On the Oak Ridges Moraine, drainage makes or breaks a Richmond Hill lot — we slope to the catch basins and build a surface tolerance that won't pond, with the base and depth set for the real traffic the site carries.
We phase the work to keep your Yonge-corridor plaza or office lot open, run after-hours where needed, and finish the curbs and catch basins to spec. $5M insured, in-house crews, and the schedule we keep.
Along the Yonge and Major Mackenzie corridors we plan around retail hours and winter snow-storage needs, build the lot to shed water off the Moraine grade, and finish the curbs and catch basins a Richmond Hill site needs to drain properly through the winter.
We handle commercial & parking lots across Richmond Hill — including Oak Ridges, Mill Pond, Bayview Hill, Jefferson, and Observatory, and the streets and properties around the David Dunlap Observatory, Mill Pond Park, and Lake Wilcox.
