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
In sanitary sewer pipe, hydrogen sulfide gas converts to sulfuric acid at the pipe crown — dissolving the calcium carbonate in concrete and clay. The corrosion zone extends from the waterline upward, with maximum attack at the crown.
Stormwater systems carrying sand, gravel, and debris at high velocity experience progressive abrasion erosion at the pipe invert — reducing wall thickness most severely at the 6 o'clock position.
Electrochemical corrosion in metallic pipe — CMP and cast iron deterioration
Corrugated metal and cast iron pipe corrode electrochemically in aggressive soil and groundwater environments — reducing wall thickness uniformly or at concentrated corrosion cell locations.
Combined corrosion and erosion in high-sulfide gravity sewer systems
In gravity sewer mains with long residence times and sulfide-generating conditions, crown corrosion and invert erosion can occur simultaneously — doubling the rate of structural capacity reduction.
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 remains
CIPP 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 pipe
Heavy-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 attack
CIPP liners are chemically inert to hydrogen sulfide and sulfuric acid — providing a corrosion-resistant interior surface that prevents renewed attack after installation.
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
Gravity sewer systems with flat gradients and long hydraulic residence times generate anaerobic conditions that produce hydrogen sulfide — creating the most aggressive corrosion environments for concrete and clay pipe.
Stormwater pipes with steep gradients carrying abrasive sediment
Stormwater systems with steep grades carrying sand and gravel during peak flow events experience the most aggressive invert erosion — particularly in concrete and CMP systems receiving runoff from unpaved surfaces.
Old CMP culverts and storm drains in corrosive soil environments
CMP culverts in acidic or high-chloride soil environments corrode at accelerated rates — often showing significant wall thinning before any surface indication of deterioration is visible.
Commercial kitchen and process drain systems with chemical discharge
Commercial kitchen and light industrial process drain systems handle chemical discharges that accelerate corrosion in metallic pipe — cast iron building drain systems are particularly vulnerable.
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.

We had a plumbing emergency around the holiday's and called a local plumbing company. They cleared the line and quoted a pretty high price to dig up my yard and fix the damaged sewer line. The next day I found LiningWorks online and called Jeremiah. He was very helpful and confident they could fix my sewer line without digging. Seemed too good to be true. The lining has been installed, yard not damaged and looks to have resolved the break. Jeremiah even offered to come back and scope it at a later time to ensure it's all good. Highly recommend Lining Works for any situation where you can't or don't want to dig. Thanks guys!

LiningWorks was top notch. We had a sewer main that got damaged and was completely blocked up. They were able to clear the drain, remove all issues, and reline the entire sewer main without cutting out my driveway and yard. And they were able to get the job done in one day. I would and plan to do business these guys again in the future and would highly recommend them to others.

Where do I begin? Let's just say I had an absolute nightmare on my hands for about 5 years with my sewage. I had one company quote me 7k after he snaked my sewage line and from there I just kept snaking it every year. I dreaded the oncoming financial disaster but I bit the bullet and called LiningWorks. BEST home decision of 5 years. Jeremiah came out and tackled this chaos with grace and integrity. He got down to the root of it — after years of money, anxiety, and frustration he found out it was a city problem! I will definitely be calling LiningWorks when my lining needs replacing. Call them now, you will not be disappointed.

I am very happy with the work that was done and the clean up after the job was done. Jeremiah and Ralph are very professional and skilled in their craft. I received an estimate and the job did exceed the original estimate. I contacted them about it and they were very understanding and explained why.

Lining Works was excellent to work with. They were perfectly professional. They were organized, efficient, and friendly throughout the whole process. They took time to answer all of our questions. Pipe lining is an incredible option and the team at Lining Works couldn't have been better. They were also transparent, honest, and consistent with their cost/pricing. We couldn't be happier. We feel very fortunate that we found Lining Works. Great guys!

The main drain line in our airbnb kept clogging up, filling the house with an awful sewage smell. We had drain cleaners come out to clear the line every couple months but it finally got so bad we had to close off our bookings. LiningWorks were very prompt in coming out. We discovered tree roots had broken up our line. Our sewage line runs under a tree and 6ft deep through our crawlspace so digging it up was going to be a nightmare. Liningworks was able to cut the tree roots out and line the pipe without any digging so that it's as good as new. Would definitely recommend them to anyone needing sewage line repair.

Lining Works responded to my request quickly and fixed my drain problem very fast. I would highly recommend you give them a call.
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
Camera inspection documents corrosion and erosion severity across the full affected run — providing the wall-loss data needed to specify liner thickness for structural sufficiency.
Structural CIPP liners rated independent of the host pipe
Heavy-wall structural liners are specified for heavily corroded systems — designed to carry full design loading without any structural contribution from the deteriorated host pipe.
CIPP materials are chemically resistant to H2S and sulfuric acid
CIPP liner resins are formulated to resist hydrogen sulfide and sulfuric acid attack — providing a permanently corrosion-resistant interior surface after rehabilitation.
Installation through existing access points — no excavation
CIPP lining in corrosion-damaged systems is performed through existing manholes and cleanouts — no excavation, no facility shutdown for excavation access.
