How Does Exterior Basement Waterproofing Work?

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.

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.
