“Crown corrosion was at 60% wall loss in the worst segment — we were heading toward emergency replacement. LiningWorks specified a structural liner rated independent of the host pipe and installed it through cleanouts without excavation. Full structural rehabilitation without shutting down the facility.”
PROBLEM SIGN · COMMERCIAL TRENCHLESS REPAIR
Structural corrosion and erosion are progressive wall-loss failures that worsen with every flow cycle.
Hydrogen sulfide corrosion in sanitary sewer pipe and abrasion erosion in stormwater systems reduce pipe wall thickness progressively — decreasing structural capacity with every flow cycle. CCTV camera inspection quantifies the degree of material loss and determines whether CIPP lining can restore structural integrity before complete failure.

HOW CORROSION AND EROSION FAIL PIPES
The two main structural deterioration mechanisms in commercial pipe systems.
Structural deterioration through corrosion and erosion follows predictable patterns — both are progressive, both are accelerated by specific operating conditions, and both are addressable by trenchless rehabilitation before they reach failure.
H2S corrosion — hydrogen sulfide attacks concrete and clay crown zones
Abrasion erosion — high-velocity flow carries abrasive sediment through stormwater pipe
Electrochemical corrosion in metallic pipe — CMP and cast iron deterioration
Combined corrosion and erosion in high-sulfide gravity sewer systems
THE REHABILITATION WINDOW
When corrosion-damaged pipe can still be rehabilitated — and when it can't.
Corrosion and erosion damage can be rehabilitated with CIPP lining as long as sufficient structural integrity remains to support liner installation. Once pipe wall loss reaches critical levels, excavation becomes necessary.
- CIPP lining is viable when sufficient host pipe geometry remainsCIPP lining requires sufficient remaining pipe structure to define the liner profile during installation. Moderate corrosion — even with significant wall loss — is typically still CIPP-viable if the pipe geometry is intact.
- Structural CIPP liners are designed to operate independent of the host pipeHeavy-wall structural CIPP liners are specified to carry full design loading independent of any remaining structural contribution from the host pipe — providing complete rehabilitation in heavily corroded systems.
- Corrosion-resistant CIPP materials protect against renewed corrosion attackCIPP liners are chemically inert to hydrogen sulfide and sulfuric acid — providing a corrosion-resistant interior surface that prevents renewed attack after installation.
SYSTEMS MOST AT RISK
Commercial pipe systems with the highest corrosion and erosion exposure.
Corrosion and erosion risk is highest in specific operating environments — particularly systems with sulfide-generating conditions, high-velocity stormwater, or metallic pipe in aggressive soil.
Gravity sewer mains with long hydraulic residence times
Stormwater pipes with steep gradients carrying abrasive sediment
Old CMP culverts and storm drains in corrosive soil environments
Commercial kitchen and process drain systems with chemical discharge
BEFORE & AFTER
Food processing facility — severe H2S crown corrosion rehabilitated without excavation.
A Charlotte food processing facility's gravity drain system had developed severe crown corrosion in a 200-foot concrete drain main — camera inspection showed crown material loss of approximately 60% over the most affected segment, with active corrosion visible throughout the run.
LiningWorks specified a structural CIPP liner rated to carry full loading independent of the host pipe — accounting for the measured wall loss at the crown. Installation was completed through existing cleanout access with the facility maintaining partial operation throughout. Post-installation camera confirmed full liner bond and complete coverage of all corrosion zones.

WHY LININGWORKS
How LiningWorks addresses structural corrosion and erosion in commercial pipe.
Corrosion and erosion rehabilitation requires accurate measurement of remaining wall thickness before liner specification. LiningWorks camera-first assessment determines CIPP viability and specifies liner thickness based on actual pipe conditions.
CCTV assessment quantifies wall loss for accurate liner specification
Structural CIPP liners rated independent of the host pipe
CIPP materials are chemically resistant to H2S and sulfuric acid
Installation through existing access points — no excavation
HOW TO GET STARTED
Get corrosion and erosion rehabilitation started in three steps.
Camera assessment measures wall loss and confirms CIPP viability before the rehabilitation window closes.
