Definition
Interlocking paving is precast concrete blocks in interlocking shapes laid on a sand bed over a compacted base without mortar, with sand-filled joints. Common thicknesses are 6 cm for paths and 8 cm for parking and roads.
Why it matters on a project
Quick to lay, easy to lift for repairs, and it lets some water drain. Base quality and compaction decide whether it stays level or settles.
Measurement and pricing
Per square metre including sand bed and laying, kerbs per linear metre, and the aggregate base usually separate.
Common mistake
Laying on uncompacted ground without kerbs to restrain it, so it shifts and sinks under cars.
Frequently asked questions
What thickness for parking?
Usually 8 cm for parking and car traffic, 6 cm for footpaths.
Why are kerbs needed?
To restrain the blocks at the edges and stop them shifting apart.
