Armour stone retaining wall terracing a Muskoka lakefront lot

Retaining Walls
in Muskoka.

We build armour stone, dry-stack, and engineered concrete retaining walls to terrace Muskoka lots, stabilize shorelines, and create usable level ground on shield-rock properties.

What's included

The work, in detail.

We build armour stone, dry-stack, and engineered concrete retaining walls to terrace Muskoka lots, stabilize shorelines, and create usable level ground on shield-rock properties.

  • Armour stone walls up to 6 feet
  • Dry-stack landscape walls
  • Engineered concrete walls with drainage
  • MNRF-permitted shoreline stabilization

How we approach retaining walls.

Engineered for the slope

Geotechnical assessment, sealed wall design above height thresholds, and drainage strategy designed before stone is delivered. Walls that move are walls that were skipped engineering.

Armour stone done right

Stone sourced locally, set with a properly compacted base, draining backfill, and geotextile separation. Each stone hand-fit so faces meet without gaps.

Shoreline-permitted

Work below the high water mark requires MNRF, DFO, and municipal review. We prep applications, sequence in-water windows, and coordinate marine equipment.

Drainage is the wall

Every wall is a drainage system that happens to look like stone. Weeped backs, perforated drains, free-draining backfill, and surface water tied to grade.

What's involved

Every trade in a retaining walls project.

We run the full scope or with vetted partners on a single contract. Here's what typically lands inside this kind of project.

Engineering

Stamped designs for any wall over 1.2 m with drainage and geogrid spec.

Excavation

Cut, fill, and base preparation with compacted granular A.

Drainage

Perforated weeping tile and free-draining backfill behind every wall.

Block or stone

Armour stone, segmental block, or natural stone face options.

Steps & landings

Integrated steps, terraces, and pathway tie-ins.

How we meet

We come to you. Lake, city, or screen.

We love meeting people over a coffee so we can hear them out and understand their vision for the cottage. Boots on the ground in Muskoka, in-person meetings in Toronto, or a video call if your schedule is tight. Pick what works for you.

Coffee in the city

Most of our clients live in Toronto or the GTA. We meet downtown between site days so you can sketch ideas, swap photos, and walk through scope without driving north.

Boots on the ground in Muskoka

Our crew lives here. We'll meet you at the cottage, walk the lot, and pull tape on what you're thinking, no appointment shuffling required.

Virtual walkthroughs

Live video walkthroughs of the site, the build, and the selections. Hit join from anywhere in the world and see the project as if you were standing in it.

Year-round or weekenders

Whether the cottage is your full-time home or your getaway, we shape the build sequence around how you actually use the place, and how often you can be on site.

Our process

How a retaining walls project runs.

03

Build

Excavation, base prep, stone placement, and backfill drainage.

FAQ

Common questions.

Do shoreline walls need MNRF approval?+

Any work below the high water mark almost always requires MNRF and municipal approval. We handle the application.

Armour stone, segmental block, or poured concrete?+

Armour stone reads most natural and ages best. Segmental block is faster on small terraces. Poured concrete is for engineered walls above 6 feet or with heavy surcharges.

How tall can a retaining wall go?+

Up to about 3 feet without engineering. Above that, sealed structural drawings are required. We've built engineered armour stone walls to 8 feet.

What does an armour stone wall cost?+

Typically $250 to $500 per linear foot for walls under 4 feet, including excavation, base, drainage, and stone placement.

Will the wall heave in winter?+

Properly built walls don't. Frost-depth base, free-draining backfill, and drainage tied to grade is what stops heave. Heave is always a base or drainage failure.

How long does a wall project take?+

Most residential walls run 2 to 6 weeks on site. Shoreline walls with permits add 3 to 6 months upfront.

Can you terrace a steep cottage lot?+

Yes. Stepped terraces with armour stone or boulder walls create usable level ground on steep shield-rock lots without changing the drainage pattern.

Do you handle the MNRF and DFO applications?+

Yes. We prepare and submit, attend any agency meetings, and coordinate the in-water work window.

What's the difference between dry-stack and mortared walls?+

Dry-stack uses no mortar, drains naturally, and reads traditional. Mortared walls are sealed, used where appearance demands tight joints, and require engineered drainage behind.

Can you tie stone steps into the wall?+

Yes. Hand-set granite or fieldstone steps integrated with the wall, with code-compliant rise and run.
