Sunken and rutted block paving in Caernarfon: what to expect
Around Caernarfon, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What does a sunken area repair involve?
Common causes are a sub-base that was too thin or not compacted, a laying course that was too thick, water washing sand out through a broken drain, or a trench that was never properly filled. Re-levelling means lifting the blocks in and around the dip, finding and fixing the cause, rebuilding and compacting the layers, and relaying the same blocks so they match.
- Sub-base dug out and rebuilt where it has failed
- Investigation of the cause (drain, sub-base, laying course, edging)
- New laying course screeded to the correct level and falls
- Same blocks relaid, re-jointed and compacted
- Blocks lifted, cleaned and stacked for re-use
How we find the cause
- Whether the edging has moved or was never set in concrete
- Replacement blocks or hidden blocks to swap in
- How much of the area needs lifting to blend the repair
- Condition and thickness of your existing blocks
- Whether a drain or gully is leaking under the paving

Sunken paving in Caernarfon: questions
Why does block paving sink?
Most dips come from a thin or poorly compacted sub-base, too much sand under the blocks, failed edging, or water washing material out from a broken drain.
Can you send someone just to look?
For larger or unclear problems we visit; for small repairs, clear photos with a tape measure in shot are often enough to price it.
Can you repair block paving in Caernarfon without replacing it?
Usually, yes. We lift the affected blocks, fix the bed or base, and re-lay the same blocks so the repair matches.
