Sunken and rutted block paving in Harpenden: what to expect
Homes in Harpenden include plenty of semis and detached houses with room for a drive, plus older terraces where parking is tighter.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

What you get with our sunken paving service
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.
- Investigation of the cause (drain, sub-base, laying course, edging)
- New laying course screeded to the correct level and falls
- Blocks lifted, cleaned and stacked for re-use
- Same blocks relaid, re-jointed and compacted
- Sub-base dug out and rebuilt where it has failed
Before we price your sunken area repair
- Replacement blocks or hidden blocks to swap in
- Whether the edging has moved or was never set in concrete
- What caused the dip or movement: base, laying course, edging or drains
- Whether a drain or gully is leaking under the paving
- Trees, roots and past trenches

Sunken paving in Harpenden: questions
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 Harpenden 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.
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.
