Before we pour

The best place to save money is the plan.

Four steps

1 / 4

You send your plans

Without plans, no one can give you a firm price.

2 / 4

We review the plans and quote

Pierre has quoted formwork for 40 years. He sees what won't work on the jobsite.

3 / 4

A problem with the plan? We call the engineer or architect

Whatever is off gets fixed before the pour, not after.

4 / 4

You receive a quote with a price

And often savings: on a project, that can add up to tens of thousands of dollars.

“At the end of the day, you can save tens of thousands just with his experience.”

Why clients choose us

The ones who don't choose us already have their formwork crew in mind. The clients who go with us, it's because of the contact we have with them. Reassuring clients, above all: explaining what foundations are, how it's done, the steps from A to Z. Clients like knowing that, and they like that we follow up all the time. Doing the quote, sending it, calling them, walking the lot with them, talking to the excavation guys. That makes all the difference. Even if we're sometimes a bit more expensive, it often comes down to the approach we have with the client.

40 years of quoting experience

At Coffrage XP, having an experienced team matters. Pierre, at the office — the estimator — has been doing quotes for 40 years. He knows every little flaw in formwork: when you hand him a plan, he sees every detail that won't work. He calls, he talks to the technologist, he talks to the engineer. A lot of things get put in a plan for nothing, and that creates costs we're able to reduce. The difference of having a guy like Pierre on quotes is that at the end of the day, you can save tens of thousands just with his experience.

Why the foundation decides everything

A foundation done wrong from the start, you'll pay for it for the life of the house. When someone builds a house, the foundation is the base of everything: it's what ensures long-term solidity. Clients often think it's not that important because once it's poured, you don't see it anymore. But if the formwork is done wrong from the start, the problems show up later: cracks, settling, alignment problems, water infiltration. In the end, doing things right at the start costs less than redoing everything after. That's why at Coffrage XP, we take that step seriously.

We're not for every project

Coffrage XP isn't for every construction project. We work for clients who are looking for quality and reliability. If you're after the lowest price, that's not where our services bring the most value. We're looking for long-term relationships. The clients I have right now are all clients we've been working with for a long time. We've built a relationship with them. We mostly work with contractors and clients who understand the quality of formwork.

A day on our jobsites

The days start at 5 a.m., and what time they end, you never know. You get up in the morning, grab a coffee, head out, go see the guys on the jobsite, get them started. After that, I go by my priorities: I've got a big job in Laval, a job in Mirabel. Depending on the day's priority, on who's in a rush and who needs me there, that's the jobsite I head to. It's a lot of planning: project schedules, drawings, and materials. I make sure the guys never run out of stock.

Structural slabs

Doing structural slabs has always been a challenge, and it's always been a dream. We wanted to get there. By working hard, with the right people and the right crews, we made it. Before, we weren't able to do them. Now we just keep growing and keep getting better, day after day. That's what experience is: when you know where you're going and you do what you have to do, things go well.

How soon can you do my formwork?

For a house, plan on about a month between your call and the end of the job. When the calendar allows it, it can be done in two or three weeks. It's the question we get asked the most, and it's also what sets Coffrage XP apart: when a date is given, the crew is there, and the job gets done completely.

How much does foundation formwork cost?

Coffrage XP doesn't post a price per square foot: every project is quoted from your plans. The type of project, site access, and the schedule all move the number. Send your plans and you'll get a firm price.

Do I need plans before contacting you?

No. Without plans, Coffrage XP can't produce a priced quote, but we can call you, walk you through the steps, and guide you along. Just tell us where you're at in the form.

What types of formwork do you do?

Three techniques: Duraform, a patented forming system, for every sector; structural slabs, including floor by floor; and prefabricated PERI walls. Coffrage XP covers residential, heavy residential, commercial, and industrial.

What's the difference between a structural slab and a slab on grade?

A slab on grade sits directly on the ground. A structural slab spans open space: it makes room for a basement, an underground parking level, or a floor above. It's the one you need as soon as there's open space underneath.

Is it better to pour a wall on site or use a prefabricated wall?

A wall poured on site adapts to any shape. A prefabricated PERI wall arrives already built and comes off the jobsite's critical path, which saves days when the schedule is tight. Coffrage XP does both and will tell you which one fits your project.

Why does the quality of a foundation matter so much?

Because a poorly built foundation gets paid for over the entire life of the building. Once the concrete is poured, you can't see it anymore, but the problems show up later: cracks, settling, poor alignment, water infiltration. Doing it right the first time costs less than doing it over.

Which cities do you work in?

Coffrage XP serves the greater Montreal area: Lachute, Laval, Joliette, Rawdon, Saint-Jérôme, Terrebonne and Sainte-Adèle. For a project further out, we travel if the scope justifies it.

Do you work through the winter?

Yes. Coffrage XP crews form year-round, with the protections and methods suited to cold-weather work.
