What is included?
Sunken block paving is an area that has dropped below the surrounding surface, often as wheel ruts where cars turn, a dip near a manhole or drain, or a hollow where water sits after rain. The blocks themselves are usually fine; the problem is underneath.
- Investigation of the cause (drain, sub-base, laying course, edging)
- New laying course screeded to the correct level and falls
- Sub-base dug out and rebuilt where it has failed
- Same blocks relaid, re-jointed and compacted
- Blocks lifted, cleaned and stacked for re-use
How we find the cause
- Falls, so water does not collect again
- Replacement blocks or hidden blocks to swap in
- Condition and thickness of your existing blocks
- How much of the area needs lifting to blend the repair
- Whether the edging has moved or was never set in concrete

Sunken paving in Castlereagh: questions
Can you repair block paving in Castlereagh 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.
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.
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.
