If you have been researching driveways in Ireland, you have almost certainly encountered both ‘cobblelock’ and ‘block paving’ — sometimes in the same conversation. This guide explains the relationship between the two terms and what to look for when comparing quotes.
Are cobblelock and block paving the same thing?
Yes. ‘Cobblelock’ is the Irish colloquial term for concrete block paving — the same product sold under the brand name ‘Cobblelock’ by Kilsaran Concrete, which became so dominant in the Irish market that the brand name became generic, much like ‘Hoover’ for vacuum cleaners.
When an Irish contractor quotes for ‘cobblelock’, they mean individual concrete paving units — typically 60mm or 80mm thick — laid in a herringbone or basketweave pattern on a compacted hardcore base with a screeded sand bed. This is identical to what UK contractors call ‘block paving’.
| Block type | Price per m² | Typical 50m² drive |
|---|---|---|
| Standard cobblelock (60mm) | €75–110 | €4,500–6,000 |
| Tumbled cobble-effect block | €90–125 | €5,000–6,500 |
| Permeable block paving | €95–130 | €5,200–6,800 |
Cobblelock vs tumbled cobble — a real distinction
While cobblelock and block paving are the same product, there is a meaningful distinction between standard cobblelock and tumbled cobble-effect blocks. Standard cobblelock has sharp, machine-cut edges and a uniform face — it gives a clean, contemporary look. Tumbled blocks have artificially worn edges and a slightly irregular face, giving a softer, more traditional appearance that suits period properties.
Tumbled blocks cost €10–20/m² more than standard cobblelock and take slightly longer to lay because the irregular edges require more care in setting out.
What to check when comparing cobblelock quotes
A proper cobblelock driveway quote should specify: excavation depth (minimum 200–250mm for a car driveway), base material (Clause 804 hardcore, minimum 150mm compacted), sand bed depth (30–40mm screeded sharp sand), block thickness (60mm for cars), edge restraints (concrete haunching on all free edges), and jointing sand (kiln-dried, vibrated in).
If a quote simply says ‘cobblelock driveway, €X’ without these details, you cannot compare it meaningfully with a properly specified quote.
