Manhole Inspections

Semtex Trenchless Solutions provides conventional and high-resolution digital inspections of wastewater, stormwater and industrial manholes, chambers and access structures.

Our specialist 360-degree manhole inspection system records the complete internal surface of the structure in high-resolution 8K imagery. This creates a detailed digital record that can be reviewed, measured and assessed after the field inspection has been completed.

Our capabilities include:

• High-resolution 360-degree manhole scanning

• 8K internal imagery

• Inspection of walls, covers, channels and benches

• Pipe connection and junction inspection

• Identification of cracking, corrosion and material loss

• Groundwater infiltration assessment

• Dimensional referencing and measurement support

• Digital asset records and condition monitoring

• WinCan reporting and cloud-based review

• Integration with associated pipeline CCTV records

Defects and conditions identified

Inspections can identify cracking, displaced joints, corrosion, missing mortar, exposed aggregate or reinforcement, infiltration, defective pipe connections, damaged channels and benches, root intrusion, surface erosion and evidence of structural movement.

Digital inspection benefits

The complete visual record can be reviewed by asset owners, engineers and contractors without returning to site. It also supports consistent defect assessment, repair planning and comparison of the same asset over time.

Using a remote inspection system can reduce the need for confined-space entry during routine assessment. Where physical entry is required, appropriate confined-space controls, gas monitoring, rescue planning and permits are used.

Typical applications:

• Council wastewater and stormwater networks

• Pre-rehabilitation condition assessment

• Construction and handover inspections

• Investigation of infiltration or corrosion

• Asset inventory and baseline surveys

• Planned maintenance and renewal programmes

• Post-rehabilitation verification
