Quand devrait-on prévoir la construction d’un mur de soutènement?

Dès que vous faites face à un dénivelé important qui menace la stabilité de votre terrain. Un mur de soutènement en pente permet de prévenir les affaissements qui pourraient fragiliser vos fondations ou vos aménagements paysagers, de stopper l’érosion et de maximiser la surface utilisable de votre terrain.

Quel est le meilleur choix: un mur de soutènement en bloc de béton ou en pierre?

Le choix dépend de la nature du sol et du look recherché. Un mur de soutènement en bloc de béton offre une grande précision, idéale pour les zones restreintes ou les designs modernes. À l’inverse, un mur de pierre naturelle ou un mur de soutènement en roche est souvent privilégié pour les grands terrains des Laurentides, car il est plus flexible face aux mouvements du sol.

Pourquoi mon ancien mur a-t-il commencé à pencher?

Dans la plupart des cas, l’eau est responsable, pas le matériau. Sans un drainage adéquat, la pression hydrostatique et le gel poussent contre la structure. Lors de l’excavation d’un mur de soutènement, nous intégrons systématiquement une zone de drainage pour évacuer l’humidité. C’est ce qui différencie un mur qui dure 5 ans d’un autre qui perdure plus longtemps.

Pouvez-vous construire un mur de soutènement près de fondations existantes?

Oui. C’est un défi fréquent en zone résidentielle et une préoccupation pour les autoconstructeurs et les entrepreneurs généraux. Grâce à notre parc d’excavatrices de différentes tailles, nous pouvons construire un mur de soutènement à quelques pieds d’une fondation existante, sans exercer de pression sur vos structures actuelles.

Quel est le prix d'un mur de soutènement au Québec?

Le prix d’un mur de soutènement varie selon sa hauteur, sa longueur et le type de matériau. L’accessibilité du site pour les machines a également un impact sur les frais. Pour obtenir un budget réaliste et éviter les surprises, nous recommandons toujours une visite de chantier. Cela nous permet d’évaluer la nature du sol et de vous proposer la solution la plus durable pour votre investissement.

Retaining
wall

The topography of the Laurentians and Lanaudière is magnificent, but often poses construction challenges. Whether it's to extend a parking lot, create a tiered terrace or stabilize an embankment, we build solid retaining walls that defy time and freeze-thaw cycles.

Our construction services retaining wall

Before excavating, we take the time to analyze the site as a whole: soil bearing capacity, lateral thrusts and environmental constraints. We master the best excavation techniques, geotechnical stability and drainage management for an intelligently integrated retaining wall that doesn't move.

Thanks to an in-depth reading of the terrain, we determine the optimum approach for each residential or commercial project. With nearly 50 years of expertise and a fleet of modern machinery, our team of 140 employees knows how to avoid subsidence, cracks and deformation.

Transparency

Each quotation is based on a precise calculation of backfill volumes, stone quantities and compaction times. You'll receive a clear, detailed estimate with no unpleasant surprises.

Coordination

We plan our excavation work according to the stages that follow: formwork, landscaping, asphalting. This avoids last-minute adjustments, rework and friction between trades.

Sustainability

From drainage management to geotextile selection, every stone, riprap or concrete block retaining wall is built to the highest standards. The result: a stable, safe site that protects your investment for decades to come.

We're digging into
your questions

When should a retaining wall be built?

As soon as you're faced with a steep slope that threatens the stability of your land. A sloping retaining wall prevents subsidence that could weaken your foundations or landscaping, stops erosion and maximizes the usable surface area of your land.

Which is better: a concrete block or stone retaining wall?

The choice depends on the nature of the soil and the desired look. A concrete block retaining wall offers great precision, ideal for restricted areas or modern designs. Conversely, a natural stone or rock retaining wall is often preferred for large Laurentian lots, as it is more flexible in the face of ground movement.

Why did my old wall start to lean?

In most cases, the water is responsible, not the material. Without proper drainage, hydrostatic pressure and frost push against the structure. When we excavate a retaining wall, we systematically incorporate a drainage zone to evacuate moisture. This is the difference between a wall that lasts 5 years and one that lasts longer.

Can you build a retaining wall near an existing foundation?

Yes, it's a common challenge in residential areas and a concern for self-builders and general contractors. Thanks to our fleet of excavators of various sizes, we can build a retaining wall within a few feet of an existing foundation, without putting pressure on your existing structures.

How much does a retaining wall cost in Quebec?

The price of a retaining wall varies according to its height, length and type of material. The accessibility of the site for machinery also has an impact on costs. To obtain a realistic budget and avoid surprises, we always recommend a site visit. This enables us to assess the nature of the soil and propose the most sustainable solution for your investment.
