Founded in 1975 by Ernest Alexander, Visu-Sewer was started with a core group of employees dedicated to providing the highest quality sewer inspection and maintenance services in the industry. During the first few years, the company focused primarily on sewer cleaning and inspection work. During these formative years techniques such as hydro-jet flushing and CCTV Inspection were developed. Visu-Sewer was instrumental in the refinement of these techniques which have been adopted by many others within the trenchless industry. In the 1980?s, Visu-Sewer?s scope of work spread to rehabilitation services such as Chemical Grouting, Sliplining, Manhole Lining and Fold and Formed Lining. Inspect. Maintain. Rehabilitate. Relax.
