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.
- New laying course screeded to the correct level and falls
- Sub-base dug out and rebuilt where it has failed
- Investigation of the cause (drain, sub-base, laying course, edging)
- Blocks lifted, cleaned and stacked for re-use
- Same blocks relaid, re-jointed and compacted

Sunken paving in Londonderry: questions
Do you cover Limavady, Strabane and Portstewart?
Yes. We cover Londonderry and the places around it, including Limavady, Strabane and Portstewart, and the rest of County Londonderry.
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.
Can you repair block paving in Londonderry 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.
