Excavation in La Petite-Nation, with our own excavator

At Wilfrid David, plumbing and excavation are handled by the same team: the crew that digs the trench also lays the pipe in it, which makes the work simpler to coordinate.

The short answer

Wilfrid David, in Chénéville, does excavation all over La Petite-Nation with its own excavator: trenches for water and sewer lines, foundations, septic fields, grading and demolition. We also install the plumbing that goes into the excavation. Call 819-428-3161.

What we dig

We dig trenches to bring water from the well to the house or sewage from the house to the tank, foundations for a new home, a garage or an addition, and leaching fields when a septic system needs building or replacing. We also excavate around foundations to redo a French drain.

We also do grading, so the yard slopes water away from the house, and demolition. Photos of past projects are available in our work.

One contractor for excavation and plumbing

When excavation and plumbing are handled by two different companies, the work has to be coordinated between them, and a trench that is too shallow or in the wrong place can delay the job.

We do both. The excavator operator knows exactly what will be installed in the trench. We dig, lay the line, make the connections and backfill. This makes coordination simpler and reduces the risk of errors.

Water lines installed below the frost line

In this region, a water line that is not buried deep enough is likely to freeze. How deep to go depends on the soil, how much snow sits on it in winter, and whether vehicles drive over it. We factor that in when we dig, and where we can't get deep enough, we protect the line some other way. If your line already freezes every winter, see our thawing and heat cable page.

Before excavation begins

Wires and pipes may be buried in unexpected places. Before digging, you can request a free locate from Info-Excavation, as the Régie du bâtiment du Québec recommends. For a foundation, a septic field or a demolition, your municipality may also require a permit, so check with them.

To discuss a project, describe it through the contact page or call Monday to Friday, 8 a.m. to 5 p.m., and Saturday, 9 a.m. to 1 p.m. For a broken line flooding the yard, see our 24/7 emergency page.

Common questions

Your questions, answered

Does Wilfrid David have its own excavator?

Yes. Wilfrid David, in Chénéville, owns its excavator and does the digging itself. The same company digs and does the plumbing, which keeps water line, sewer line and septic jobs simple.

Do I need buried lines located before digging?

Yes, it's strongly recommended. In Quebec, locate requests are free through Info-Excavation, and the Régie du bâtiment du Québec encourages making one before excavation work. It tells you what underground networks run under your property.

How deep should a water line be buried?

Deep enough to be below the frost line, which varies with soil, snow cover and vehicle traffic. There's no single number that fits every lot. Wilfrid David takes it into account when digging, and protects the line another way where it can't go deep enough.

Do I need a permit to dig a foundation or put in a septic field?

In Quebec, a septic field needs a municipal permit under regulation Q-2, r. 22. For a foundation or a demolition, your municipality may require a permit as well. Check with yours before you start.

Do you do demolition?

Yes, demolition is part of the excavation work Wilfrid David does out of Chénéville. Describe the project to us at 819-428-3161 so we can assess what is feasible.
