Trunk main infiltration sealed under live flow

Scope of work

The challenge

Persistent inflow and infiltration was overloading the municipal treatment system during wet-weather events. Conventional dig-and-replace would have closed a major arterial road for weeks. The municipality needed the leaks stopped fast, with proof of result.

Our approach

• CCTV survey to locate and rank every active defect.
• Hydrophobic polyurethane injected at each joint under pressure.
• Live verification pass confirming each seal before moving on.
• Final CCTV footage and a defect-by-defect completion report.

“They stopped the water without closing the road. We had the report in hand the same week.”
