Bélair Aménagement has been building retaining walls in Aylmer since 2011. We work just as comfortably in the mature, wooded yards of Old Aylmer as in the newer developments of the Plateau, Wychwood, Lucerne and Deschênes — two different realities, one same eye for detail.
Most Aylmer lots have a gentle slope or grade change to tame. Here, a wall is almost never just a matter of structure: it has to organize the yard, create usable terraces and, above all, blend into landscaping that's already established. That's why we start from your interlocking pavers, your planting beds and the style of the street before choosing a block or a tone — so the result looks like it was always there.
Full excavation, a compacted crushed-stone footing, geogrid reinforcement where needed, clear stone and a perforated drain behind every wall: the invisible part is done by the book. That's what guarantees an Aylmer wall stands straight for decades, even on a waterfront lot near Deschênes Lake where water forgives nothing.

Retaining walls in Aylmer
Structural retaining walls
When a Plateau or Lucerne lot has a real grade change, we build a wall in architectural block (Techo-Bloc, Permacon) reinforced with geogrid. Strong enough to hold back the soil, refined enough to stay beautiful year after year next to your driveway.
Garden terraces & raised planters
The great classic of Aylmer yards: turning an unusable slope into a series of planted terraces. Raised planters, tiered garden terraces and well-defined zones that showcase your perennials and carry on the spirit of the neighbourhood's mature landscaping.
Natural stone walls
On the large wooded lots of Deschênes or the heritage properties of Old Aylmer, natural stone and armour stone deliver that organic finish that ages gracefully. Each stone is hand-picked and hand-laid for a one-of-a-kind wall, in keeping with the character of the sector.
Integrated stairs & walls
Connect the levels of a sloped yard with a staircase built into the wall and recessed lighting, so you can move around safely after dark. An elegant transition between the paver patio, the garden and the driveway — designed as a single piece.
Drainage & repair
An old Old Aylmer wall that's leaning, or a bank eroding near Deschênes Lake, almost always comes down to poorly managed water. We diagnose the cause and rebuild with clear stone, a perforated drain and a proper foundation, directing water where it needs to go — for stability that lasts.

Assessment & plan
Site visit in Aylmer, reading the slope, the soil and the drainage, matching to your existing pavers, and an engineer's plan if the height requires it.
Excavation & base
Excavation, a compacted crushed-stone footing and a perfectly level first course — the base of every solid wall.
Building & drainage
Laying the blocks or stone, geogrid reinforcement, clear stone and a perforated drain behind the wall to evacuate water — crucial on waterfront lots near Deschênes Lake.
Finishing & backfill
Glued capstones, compacted backfill, grading, planted beds and a complete site cleanup. A finished, clean wall built to last.

"In the 42 years I've owned a home, Bélair Aménagement is probably the best landscaping contractor I've ever dealt with. I hired them to complete work related to an insurance claim caused by a car hitting my front lawn."

Frequently asked questions about retaining walls in Aylmer
How much does a retaining wall cost in Aylmer?
Cost varies by the height of the grade change, the length of the wall and the material chosen. In Aylmer, most residential projects — raised planters, garden terraces or a low entry wall — run between $45 and $90 per square foot of wall face, all included: excavation, compacted base, drainage and installation. A low decorative wall costs considerably less than a structural wall over one metre requiring geogrid. We provide a free, itemized quote after seeing your yard.
Do I need a permit for a retaining wall in Aylmer?
Aylmer is part of the City of Gatineau, so the same regulations apply: a retaining wall 1.2 metres and higher (measured from the bottom of the footing to the top) usually requires a municipal permit and, often, a plan signed by an engineer. Below that height, a permit is normally not required. We handle the process with you and work with engineers whenever the height calls for it.
Can my wall match the interlocking pavers I already have?
That's exactly what most Aylmer homeowners are looking for. Many already have a driveway, patio or steps in interlocking pavers; we choose blocks, capstones and tones that extend that landscaping instead of clashing with it. The result makes the wall, the planters and the pavers look like they were designed together from the start.
I have a waterfront lot near Deschênes Lake: how do you handle water and erosion?
The lower, wetter lots along Deschênes Lake and the Deschênes sector need special attention to runoff. We design the wall with generous clear stone, a perforated drain that discharges to a proper outlet and backfill that directs water away from the house. Done right, the wall stabilizes the bank, slows erosion and holds the soil in place rather than letting it wash downhill.
Do you repair old leaning walls in Old Aylmer?
Yes. Many mature properties in Old Aylmer have old railway-tie or block walls that bulge, sag or tip over. We find the cause — almost always missing drainage or too thin a base — then rebuild with a proper foundation and drainage, in a style that respects the character of the heritage streets. It's best to act before another winter makes the lean worse.
