The issue on this job
The defect was not just a drainage issue; the failed pipe had started to wash material out from below the paving. That meant the repair had to address both the drain and the formation beneath the driveway before the surface could be safely reinstated.
Because spoil storage was tight and the client still needed evening access, the trench had to be opened, repaired, and backfilled on a tight sequence.
How we handled it
We carried out drain excavation in Wimbledon, removed the failed run, rebuilt the bedding, and reinstated the pipe with the correct fall through the crossover zone.
The block paving was lifted in a contained section so the surface could be reset over compacted fill rather than patched back onto disturbed ground.
What the result was
Output
First-visit diagnosis and repair outcome
Delivery
Kept the programme moving
Programme
one day for repair and reinstatement sequencing
The driveway was left with a stable formation and the drainage run was brought back into service without a second visit. The client avoided further settlement at the crossover and had a CCTV-confirmed repair before the paving went back.
If you are dealing with a failed drain section causing voiding beneath block paving on a 1930s semi with front driveway, the next step is a clear scope and quote.
