Service Type Emergency Leak Repair

Response Window Same-Day Urgent Call-Out

Final Outcome 100% Leak Cleared & Tested

The Initial Emergency

The client contacted our 24/7 team reporting a critical loss of water volume alongside clear indications of an underground main supply rupture beneath the structure. With water supply infrastructure compromised, prompt dispatch was required to curb foundation dampness and prevent irreversible sub-floor damage.

Works Executed On-Site

Pinpoint Acoustic Detection

Non-invasive tracing tools were used to locate the precise coordinates of the subsurface water leak, eliminating unnecessary destructive works across the entire floor run.

Targeted Sub-Floor Excavation

Carefully excavated the identified section of the flooring down to the incoming water main without damaging peripheral building cables or adjacent foundation components.

Pipe Section Extraction & Replacement

Extracted the corroded, split piping segment and installed high-grade, commercial-standard pipework coupled with a new heavy-duty inline isolation valve for future accessibility.

High-Pressure Diagnostics & Site Re-securing

Conducted extensive hydraulic pressure checks to verify zero pressure loss throughout the line. Cleaned and stabilized the excavated floor area ready for finish contractors.
