HERITAGE WATERPROOFING IN ROSEDALE
Preserving Toronto's Most Historic & Prestigious Estates Since 1999
ROSEDALE'S COMPLEX WATER CHALLENGES
CENTURY-OLD STONE FOUNDATIONS
Rosedale's 1880s-1920s estates feature rubble stone and early brick foundations requiring specialized preservation techniques that allow walls to "breathe."
RAVINE VALLEY FLOODING
Located in Toronto's ravine system, Rosedale faces severe flooding risk from Moore Park, Vale of Avoca, and Rosedale Valley ravines.
CARRIAGE HOUSES & HISTORIC STRUCTURES
Many properties feature coach houses, servants' quarters, and underground passages requiring coordinated waterproofing strategies.
ROSEDALE VALLEY WATER DYNAMICS
VALLEY CONVERGENCE
Three ravines converge in Rosedale, creating Toronto's highest flood risk zone during major storms
HISTORIC FLOOD PLAIN
Built on former Castle Frank Brook, underground streams still flow beneath many properties
CLAY BOWL EFFECT
Rosedale's clay soil and valley location create a "bowl" that holds water during rain events
