Denis Drolet started Préven-Tech in 1989 in Jonquière with a vibration analyser and a simple idea: Quebec's industry deserves independent people who work for the owner, not the contractor. Thirty-five years later, it's still a family business. Six services, same values.
Every service we offer today started because a client asked, "Can you do this too?" That's how it was built, one need at a time.
Denis Drolet launches Préven-Tech in Jonquière. One man, one vibration analyser, and the Saguenay smelters as his first clients. The company logo still nods to those roots.
Clients start asking: "Since you're already in our equipment, can you manage the technical records too?" That's where structured preventive maintenance takes shape.
Big expansion projects arrive in the aluminum sector. Clients want someone independent to watch the sites and manage the projects. Préven-Tech is neither an engineer nor a contractor, and that's precisely its edge.
The crisis hits. Plants are cutting everywhere. Préven-Tech trains a team in inventory and procurement, because when money's tight, that's where every dollar counts the most.
Six services, same independence. Rio Tinto Alcan, ArcelorMittal, Niobec, Resolute and other names that speak for themselves. And still a family business from the Saguenay.
Three things our clients tell us regularly. "You're the only ones who truly work for us." "Your people are genuine professionals." "We know you'll tell us the truth." That's not accidental. It's been built that way from the start.
We can't bid on the projects we manage. It's structural: we're neither engineers nor contractors. So when we evaluate a supplier or challenge an invoice, it's only in your interest. Zero conflict.
The people who work for us aren't numbers. We send them into heavy plants, onto complex job sites: the trust has to be there. We take care of our people because they're the ones taking care of your facilities.
You call, we're there. One-off or recurring
We sit down, look at the situation, and recommend
Our people at your site, full-time. Your team, our expertise
One engineer shared across 2-3 plants. The expertise without the full cost
They trust us
We send people into smelters, mines, heavy construction sites. Zero accident isn't a slogan on a wall. It's the only acceptable target when it's your people in there. From the first day of the mandate to the last.
« HSE starts before we set foot on site. It ends when the last one of our people has walked out through the gate. »
We get a lot of requests. To be fair to everyone, we've set seven clear criteria. If your project checks those boxes, let's talk.
Does it relate to engineering, technical fields, the industrial community? We sponsor what we know.
Post-secondary education, homelessness, community food programs: the causes we prioritize.
Show us how your project makes room for everyone. Not just in theory.
We'll be honest: we'd like it to reflect a bit on us too. Local visibility, regional reach.
We'd rather get involved for the long haul than sign a cheque once and move on.
Send us a clear plan: what it is, what it costs, who it reaches. The form is below.
Give us lead time. A request that lands the day before the event is hard to take seriously.
Take 10 minutes to fill out the form. Tell us what your project is, what it needs, and why it matters.
Fill out the formSince 1989. Denis Drolet started it in Jonquière with vibration analysis. The '90s brought equipment records management. The 2000s brought project management and site monitoring. After the 2008 crisis, inventory and procurement joined the offering. Today it's six services, each one added because a client asked for it.
Because we're structurally unable to bid on what we manage. Not engineers, not contractors, not suppliers. That wipes out all conflicts of interest in one shot. When we tell a supplier their price is too high, we've got nothing to lose.
Rio Tinto Alcan, ArcelorMittal, Niobec, Resolute, General Cable, Port Saguenay, the CIUSSS, Fibrek, BlackRock and Elkem, to name a few. Aluminum, mining, forestry, port operations, healthcare. Pretty much everything industrial in the Saguenay, the North Shore and beyond.
Through the official form. We look at seven things: mission alignment, social impact, diversity, visibility, long-term partnership potential, and whether the plan holds up (budget, timeline, measurable impact). Send it in advance, not the day before.
