Multiple burst drains in an inaccessible five-storey riser — access opened, repaired, made good

The riser was fully enclosed with no access panels, so the leaks could neither be inspected nor repaired.

Water damage across five floors, an inaccessible riser, and a specialist contractor who needed safe access to work.

1. 1Joint survey with Metro Mechanical to locate each failure.
2. 2Formed access openings floor by floor so the drainage specialist could carry out repairs.
3. 3Repaired walls and ceilings and replaced carpets once the pipework was signed off.

• 5 floors — Returned to use
• 1 team — Coordinating access, repair and reinstatement
