Armour stone is one of the strongest and boldest ways to hold back a slope. These are large, single pieces of natural rock that look rugged and last for decades. But their size is exactly why they have to be set right. A poorly placed armour stone wall can lean, shift, or fail, and moving multi-tonne stone to fix it is a serious job.
McCoy builds armour stone walls that hold their line and their grade for the long haul. We assess the slope, plan for drainage behind the wall, and set each stone on a proper base with the right pitch. Whether it is a low garden wall or a tall grade change, we build it to handle Ontario freeze, thaw, and water pressure.
No two McCoy walls are identical. Here are the armour stone builds we do most often across Oakville, Burlington, Mississauga, and Milton homes.
Strong walls that hold back sloped and hillside yards.
Low natural stone walls that frame beds and level space.
Tiered walls that turn a steep slope into usable levels.
Walls that hold grade along driveways and property lines.
Large stone steps and seating built into the wall line.
Rugged stone walls for waterfront grade and erosion control.
A terraced armour stone wall with built-in steps and planting beds, holding a steep backyard grade.
Built-in armour stone steps and seating along the wall line
Integrated low-voltage lighting on walls and steps
Planting beds and terraces built into the grade change
Engineered drainage behind the wall that relieves water pressure

Most armour stone walls take 1 to 3 weeks on-site once we start, depending on size and access. Peak season books 6 to 12 weeks ahead, call early.
Every wall is scoped to the slope, the length and height, the stone size, and site access. There is no flat per foot quoting that misses the real story. Access for large stone and machines is a big factor, so we assess it in person. We build the written estimate after the on-site visit, so the number you see is the number you pay. No surprises, no escalations.
It depends on the length, the height, the stone size, and site access. A low garden wall is far less than a tall terraced wall that needs machines and drainage work. We give you a written estimate after the on-site visit, not a guess over the phone.
Armour stone is large, quarried natural rock, often weighing hundreds of kilos or more per piece. It is used for retaining walls, borders, and bold landscape features. Its size and weight are what make it so strong and long-lasting.
Both work well. Armour stone gives a natural, rugged look and each piece is unique. Block walls give a clean, uniform finish. We walk you through both during the design phase based on your slope, look, and budget.
Yes. Water building up behind any retaining wall is the main cause of failure. We install drainage stone and pipe behind the wall to relieve that pressure, which is why our walls hold up for decades.
Not when it is built right. A proper base, the correct pitch, and drainage behind the wall keep it solid through freeze and thaw. That is why our 3-year warranty covers shifting, settling, and leaning.
Usually yes, because the stone is heavy. We assess access during the on-site visit and plan the build around your property. If access is tight, we plan for it so there are no surprises.
