Pipeline Welding
We specialize in precision pipeline welding for water transmission systems, adhering to AWS and ASME standards. Our team handles diameters from 6 to 98 inches, using advanced techniques for butt welds and backing bars. Clients rely on our 40+ years of expertise for leak-proof, durable solutions in challenging environments.
Tunnel Welding
Our tunnel welding services address complex projects like the 800-foot-deep Roundout Tunnel bypass. We install steel linings in diameters up to 16 inches, ensuring structural integrity in high-pressure environments. Safety and precision are prioritized, with teams operating in compliance with CSA standards.
Shaft Welding
We execute shaft welding for hydroelectric and municipal projects, including 240-foot vertical installations. Our process involves multi-layer welds for 5/8-3/4 inch steel, ensuring stability in seismic zones. This expertise was critical for the Kemano Backup Tunnel's 132-inch diameter shafts.
Penstock Installation
We install penstocks for hydroelectric facilities, such as the 144-inch pipe in British Columbia's Upper Lillooet project. Our work accommodates steep gradients and variable thicknesses, ensuring efficient water flow for power generation under extreme conditions.
Pipeline Relining
Our relining services extend pipeline lifespans without full replacement, as seen in the $1M Bernasconi Re-Liner project. We apply 5/8-3/4 inch steel overlays in active water systems, minimizing downtime while maintaining structural integrity for municipal clients.

Report
My husband just went to Dean's Welding today. We had one very small part that needed welded to another. Dean did it quickly and it came out great and because it was so small of a job he didn't charge us. I feel bad about that because he really could have, we were just so happy to get it done. I know it didn't take him very long but it was still a very generous thing to do and we will certainly recommend him to anyone that needs welding done. I will pay this forward by doing something similar for someone when I have the opportunity.
