Retaining walls & terracing
Tiered walls for driveways, slopes, and yard terraces.

Armour Stone
Stops erosion and holds slopes on waterfront properties through Georgian Bay freeze-thaw cycles.

On Your Property
We build armour stone walls that look right and stay put — proper drainage, a solid base, and stone placed to handle freeze-thaw.
From tight cottage access to open waterfront lots, we plan equipment paths and staging so the finished wall fits the property. When engineers specify modular retaining, we also install Redi-Rock® systems supplied by The Sarjeant Co.

Engineered Option
When engineers or clients specify a modular retaining system, Stuart Thomas Construction installs Redi-Rock® walls supplied by The Sarjeant Co. — with the same drainage planning and finishing standards as our natural armour stone work.
