We are proud to be the Calgary’s Sewer Camera Inspection Experts. At Certa Property Inspections, we strive to be the leaders in the industry and are accredited through the PACP certification program and have since performed hundreds of sewer camera inspections. We strongly encourage our clients perform sewer camera inspections prior to the purchase of any structure to check for defects in the waste line. Root blockages, grease blockages, line fractures and collapses are regular sightings that we find during sewer line inspections. We feel that it is best to know what the status of the sanitary line before you end up with a dirty situation!
Typical sewer line material composition:
Pre 1960s: No corrode aka orangeburg, this material is simply paper and tar that is highly prone to collapse and ovality (deformation) with an expected lifespan of 50 years.
1960-1980: Ventrified clay tile pipe, this material was typically installed in short sections ranging between 2-4 feet and is highly prone to root intrusion and can succumb to fractures.
Post 1980: PVC-35 is the common sanitary material that is installed in residential homes in Alberta. While this material is a much better product, the common issues found with this material are deformities caused by poor backfilling practices when the line was installed. Hard clay and large stones that are not screened out of the backfill can cause deformations in the pipe which reduce the strength and integrity of the material.
