Walls that hold
for generations.
A retaining wall is one of those things you don't think about — until it starts to lean. We've spent years rebuilding walls other contractors put up without geogrid, without proper drainage, without an engineering plan. We're not interested in being the next chapter of that story. We build walls the way they should be built the first time, so the slope you've been ignoring becomes the feature your property is known for. Structural projects start at $20,000.
Built to hold back time.
Drainage Systems
We install perforated drainage pipes and clear stone backfill to prevent hydrostatic pressure buildup.
Base Engineering
A minimum 12-inch compacted aggregate base ensures the wall remains level for decades.
Geogrid Reinforcement
For taller walls, we use high-strength geogrid to tie the wall into the soil for maximum stability.
Precision Leveling
Every block is laser-leveled to ensure architectural perfection and structural balance.

"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."
