Exterior basement waterproofing is your first line of defense against water intrusion. It prevents water from entering your home by addressing issues outside the foundation. This method is particularly important for canadian homes exposed to heavy rains, snowmelt, and shifting soil.
Exterior waterproofing is the most effective way to protect your home from long-term water damage
Our advanced exterior waterproofing system creates a watertight barrier around your foundation:
Excavation
We carefully excavate the soil around your foundation to expose the walls and assess their condition.
Foundation Repairs
Cracks and weak points in the foundation are repaired with industrial-strength epoxy or hydraulic cement to restore structural integrity.
Waterproof Membranes and Drainage Boards
High-performance waterproof membranes are applied to the foundation walls, creating a durable, watertight barrier.
Weeping Tile Installation
Weeping tiles (French drains) are installed at the base of the foundation to collect and redirect water safely away from your home.
Exterior basement waterproofing is your home’s first line of defense, and at McDowell Drain & Waterproofing, we’ve redefined the process with advanced materials and superior craftsmanship. While others rely on basic methods, we use an integrated system of high-performance drainage solutions, membranes, and foundation reinforcements to provide an unmatched level of protection.

Sara Swayze
Professional from first contact to job completion. Job was to install a sewer backwater valve but once the floor was opened, it was evident that a sump pump installation was also required. Quickly pivoted to accommodate the additional work scope and still meet the timeline completion. Stuart, the owner is knowledgeable, professional and puts you at ease. Alex the installer did great work and paid attention to details. He was always receptive to any questions or concerns. Would not hesitate to recommend them for your plumbing needs.
