Case Study: Front Walkway and Steps Upgrade in NDG
Case study of a front walkway and steps upgrade in Notre-Dame-de-Grace, Montreal. Cracked concrete replaced with interlock pavers and precast step units.
A front walkway and steps shape how people experience your home. They're the first thing visitors see and touch, and in Montreal, they take a beating from salt, snow, ice, and freeze-thaw cycles. This project in Notre-Dame-de-Grace replaced a deteriorating concrete walkway and shifting entrance steps with a modern interlock paver system designed to handle decades of Montreal weather.
Project: NDG Walkway Redesign Location: Montreal, Notre-Dame-de-Grace Duration: 5 working days Services: Walkway installation, interlock pavers, outdoor steps
The problem
The property is a 1940s cottage, one of the thousands of solid but aging homes that fill NDG's residential streets. The original concrete front walkway had heaved and cracked over the years, creating uneven sections with nearly 2-inch elevation differences between adjacent slabs. These lips were tripping hazards year-round and became ice-coated danger zones in winter.
Water pooling on the uneven surface had no place to drain. After rain or snowmelt, puddles formed in the low spots, froze overnight, and created sheets of ice across the walkway. The homeowner was spreading salt constantly, which accelerated the concrete deterioration further.
The entrance steps had their own problems. The steps had shifted over the years and separated from the front porch by over an inch. This gap widened during freeze-thaw cycles and allowed water to infiltrate behind the steps, accelerating their movement.
The complication: mature trees
A row of mature maple trees along the front of the property had root systems running under the walkway area. These roots had contributed to the heaving of the original concrete and needed careful navigation during excavation. Cutting major roots wasn't an option, since it would have compromised the health of the trees.
The solution
Wider walkway
The original walkway was 30 inches wide, too narrow for comfortable use and below modern standards. We widened the new walkway to 48 inches, providing enough room for two people to walk side by side and for moving furniture or large items to the front door.
The wider walkway required careful planning around the tree roots. We mapped the root locations during initial excavation and adjusted the walkway alignment slightly in two spots to avoid major roots while maintaining a natural-looking path.
Base preparation
After removing the old concrete, we excavated to 12 inches below the finished paver surface. The excavated area received a geotextile membrane followed by compacted crushed limestone (0-3/4 inch) installed in three lifts. Each lift was mechanically compacted before the next.
In the areas near tree roots, we used hand compaction rather than plate compactors to avoid root damage. The base depth was maintained throughout, providing consistent structural support.
Paver installation
We installed Techo-Bloc Blu 60mm pavers in Onyx Black, laid in a running bond pattern. The dark tone complements the grey stone facade of the cottage and provides a crisp, modern contrast to the surrounding green lawn.
Running bond was selected over herringbone because the walkway is a pedestrian-only surface. Running bond provides sufficient structural integrity for foot traffic while creating a clean, linear visual that guides the eye toward the entrance.
Concrete edge restraints were installed along both sides of the walkway and anchored with 10-inch spikes. The restraints prevent lateral creep and maintain the crisp edge line.
Step reconstruction
The three entrance steps were completely rebuilt. We removed the old concrete steps down to the footing and replaced them with Permacon Lafitt Grande precast step units in a charcoal tone that coordinates with the Onyx Black walkway pavers.
The new steps were set on a frost-line footing to prevent the seasonal shifting that plagued the originals. Each step was leveled precisely for consistent rise and run, meeting building code requirements and providing safe, comfortable footing.
The gap between the steps and the porch was eliminated by integrating the step structure with the existing porch foundation. This connection prevents future separation.
Joint finishing
All paver joints were filled with polymeric sand, which locks the pavers together, prevents weed growth between joints, and resists washout from rain and snowmelt.
Navigating tight spaces
NDG's residential lots are small, and front yards leave limited room for equipment access and material staging. For this project, we staged materials on the driveway and front lawn, coordinating delivery timing to minimize the footprint and duration of the staging area.
Excavated material and old concrete were loaded directly into bins for removal, with access through the front of the property. The logistics of working in tight residential spaces are a routine part of project planning for any Montreal neighborhood.
The result
The new walkway and steps changed the entire front of the property. The wider path, level surface, and coordinated dark tones give the 1940s cottage a modern entrance that still fits its architectural character.
More importantly, the tripping hazards and ice pooling are gone. The walkway's base system handles freeze-thaw without heaving. Proper grading moves water off the surface. And the steps sit on a foundation that doesn't shift with the seasons.
The homeowner reported that the project made a visible difference in how visitors experience the home, and eliminated the winter safety concerns that had been a constant worry.
Lessons from this project
Wider is better. A 48-inch walkway costs only marginally more than a 30-inch one (more pavers, more base material) but changes how it feels to walk to your front door. The added width is one of those upgrades people notice every single day.
Tree roots need respect. Working around mature trees requires patience and hand work. Cutting roots to make the project easier leads to tree decline and future problems. Adjusting the design to accommodate the trees preserves property value and neighborhood character.
Steps need footings. Entrance steps that sit on a surface-level base will eventually shift in Montreal's climate. Frost-line footings are the only reliable foundation for steps in Zone 5.
Material coordination matters. The Onyx Black pavers and charcoal step units create a unified entrance. Mismatched materials (different colors, manufacturers, textures) would have produced a patchwork look.
