Manhole Restoration with SewperCoat®

Manhole Restoration with SewperCoat®: A Long-Term Solution for Aging Infrastructure

Aging sewer infrastructure is a growing challenge for municipalities, commercial facilities, and industrial sites. One of the most vulnerable components of any wastewater system is the manhole. Constant exposure to hydrogen sulfide (H₂S), moisture, and corrosive environments can lead to severe structural deterioration if not addressed on time.

At DRC Construction, we provide professional manhole inspection, cleaning, and rehabilitation services, including advanced restoration systems like SewperCoat®, designed to extend the life of underground infrastructure.

Common Problems in Deteriorated Manholes

Over time, manholes may experience:

• Concrete corrosion caused by H₂S gas

• Cracks, spalling, and exposed aggregate

• Infiltration and inflow (I&I)

• Structural weakness that compromises system safety

• Increased maintenance and emergency repair costs

Without proper rehabilitation, these issues can escalate into system failures, environmental hazards, and costly replacements.

What Is SewperCoat® Manhole Restoration?

SewperCoat® is a high-performance, spray-applied epoxy coating system specifically engineered for wastewater structures. Once applied, it creates a monolithic, corrosion-resistant barrier that protects manholes from further chemical and biological attack.

This system is ideal for restoring deteriorated manholes while avoiding the disruption and expense of full replacement.

Key Benefits of SewperCoat®

• Exceptional corrosion resistance against H₂S and aggressive sewer gases

• Structural enhancement when applied at appropriate thickness

• Fast application and curing, minimizing downtime

• Seamless, joint-free lining that prevents infiltration

• Long service life, reducing long-term maintenance costs

These advantages make SewperCoat® a reliable solution for both preventive maintenance and active rehabilitation projects.

Applications

SewperCoat® is suitable for:

• Sanitary sewer manholes

• Stormwater manholes

• Lift stations and wet wells

• Precast and cast-in-place concrete structures

It can be applied to a wide range of diameters and configurations, making it a versatile option for municipal and commercial systems.

Our Rehabilitation Process at DRC Construction

Every manhole restoration project begins with a detailed approach:

1. CCTV Inspection to assess structural condition

2. Thorough cleaning to remove debris, grease, and corrosion

3. Surface preparation to ensure optimal coating adhesion

4. Professional SewperCoat® application by trained technicians

5. Final inspection to verify quality and performance

This process ensures long-lasting results and compliance with industry standards.

Why Choose Manhole Rehabilitation Over Replacement?

Rehabilitation offers significant advantages over full replacement:

• Lower overall project costs

• Reduced excavation and surface disruption

• Shorter project timelines

• Extended service life of existing infrastructure

For many systems, rehabilitation is the most efficient and cost-effective solution.
