Know What Lies Below the Lid
A manhole sits at the surface, but the structure beneath it tells the real story of a collection system’s condition. Corrosion, infiltration, failed joints, separated connections, and structural deterioration often spread out of sight until a problem forces the issue.
LSEC provides documented manhole inspections that put trained eyes on every structure, giving operators, engineers, municipalities, and utility districts a clearer picture of what their system looks like beneath every lid.
A Closer Look at Every Structure
A manhole inspection is not a quick glance through an open lid. It is a structural evaluation that documents visible conditions from the frame and cover down to the pipe connections at the base.
Frame & Cover
Identify poor seals, surface water entry points, loose covers, and visible signs of stress at the access point.
Chimney & Corbel
Document corrosion, cracking, spalling, and deterioration that often go unnoticed from street level.
Walls & Bench
Evaluate structural condition, material loss, joint issues, and damage that may require repair or rehabilitation.
Pipe Connections
Inspect the base of the structure where separation, infiltration, blockage, and serious failures often begin.
The LSEC Standard
LSEC brings the same level of rigor to every structure regardless of size, age, or condition. Every visible defect is documented with its description, location, and supporting photos, creating a record engineers and operators can use immediately.
- Frame & cover condition
- Chimney and corbel inspection
- Wall deterioration documentation
- Bench and channel review
- Pipe connection inspection
- Infiltration point identification
- Photographic documentation
- Repair priority reporting
Reading the Warning Signs Below
A manhole rarely fails on its own. Corrosion at the chimney or frame can point to hydrogen sulfide gas exposure. Cracking or spalling in the walls can signal structural stress. Infiltration through a failed joint adds unnecessary volume to the collection system. Left unaddressed, these issues can turn straightforward repairs into full replacement projects.
Corrosion
Possible gas exposure and long-term material loss.
Cracking
Structural stress that can worsen over time.
Infiltration
Unwanted flow entering through joints or defects.
Separation
Connection failures that can drive downstream problems.

Frequently Asked Questions
What does a manhole inspection include?
A manhole inspection typically includes review of the frame, cover, chimney, corbel, walls, bench, channel, pipe connections, joints, visible defects, infiltration points, and structural condition.
Why are manhole inspections important?
Inspections help identify corrosion, infiltration, cracking, spalling, separated connections, and other issues before they lead to collapse, emergency repair, or costly rehabilitation.
Can inspections help with capital planning?
Yes. Documented inspection reports give utilities and engineers a clearer basis for prioritizing repairs, budgeting rehabilitation work, and building long-term asset management plans.
Do you inspect both brick and concrete manholes?
Yes. Brick and precast concrete structures age differently, and LSEC evaluates each structure based on its material, age, condition, and service environment.
Can LSEC inspect one structure or an entire system?
Yes. LSEC can inspect a single structure flagged by a complaint or support larger inspection programs across municipal, utility district, industrial, or commercial systems.

Spot Failure Before It Costs You. Inspect Before It Fails.
A manhole that has never been inspected carries a condition no one can verify. LSEC gives you the documentation needed to understand, prioritize, and protect the structures below the lid.
