Sunken and rutted block paving in Carshalton: the local picture
In Carshalton, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Many London streets have controlled parking and narrow frontages, so we measure the car space and the crossover before anything else.

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.
- Sub-base dug out and rebuilt where it has failed
- 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
- Investigation of the cause (drain, sub-base, laying course, edging)
How we find the cause
- What caused the dip or movement: base, laying course, edging or drains
- Trees, roots and past trenches
- How much of the area needs lifting to blend the repair
- Whether a drain or gully is leaking under the paving
- Whether the edging has moved or was never set in concrete
