The Orillia build context.
Orillia is a city that notices when work is done right — and notices, even more, when it isn't. Heritage homes, Couchiching waterfront, a downtown that takes pride in how things look. If you live here, you've probably already seen what bad landscaping does to a beautiful property. We're here to make sure that's not what happens to yours.
The terrain
Lake Couchiching and Lake Simcoe shoreline plus mature urban neighbourhoods. Older homes mean older drainage systems that need careful integration with new hardscape.
The soil profile
Lake-influenced clay loam common across the city, with sandy pockets near the shoreline. Older established neighbourhoods often have surprise utility runs that excavation must respect.
Common project types we build here
- Heritage home walkway and step restorations
- Couchiching shoreline patios
- Downtown courtyard redesigns
- Modern decks for waterfront cottages

Why our retaining walls lasts.
A leaning retaining wall is the most expensive mistake we see in this industry. Once a wall tips, it has to come out — every stone of it — and start over. The walls that fail above three feet are almost always the ones built without geogrid. We install geogrid on every single wall, full stop. Not because the engineering code requires it. Because we don't want to be the contractor in your inbox five years from now apologizing.
Quick answers about
retaining walls in Orillia.
Do I need a permit for my retaining wall?
In most Simcoe County municipalities, walls under 3 feet do not need a permit. Walls over 3 feet require an engineered drawing and building permit. We handle both processes.
What is geogrid and why does it matter?
Geogrid is high-tensile mesh that ties wall units back into the earth in horizontal layers. It's what keeps a tall wall from rotating forward over time. Walls without it lean by 18 months.
What's the lifespan of an engineered retaining wall?
Properly built (engineered base, geogrid, drainage, clear stone backfill), expect 40–50 years of structural life. The pavers above the wall will fail before the wall does.
Can you tier a tall slope?
Yes — tiered walls (two or three 3-foot walls with planted terraces between them) are often more cost-effective than one 8-foot wall, and they look better. We design both.
Trusted across Simcoe County.
"Yorkis and the team built our backyard patio in Innisfil and the difference is night and day. The level of detail in the base prep — they showed me photos at every stage — gave us complete confidence. Two winters in, perfectly flat."
"We got three quotes for our retaining wall. Golden Maple wasn't the cheapest but they were the only ones who explained geogrid and showed us the engineered drawing. The wall is gorgeous and rock solid."
"The 3D rendering Yorkis sent us before construction matched the finished backyard almost exactly. No surprises, no scope changes mid-build, fixed price held the whole way through. Rare in this industry."
