Armour Stone Installation Across Toronto & GTA
OCM designs and installs natural armour stone walls, accents, and decorative features across the GTA. Armour stone gives your property the high-end natural look of a real-stone retaining wall — without the maintenance of modular block. We source quarried Wiarton, Eramosa, and Algonquin limestone, deliver, and place every stone with skid-steer precision.
Types of Armour Stone Projects We Build
- Retaining walls — gravity-stacked armour stone walls up to 8 ft, engineered for engineered slopes.
- Garden borders & landscape accents — smaller stones for raised beds and decorative edging.
- Driveway entry features — bold-stone gateposts and front-yard centerpieces.
- Steps & outdoor stairs — single-stone slab steps in 4-8 ft widths.
- Pool surrounds — natural-stone pool decks with non-slip flamed finish.
- Erosion-control walls for sloping lots and waterfront properties.
- Custom seat-walls and fire-pit surrounds — full-tonne stones double as built-in seating.
Our Armour Stone Installation Process
- Free on-site quote within 24 hours. We measure, photograph, and quote per linear foot or per project.
- Stone selection. We can show you Wiarton, Eramosa, or Algonquin samples at our yard, or pick from photos.
- Site prep & base. Excavate, compact granular base, install drainage stone behind walls.
- Geo-textile install behind retaining walls — prevents soil migration through joints.
- Stone placement with skid-steer and precision rigging — each stone leveled and chinked.
- Cap stones & coping for finished look.
- Backfill, drainage tile, and final landscape grade.

Armour Stone Installation FAQ
How tall can an armour stone retaining wall be?
Walls up to 4 ft typically don’t need an engineer in most GTA municipalities. Walls 4-8 ft usually need an engineered drawing. We handle engineer coordination as part of any wall over 4 ft.
Do armour stone walls need a permit?
Most walls under 1 m don’t need a permit but check your municipality. Vaughan, Markham, Richmond Hill, and Toronto all require a permit for walls 1 m+ tall.
How long does a typical armour stone wall take to build?
A 30 ft x 4 ft tall wall typically takes 3-5 working days from base prep to backfill. Larger projects 1-3 weeks.
Can I see stone samples before deciding?
Yes — we have a small sample yard or we can drop photos by email. We work with Wiarton, Eramosa, and Algonquin limestone primarily.
Do you handle the drainage behind the wall?
Yes — proper drainage is the #1 cause of armour stone wall failure. Every wall we build includes geotextile, 12+ inches of drainage stone, and weeping tile to daylight.
What’s the difference between armour stone and modular block?
Armour stone is real quarried limestone, natural finish, lasts 50+ years, looks high-end. Modular block (Allan Block, Versa-Lok) is engineered concrete, faster install, smaller stones, more uniform look. Armour stone costs more but adds significantly more property value.
