Excavation of a collapsed drain pipe by professional drainage engineers

Collapsed Drain Under Conservatory

Conservatories are frequently built over existing drain runs, and the added weight and foundation work can damage ageing pipes. A collapsed drain under a conservatory causes damp, bad smells, and can undermine the conservatory's foundations.

What to Look For

  • Damp or musty smell in the conservatory
  • Condensation problems beyond normal levels
  • Cracks in the conservatory base or dwarf walls
  • Wet patches on the conservatory floor
  • Drainage problems coinciding with conservatory construction
  • Soft ground or subsidence around conservatory edges

How We Diagnose the Problem

CCTV surveys from external manholes inspect the drain beneath the conservatory. We trace the pipe route to confirm its exact position and assess the type and extent of collapse.

How We Fix It

No-dig relining is the preferred method as it avoids disturbing the conservatory. The liner is inserted from external access points and cured in place. If excavation is unavoidable, we work through the floor with protective measures and reinstate all surfaces.
