Exterior Waterproofing in North Vancouver
Exterior waterproofing excavates to the footing, prepares the foundation face, and installs membrane plus drainage board so water is managed before it reaches the wall. On North Shore hillside lots, access, retaining walls, and tree roots often shape what a realistic dig looks like - assessment maps that before a trench quote.
Who this is for
- Homes with chronic wall seepage where interior control will not stop the source
- Foundations with failed or missing exterior membrane on accessible walls
- Owners who can accept landscaping and hardscape disruption for a source-side fix
- Lots where grade and runoff clearly load the excavated side of the foundation
Stops water before it reaches the foundation when access and landscaping allow a full dig.
How the work typically runs
- 1
Access and scope map
Confirm which walls need excavation, what sits above the dig path, and how utilities, spoil, protection, and restoration will be handled.
- 2
Excavate and prepare
Soil is removed to the footing where scoped. The foundation face is cleaned and prepared so membrane can bond or seat correctly.
- 3
Membrane and drainage
Waterproof membrane and drainage board go on; footing drain is placed or repaired where the scope calls for it, then backfill begins with attention to grade.
- 4
Restore and walkthrough
The scope should define final grade, restoration, testing, closeout records, maintenance notes, and any provider warranty in writing.
What influences cost
Prices are property-specific. Access, wall length, soil, restoration, and discharge routing vary by property. These factors usually shape a quote:
- Wall length and depth of excavation
- Access for equipment versus hand dig on tight North Shore lots
- Retaining walls, tree roots, and hardscape restoration
- Footing drain condition and discharge routing
- Weather windows during rainy season
Questions about exterior waterproofing
Is exterior waterproofing always required?
No. Some conditions may call for interior drainage, crack work, surface-water changes, or another response. The assessment should connect the proposed method to an observed water path.
Does exterior work require the whole perimeter?
Not automatically. Some scopes address selected walls while others involve broader excavation. The extent should follow the assessment and be stated before pricing is compared.
How does hillside access change the job?
Steep banks, limited side yards, utilities, and retaining structures can change equipment access, sequencing, protection, schedule, and cost. Those assumptions belong in the written scope.
