Add-on laser measurement for CCTV pipe inspections

Laser profiling is a valuable add-on to CCTV pipeline inspections when more detail is needed about a pipe’s shape, ovality and internal profile. While standard CCTV footage provides a clear visual record of the pipe condition, laser profiling adds measurable information that can help identify deformation, deflection and changes in pipe geometry.

At HD Inspections, laser profiling can be used alongside CCTV inspections for sewer and stormwater pipelines, particularly where ovality, pipe integrity or installation quality needs to be assessed.


What Is Laser Profiling?

Laser profiling uses a laser ring or laser measurement system mounted with the CCTV inspection camera to project a visible profile onto the inside wall of the pipe.

As the camera travels through the pipeline, the laser allows the internal shape of the pipe to be reviewed and measured. This is especially useful for identifying whether a pipe has remained round or has become deformed, flattened or out of tolerance.

Laser profiling is commonly used on:

  • Flexible pipes

  • Plastic and polypropylene pipelines

  • Newly installed sewer and stormwater assets

  • Subdivision handover inspections

  • Off-maintenance inspections

  • Pipelines where deformation is suspected

  • Assets requiring additional quality assurance

Why Check Pipe Ovality?

Pipe ovality refers to how much a pipe has moved away from its original round shape. In flexible pipes, some deflection may occur after installation, but excessive ovality can indicate problems with installation, bedding, compaction, ground movement or loading.

Checking ovality can help identify issues such as:

  • Pipe deformation

  • Flattening or deflection

  • Installation-related stress

  • Ground movement impacts

  • Poor bedding or compaction support

  • Potential structural concerns

  • Sections requiring further investigation

For civil contractors, developers and asset owners, laser profiling provides an additional level of evidence beyond standard CCTV footage.

Laser Profiling as a CCTV Inspection Add-On

Laser profiling is not always required for every pipeline inspection, but it can be highly useful when a project specification calls for ovality checks or when the pipe material and site conditions make deformation a concern.

It is commonly added to CCTV inspections for:

  • New asset handover

  • Off-maintenance submissions

  • Council or authority requirements

  • Quality assurance inspections

  • Defect investigations

  • Flexible pipe assessment

  • Post-construction condition checks

By combining CCTV footage with laser profiling, clients receive both a visual inspection record and measurable information about the pipe’s internal shape.

Benefits of Laser Profiling

Laser profiling can assist with:

  • Confirming pipe ovality and deflection

  • Identifying deformation not easily visible on standard CCTV

  • Supporting council and asset owner handover requirements

  • Providing additional evidence for construction quality assurance

  • Helping determine whether further investigation or rectification is required

  • Improving the value of CCTV inspection data

This makes it a practical add-on for projects where pipe integrity and installation quality need to be clearly documented.

Laser Profiling for Sewer and Stormwater Pipelines

HD Inspections can provide laser profiling alongside CCTV inspections for suitable sewer and stormwater pipelines across Queensland and Northern NSW.

This service is particularly useful for civil contractors, councils, developers, engineers and asset owners who need more than video footage alone to assess pipe condition, ovality or structural performance.
