About Dimartech
Engineering-led since 2000.
Since 2000, Dimartech has done one thing properly in Montréal: engineer custom process equipment before building it. Owners, EPC contractors and equipment manufacturers across Canada and the United States bring us the equipment that can’t be late or wrong.

Our shop
We build what we engineer.
Design and fabrication happen under one roof in Pointe-aux-Trembles, with a partner network for NDE, heat treatment, machining and coatings.
Our promise
Four commitments on every project.
We review before we build
A licensed engineer checks your design, code and materials before fabrication starts.
We tell you early
If something in the drawing will cause a problem, you hear it from us before it costs you.
We document everything
Calculations, material certificates, NDE and hydro-test records, ready for your Authorized Inspector.
We protect your date
We plan around your schedule, and engineer alternatives when materials threaten it.
How a project works
Every project follows the same six steps.
We describe each step in plain language, so procurement, engineering and project management all know what comes next.
01 RFQ
Drawings, spec or problem
02 Engineering review
Design, code, materials, schedule
03 Firm bid or ROM
Clear scope and price for stakeholders
04 Calculations to your inspector
Accepted by your Authorized Inspector
05 Fabrication & NDE
RT · UT · PT · PMI · hydro
06 Delivery & start-up
