Exterior excavation exposed the wall so waterproofing could address the source side of the water entry. Drainage, membrane work, window wells, utilities, and backfill conditions were part of the planning.
The window well was treated as a drainage point, not just a metal frame. Drainage improvements helped reduce pressure around a vulnerable basement opening.
Toronto has more than one kind of drainage problem. The Beaches and High Park often involve older laterals and mature roots; Riverdale, East York, and The Junction can bring clay tile, cast iron, and tight basement access; downtown properties may deal with shared drains or restaurant grease; and Scarborough or North York homes still need clear grading, sump discharge, and reliable private drains.
