FAQs
Everything you need to know.
- How much does an armour stone retaining wall cost in North York?
- Armour stone walls typically range from $50–$100+ per linear foot depending on wall height, stone type, and site accessibility. A typical 50-foot wall at 3 feet height ranges from $7,500–$15,000.
- How high can an armour stone wall be built?
- Single-tier walls typically reach 3–4 feet. For taller walls we either create terraced multi-tier designs or work with structural engineers. Permits are required for walls over 1 metre in most Toronto municipalities.
- Is armour stone better than interlocking block?
- Armour stone offers superior longevity (100+ years vs 50 for blocks), zero maintenance, and a natural aesthetic. Interlocking blocks offer more precise lines and are often more cost-effective for mid-sized walls. We help determine the best solution for your site.
- Do armour stone walls need drainage?
- Yes — proper drainage is critical for any retaining wall. We install perforated drainage pipe and clear gravel behind all armour stone walls to prevent hydrostatic pressure buildup.
