Protecting Manholes from Infiltration, Corrosion, & Structural Failure

There are roughly 26 million manholes in the United States, all constructed in thousands of different combinations of sizes, shapes and
materials. Despite their differences, many of these manholes have one thing in common. They are plagued with deterioration and corrosion
caused by hydrogen sulfide or H2S.

Although these harsh environments are common in wastewater systems, they can begin to deteriorate the structure and cause inflow
and infiltration issues. This became a major problem for cash-strapped municipalities that didn’t have the budget for expensive manhole
replacements. Fortunately, advancements in polyurea technology introduced the more affordable option of manhole rehabilitation.

These powerful before-and-after photos show the final stage of real projects:

Advanced Rehabilitation Technology (ART) helps municipalities, engineers, and contractors restore and protect manholes with proven rehabilitation solutions designed for long-term performance, not temporary fixes.

From active leaks to severe corrosion, our team evaluates real-world conditions and installs manhole linings that extend asset life, reduce I&I, and improve system reliability. We also utilize state-of-the-art CCTV inspection technology to identify and resolve minor issues before they turn into costly, time-consuming problems.

A Service-First Approach To Manhole Rehabilitation

What sets ART apart isn’t just the materials; it’s the people behind the work. Our trained field crews and certified applicators understand the challenges of working in live systems, confined spaces, and unpredictable field conditions. Every project is executed with a focus on safety, consistency, and long-term performance. Whether you’re planning a system-wide I&I reduction program or addressing isolated manhole failures, our team provides the expertise and support needed to move projects forward with confidence.

ART Helps Municipalities Take A Proactive Approach To I&I Reduction By:

Extending

the lifespan of existing infrastructure

By addressing I&I at the manhole level, systems become more efficient, more predictable, and more cost-effective to operate.

The ART Difference:
Experienced Crews.
Proven Results.

At ART, rehabilitation is more than applying a lining. It’s a process built around evaluation, preparation, and precision rehabilitation. Every project is tailored to the structure, environment, and severity of deterioration, ensuring the right solution is applied the first time.

Inflow and infiltration (I&I) is one of the leading drivers of increased treatment costs and system overload. Left unaddressed, it can strain capacity, increase energy usage, and lead to regulatory challenges.

Our Team Is:

Extend Asset Life Without Full Replacement

Full replacement isn’t always practical or necessary. ART’s rehabilitation services provide a cost-effective alternative that restores structural integrity and protects against future deterioration.
