Exterior basement waterproofing in Toronto is considered to be the most expensive, but permanent solution to flood prevention.
The process involves digging into the ground around the house which can expose external foundation walls and identify any existing structural damage. Any foundation cracks are then sealed.
Now it’s time to waterproof. A weeping tile is installed around the exterior walls to provide adequate drainage system and divert the running water away from the house. Walls are covered with rubber Bituthene primer and a rubber Bituthene membrane. Waterproofing companies in Toronto like City Wide Group are actually installing additional layer of outside protection – dimpled sheet of drainage membrane (Delta MS).
Part of the exterior waterproofing solutions is to fix all other leaking sources, such as poorly insulated basement windows and building of a proper window wells.
The next important step external waterproofing is the material used for backfill and proper soil grading so it points opposite direction from your house.
