Afonso Group has been providing cleaning and inspection services for more than 20 years. We are one of the largest pipe cleaning and inspection services in Newfoundland and Labrador, with a crew of experienced, trained people and the latest equipment and technology.

We have performed work for all the major plumbing contractors and property management firms in the province, as well as breweries and the food industry, and numerous municipalities including the City of St. John's. Our client list includes the Terra Nova offshore energy project, Hibernia, North Atlantic Petroleum, St. John's Health Care Corporation, Newfoundland and Labrador Housing Corporation, as well as the provincial and federal governments.

Afonso Group specializes in the cleaning and inspection off all types of pipe, for a wide range of clients, from municipal customers to the offshore oil and gas industry. We are the first independent contractor in Newfoundland and Labrador to introduce closed-circuit TV inspection, polly pig water main cleaning and Sewerjet sewer cleaning. We deploy a diverse range of skills and equipment to ensure the job gets done right, each and every time. Our service offerings include the following technologies and capabilities:
  • Video Inspection
  • High Pressure Cleaning
  • Pipe Fusing
  • Pipe Tracking
  • Polly Pigging
  • Pipe Lining
  • Pipe Line Hot Taps

Using highly specialized, closed-circuit cameras, we can perform visual inspection of all pipe systems, from as small as 6 millimeters - or 1/4 inch - in diameter up to any size. Our closed-circuit cameras are the most reliable and effective way to detect leaks and inspect welds in pipeline systems. And we are experts at overcoming difficult challenges - if it can be done, Afonso Group can deliver. We have performed video inspections in sewer lines, household and commercial sewer cleanouts, hydro facilities, refineries and offshore installations.


We use high-pressure water jets to break the most stubborn blockages in sanitary and storm pipe systems. We have powerful accessories that are capable of cutting through root systems and most other forms of blockages.


We carry out pipe fusing operations for many clients, in which we utilize various techniques to seamlessly weld two pieces of high density polyethylene pipe into one.


Do you have a leak in a network of underground pipelines that you can't locate? We insert transmitters into the pipeline to locate the problem to within several feet, saving the contractor time and money. Tracking equipment is available for any size pipe.


Polly pigging utilizes bullet-shaped foam 'pigs' to clean restricted pipelines, including industrial, hydroelectric, petroleum and water distribution pipelines. The pigs are hydraulically or pneumatically propelled through the pipeline, usually starting with a smaller pig and moving to larger, more abrasive ones. This has proven to be the safest, fastest and most cost-effective way to clean pipelines.

We also offer pipe lining, pipe trenching/bursting and ground penetrating radar services.


Our offshore inventory includes a containerized confined space entry kit, including certified, explosion proof compressors that can supply air for up to four persons on a continuous, 24 hour basis. The container is pre-packed for immediate, incident-free transportation offshore. It includes umbilicals, air panels, low pressure and high pressure back up systems, certified breathing masks, and all necessary peripherals. The kit is staffed by a minimum of two technicians, who have comprehensive Confined Space Entry training.


Using closed circuit video cameras, we perform corrosion monitoring and weld integrity inspection on process pipe systems. Perhaps our most challenging assignment to date has been the inspection of pipeline systems on the Terra Nova FPSO, the ground-breaking Floating Production Storage and Offloading vessel for the Terra Nova oil field, offshore Newfoundland. This project involved the complete and thorough inspection of every pipe on the FPSO, including hydrocarbon, firewater, potable water and all other pipe systems, to ensure that all joints were sound and technical specifications were met. We have also performed pipe cleaning and inspection service for the North Atlantic Petroleum refinery in Come by Chance.
