The Challenge
Storage tanks and containment systems face constant chemical attack, corrosion, and the ever-present risk of a leak that becomes an environmental incident. Tank floors and roofs corrode, linings blister, and concrete bunds crack — and because these assets often hold hazardous product, failure carries regulatory, safety, and reputational cost far beyond the repair itself.
A Real Rumford Example
The Problem
Corroded Potable Water Tank
The internal coating had broken down and the steel beneath was pitted, putting stored potable water and the tank itself at risk.
The Solution
Rebuilt & Fully Relined In Situ
Pitting rebuilt with Belzona 1111 and the tank relined with 5892 — an NSF 61 approved lining for hot potable water, applied in place.

Outcomes vary by component, load, and access — contact Rumford Industrial Group for a project-specific assessment.
Above-ground storage tanks, process vessels, chemical bunds, sumps, and secondary containment corrode from the inside and out. Aggressive chemicals attack linings and base metal, water sits under tank floors, and containment concrete degrades until it can no longer hold a spill.
Belzona provides a complete range of chemical-resistant linings, metal repair composites, and containment coatings applied cold and in situ. From lining a new tank to sealing a leaking floor or waterproofing a cracked bund, Rumford Industrial Group protects containment assets without hot work or replacement.
Belzona Solutions for This Application
Concrete & Structural Restoration
Rapid repair of damaged concrete and steel surfaces across tank internals and secondary containment floors and walls — crack filling, grouting, shimming, infilling, resurfacing, and lightweight vertical repairs that don't require shuttering.
Leak Sealing & Cold Bonding
Fast-curing materials for immediate leak sealing and cold plate bonding — used inside tanks and externally to attach wind breakers, fire deluge systems, brackets, and supports without hot work, plus composite patch wraps engineered to ISO 24817/ASME PCC-2 standards.
Corrosion & Chemical Resistant Coatings
Long-term erosion, corrosion, and chemical resistant coatings and linings for tank internals, externals, and secondary containment — including repair of existing glass flake, rubber, and epoxy linings and specialty coatings such as static-dissipative Belzona 4351.
Tank Base Sealing
Breathable, solvent-free coatings that seal tank bases against water ingress while allowing trapped moisture to escape.

What Belzona Can Do for Tanks & Containment
+
Seal cracks, porous welds, bolted & riveted joints
Seal leak paths through cracks, porous welds, and mechanical joints on tank shells and floors without hot work.
+
Seal seams on floating tank tops
Seal plate seams on floating roofs to stop vapour and product loss and prevent water ingress.
+
Repair & renew damaged linings
Patch or fully reline failed glass flake, rubber, and epoxy linings in situ, without removing the existing system.
+
Waterproof & protect insulation
Waterproof surfaces and protect insulation systems from moisture ingress and corrosion under insulation.
+
Rebuild & protect steelwork
Rebuild corroded and pitted steel back to profile, then coat for long-term corrosion protection.
+
Reform tank supports
Cast a perfect-fit load-bearing surface at tank supports and provide thermal insulation between faces.
+
Secure loose anchor bolts
Re-grout and lock loose or spinning anchor bolts to restore full holding strength.
+
Apply non-skid surfaces
Create durable anti-slip finishes on walkways, stairs, and pedestrian areas around tanks.
+
Repair damaged concrete & restore drainage
Rebuild spalled and eroded concrete and re-profile falls so containment areas drain correctly.
+
Reseat drain covers & gratings
Rapidly re-bed covers and gratings with fast-cure grouts that return to service quickly.
+
Rebuild damaged expansion joint edges
Reform broken-down joint arrises to give sealants a sound, square edge to bond to.
+
Seal expansion & construction joints
Seal movement and construction joints with flexible, chemically resistant materials.
+
Bond & grout chemical resistant tiles
Bed and grout acid-resistant tiles in bunds, trenches, and process floors.
+
Repair & resurface floating tank top seals
Restore worn seal surfaces on floating roofs to maintain an effective vapour seal.
+
Seal & protect containment areas
Coat bunds, sumps, and secondary containment to deliver an impermeable, chemically resistant barrier.
+
Create pre-formed nozzle inserts
Cast dimensionally accurate inserts off-site for fast installation during shutdowns.
+
Protect nozzle internals
Bond pre-formed inserts into nozzles to shield internals from erosion and corrosion.
