Stop leaks and lost product safely — often without requiring a shutdown.
Fast-cure composites that seal leaking pipes, flanges, tanks, and fittings in situ (while in service).
Works effectively on wet, oily, or contaminated surfaces.
Minimizes downtime by allowing repairs often with no shutdown required.
The Challenge
A leak rarely happens at a convenient time. Whether it is a weeping flange, a pinhole in a pipe wall, or a corroded tank seam, the pressure to stop the loss fast is immediate — every hour of lost product, environmental risk, and safety exposure adds cost. Traditional responses like welding or replacement often require isolation, draining, and hot-work permits that turn a small leak into a major shutdown.
Pipe leak repair with Belzona epoxy composites.
Leaks develop across pipework, flange faces, valve bodies, storage tanks, and process equipment throughout every industry — driven by corrosion, erosion, vibration, thermal cycling, and gasket failure. When a component is live, wet, or holds residual product, conventional repair simply is not an option without a full outage.
Belzona's cold-applied composite systems are engineered to seal and rebuild leaking equipment in situ — including live-leak sealing techniques that stop the flow before a permanent repair is built up. Rumford Industrial Group brings this capability, and the on-site expertise to apply it safely, to facilities across five states with 24-hour support.

What We Seal & Repair
Pipes & PipeworkSeal pinholes, through-wall corrosion, and split seams, then rebuild lost wall thickness with a reinforced composite wrap.
Flanges & JointsStop weeping flange faces and re-establish a leak-tight seal without breaking the joint or replacing gaskets.
Valves & FittingsEncapsulate leaking valve bodies, bonnets, and fittings to contain product and restore integrity.
Tanks & VesselsRepair leaking tank shells, floors, and nozzles — sealing active leaks and lining against further attack.
Heat ExchangersAddress leaking tube sheets, channel heads, and water boxes without cutting out and re-welding components.
Concrete & ContainmentSeal cracked bunds, sumps, and secondary containment to stop ingress and contain process fluids.
Belzona Solutions for This Challenge
Emergency Fast-Cure Repair
Rapid-curing composites that stop leaks and return equipment to service quickly — even on wet, oily, or contaminated surfaces where preparation is limited.
Live-Leak Sealing
Techniques and materials designed to seal active, pressurised leaks in place — arresting the flow so a permanent composite repair can be built up.
Pipe Wrap & Reinforcement
Reinforced composite wrap systems that rebuild lost wall thickness and restore pressure integrity to corroded and damaged pipework.
Metal Repair & Rebuilding
High-strength, machinable composites that rebuild leaking or eroded metal components back to original dimensions without hot work.
High Temperature Repair
Repair systems rated for elevated operating temperatures where standard epoxy products would soften — for hot process lines and equipment.
Protective Overcoating
Corrosion-resistant coatings applied over the repair to prevent recurrence and extend the interval to next maintenance.
How It Works
01
Assess & ContainThe leak source, operating conditions, and substrate are assessed to select the right technique — from live-leak sealing to a full composite rebuild. Safety and containment come first.
02
Surface PreparationThe area is cleaned and profiled as far as conditions allow. Belzona systems are formulated to bond even on damp, oily, or difficult surfaces where standard products fail.
03
Stop the LeakFast-cure materials are applied to arrest the active leak. Reinforcing tapes and composite wraps build strength around the defect where structural repair is needed.
04
Rebuild & ReinforceLost wall thickness and damaged sections are rebuilt to restore mechanical integrity — no welding, no hot work, no distortion of the parent component.
05
Protect & Return to ServiceAn optional protective coating guards against recurrence, and the equipment is returned to service in hours rather than days.
