Why Choose Carmine et Fils for Your Retaining Wall?

Retaining walls need to be built properly from the ground up. A wall that only looks good on the surface can shift, lean, crack or fail if the base, drainage and soil pressure are not handled correctly. In Montreal, retaining walls also need to deal with freeze-thaw cycles, spring melt, heavy rain and changing ground conditions.

Carmine et Fils is a third-generation family business serving Montreal since 1980. We bring decades of experience to outdoor construction, paving stones, landscaping, grading, driveways, stairs, walkways and backyard transformations.

  • Built for structure: We consider slope, soil pressure, base preparation, drainage and wall height before building.
  • Designed for Montreal weather: Our retaining wall projects account for water movement, freeze-thaw stress and seasonal changes.
  • More usable outdoor space: Retaining walls can help turn sloped or uneven areas into cleaner, flatter and more practical spaces.
  • Integrated with the full property: We can connect retaining walls with patios, walkways, stairs, driveways, gardens and backyard paving.
  • Local neighbourhood experience: We serve Montreal, NDG, Hampstead, Côte Saint-Luc, Westmount, DDO, Pierrefonds, Roxboro, Pointe-Claire, Laval and nearby areas.

What’s Included in Our Retaining Wall Services?

Every retaining wall project is different. Some walls are mainly decorative, while others play an important role in holding back soil, managing grade changes or protecting nearby surfaces. We look at your property, slope, drainage, surrounding landscaping and long-term use before recommending the right solution.

Retaining Wall Construction

We build residential retaining walls for backyards, driveways, entrances, garden beds, patios and sloped properties. A properly built retaining wall can help support the land, control elevation changes and create a cleaner outdoor layout.

Backyard Retaining Walls

If your backyard is sloped, uneven or hard to use, a retaining wall can help create flatter areas for patios, seating, gardens, walkways or outdoor living spaces. Retaining walls are often a smart part of a larger backyard landscaping and paving project.

Driveway Retaining Walls

Retaining walls near driveways can help support grade changes, define edges, reduce soil movement and improve the overall look of the entrance. They can also be planned alongside driveway paving and repair.

Garden Walls and Landscape Walls

Low garden walls and landscape walls can help define planting areas, frame outdoor spaces and create cleaner transitions between grass, paving stones, patios and walkways.

Stone Walls and Paving Stone Wall Features

Stone retaining walls and wall systems can give your property a more finished, premium appearance while helping control soil and organize the outdoor layout.

Drainage and Base Preparation

Drainage is one of the most important parts of a retaining wall project. Water pressure behind a wall can cause movement and damage over time if it is not managed properly. We consider base preparation, backfill, slope and water flow before building.

Connections to Stairs, Walkways and Outdoor Surfaces

Retaining walls often work best when planned with the rest of the property. We can coordinate retaining walls with walkway installation, outdoor stairs and steps, backyard landscaping and driveway surfaces.

Homeowners planning retaining wall work should check local requirements, especially for taller walls, walls near property lines, drainage areas, driveways or slopes. You can review municipal information through the City of Montréal. For soil and land-resource information, the Canadian Soil Information Service is a useful Canadian reference. For Quebec climate and freeze-thaw context, Ouranos provides regional climate resources.

Retaining Walls Built for Montreal Properties

Retaining walls in Montreal need to handle more than simple landscaping. The wall has to deal with soil pressure, water movement, winter conditions, freeze-thaw cycles and the way the surrounding outdoor space is used. That is why proper planning matters before the first stone is installed.

In areas like Westmount, Hampstead, Côte Saint-Luc and NDG, retaining walls are often used around older properties, front entrances, gardens, sloped yards and mature landscaping. In DDO, Pierrefonds, Roxboro, Pointe-Claire, Laval and the West Island, retaining walls are often part of larger backyard, driveway, walkway or outdoor living projects.

Carmine et Fils can help you decide whether your property needs a retaining wall, garden wall, landscape wall, grading work or another outdoor solution.

Common Signs You May Need a Retaining Wall

If your property has uneven ground, soil movement or drainage problems, a retaining wall may help protect the space and make it easier to use.

  • Soil washing away after rain
  • A sloped backyard that is difficult to use
  • Garden beds or landscaping that keep shifting
  • Grade changes near a driveway, walkway, patio or entrance
  • Water moving through areas where it causes damage
  • Existing retaining walls that are leaning, cracked or failing
  • A need to create flatter, cleaner or more organized outdoor areas

If these issues sound familiar, it may be time to request an estimate from a retaining wall contractor in Montreal.

You may need a retaining wall if your backyard has a slope, soil movement, drainage problems or uneven areas that make the space hard to use. A retaining wall can help create flatter, cleaner and more functional outdoor areas.

Water pressure behind a retaining wall can cause shifting, leaning or damage over time. Proper drainage, backfill and base preparation help reduce pressure and improve the wall’s long-term performance.
