handle front garden drainage rules directly.
Concrete needs falls and gullies designed in.
Frequently asked questions
Does block paving sink?
Only if the sub-base or edge restraints were inadequate — the blocks themselves do not fail.
Which is faster to install?
Concrete placement is quick, but curing time before use is significant. Blocks are usable immediately.
Is block paving suitable for heavy vehicles?
Yes, with the correct block thickness and a sub-base designed for the loading.
