Retaining Wall Contractors in Laval & Montreal | Groupe Zamco
Retaining walls do two jobs at once: they hold your property together and define how your outdoor space looks. At Groupe Zamco, we design and build retaining walls for homeowners across Laval, Montreal, and Greater Montreal — from low decorative seat walls around a patio to engineered structural walls managing significant grade changes. Every wall we build is designed for Quebec's freeze-thaw climate and built to last decades.
Why Retaining Walls Fail in Quebec — and How We Build Differently
Most retaining wall failures in Greater Montreal come down to one thing: inadequate drainage and base preparation. Water trapped behind a wall freezes, expands, and pushes. Do that for three or four winters and even a well-built wall will shift.
At Groupe Zamco, every retaining wall starts with proper excavation, a compacted granular base, and a drainage layer behind the wall — gravel backfill with a perforated pipe at the footing to direct water away before it builds pressure. We've rebuilt enough failed walls to know exactly what corners other contractors cut. We don't cut them.
Retaining Wall Materials We Work With
As a Techo-Bloc Authorized contractor, we primarily build with Techo-Bloc's retaining wall product line — one of the most proven systems in Quebec for freeze-thaw performance. Popular options include:
Techo-Bloc Libre — a clean, contemporary stacked block ideal for modern properties. Available in charcoal, antique, and sandstone tones.
Techo-Bloc Pisa II & III — the classic choice for Laval backyards. Slightly bevelled face, multiple sizes, works well for curved walls and tiered terracing.
Techo-Bloc Raffinato — large-format, smooth-faced block for a high-end architectural look. Popular on contemporary infill builds and luxury backyards.
Natural stone — for heritage properties or clients who want an organic aesthetic. More labour-intensive but delivers a look no manufactured product can replicate.
Every material choice is made in our Laval showroom with actual samples against your property's existing materials — not from a catalogue on a screen.
What We Build
Structural retaining walls — managing grade changes of 1 to 6+ feet, typically required when levelling a yard for a patio, driveway, or pool installation.
Decorative seat walls — lower walls (12–24 inches) that double as seating around a patio or fire feature. One of the most popular add-ons to a backyard project.
Tiered garden walls — multiple low walls stepping up a slope, creating usable planting beds and eliminating erosion on difficult lots.
Driveway retaining walls — used to manage grade on sloped driveways or to frame an entrance with a clean, architectural edge.
Pool surround walls — structural walls that hold grade around an in-ground pool, often integrated with coping and patio work.
How Much Does a Retaining Wall Cost in Laval?
Retaining wall pricing depends on height, length, material choice, and site conditions. As a general guide:
-
A small decorative seat wall or garden wall starts around $1,500–$5,000
-
A mid-size structural wall (2–3 feet, 20–40 linear feet) typically runs $5,000–$15,000
-
A large structural wall or tiered system (4+ feet, complex drainage, engineered) ranges from $15,000 to $40,000+
