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
- Same blocks relaid, re-jointed and compacted
- Blocks lifted, cleaned and stacked for re-use
- 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
- Trees, roots and past trenches
- Whether the edging has moved or was never set in concrete
- Condition and thickness of your existing blocks
- What caused the dip or movement: base, laying course, edging or drains
