Experts in Geotechnical Engineering and Materials Inspection in Southwestern Ontario


CMT Engineering Inc. designs Class IV on-site sewage disposal systems for private residences, commercial buildings, industrial developments, or institutional developments. The subsurface investigation includes on-site supervision of test pit excavations, laboratory analysis for percolation time determination, detailed AutoCAD design drawings and a report. The report provides details, design and specifications for the proposed sewage system, for the client to obtain an installation permit as provided by Part 8 of the 2012 Ontario Building Code, as amended in 2019. Inspections and certification of the sewage disposal installation are carried out during construction. A final engineered-stamped report will be issued upon final completion. We also assess existing sewage disposal systems and provide recommendations for additions or renovations, and troubleshooting of existing sewage disposal systems.

CMT Engineering Inc. also performs laboratory analysis for percolation time assessment of individual sewage disposal systems, either sampled by us or by the client and delivered to our laboratory.
