Main Lateral CCTV Inspection & Depth Sonding
High-resolution optical investigation through residential and commercial sewer laterals. Utilizing 512Hz transmitting sondes to pinpoint lateral depth and underground location.
Required before high-torque cutting to identify shifted clay joints, shear fractures, or thin-walled Orangeburg pipe.
- Slow draining fixtures throughout the entire main level or basement.
- Basement floor drain bubbling or gurgling violently during washing machine drain cycles.
- Recurring annual springtime sewer backups tied to seasonal ground frost shifts.
- Approximate year of structure construction (determines vitrified clay vs. PVC vs. cast iron).
- Physical accessibility to basement mainline cleanout valve (stack location clearance).
- Recent landscaping, tree plantings, or heavy driveway construction on front easement.
We clear and document lateral lines up to the private property boundary line. Structural collapses inside municipal mains are packaged into an immediate digital inspection brief for City of Winnipeg Water & Waste (311).
