Manhole Rehabilitation

Structural repair, corrosion protection, and infiltration control without full replacement

Manhole rehabilitation restores deteriorating manholes by addressing structural damage, corrosion, and groundwater infiltration without the need for full replacement. At Civil Solutions, we use proven rehabilitation methods to extend the service life of existing manholes, reduce inflow and infiltration, and protect underground infrastructure with minimal surface disruption.

Why Manhole Rehabilitation Matters

Manholes are exposed to constant stress from traffic loads, groundwater, corrosive sewer gases, and aging materials. Over time, these conditions lead to cracking, corrosion, infiltration, and structural weakening. When deterioration is left unaddressed, failing manholes can contribute to inflow and infiltration, higher treatment costs, and safety risks throughout the collection system.
Manhole rehabilitation addresses these issues by restoring structural integrity, sealing active leaks, and protecting concrete surfaces from further deterioration. A properly rehabilitated manhole extends the life of existing infrastructure and helps avoid the cost and disruption of full replacement.

Common Manhole Problems We Address

Before

Cracked or Deteriorated Concrete

Surface spalling, cracking, and material loss that weaken structural integrity over time.

Before

Active Infiltration and Leaks

Groundwater entering through joints, cracks, or pipe penetrations.

Before

Corrosion from Sewer Gases

Concrete deterioration caused by hydrogen sulfide and other corrosive environments.

Before

Failing Joints and Chimneys

Leak paths at seams, frames, and grade rings that allow water intrusion.

Before

Structural Weakness in Aging Manholes

Loss of load-bearing capacity due to long-term wear and environmental exposure.

Our Manhole Rehabilitation Approach

Our manhole rehabilitation process focuses on resurfacing deteriorated manholes to restore structural integrity, address corrosion, and stop infiltration. Each step is performed with long-term performance in mind.

Inspection and Evaluation

Each manhole is evaluated to identify structural damage, infiltration points, and corrosion. This assessment allows us to determine the most effective rehabilitation method based on condition, environment, and service requirements.

Surface Preparation

Deteriorated material is removed, and surfaces are cleaned to ensure proper bonding. Proper preparation is critical to the long-term performance of any rehabilitation system.

Manhole Resurfacing

A structural resurfacing system is applied to rebuild deteriorated surfaces, restore structural integrity, and protect against future corrosion. The resurfacing process creates a uniform, durable lining designed to extend the service life of the existing manhole.

Sealing and Final Protection

Pipe penetrations, joints, and chimneys are sealed to eliminate active leaks and prevent future infiltration. The completed resurfacing system provides a continuous, protective barrier throughout the structure.

Rehabilitation Classes and Their Applications

Class A Rehabilitation Materials

Class A methods offer comprehensive solutions, preventing I&I and reconstructing manholes to withstand heavy loads. These solutions encompass prefabricated inserts, steel-reinforced concrete, fiber-reinforced polymers, and specialized cement products.

Class B Rehabilitation Materials

Class B methods offer semi-structural solutions to improve the residual strength of manholes, such as spray-applied polymeric linings, cured-in-place manhole liners, and cementitious linings capable of withstanding hydrostatic pressure.

Class C Rehabilitation Materials

Class C methods focus on providing non-structural protection against corrosion and addressing minor leaks. These methods include thin-applied polymeric and cementitious linings, rubber joint seals, and inflow dishes for the top parts of manholes.

Tailored Solutions for Every Need

We assess the condition of each manhole and determine rehabilitation objectives to suggest the most efficient materials and methods, ensuring both cost-effectiveness and long-term performance.
