Foundation excavation
The affected wall is safely exposed to the required depth with utilities, structures, access and soil handling planned in advance.
Membranes, footing drains & exterior repair
Exterior foundation waterproofing and excavation in Greater Burlington
Exterior waterproofing exposes the outside of the foundation so cracks, deteriorated masonry, failed coatings and drainage can be repaired before water reaches the basement. It is often the most direct approach for a known exterior wall problem when access, depth and site conditions make excavation practical.

Repairs and systems
Work we provide.
Depending on the property, the project may use one of these repairs or combine several into a complete system.
Wall and crack repair
Open cracks, mortar joints, penetrations and damaged wall areas are repaired before the waterproof layer is applied.
Waterproof membrane
A compatible exterior membrane creates a continuous barrier across the prepared foundation wall.
Drainage and protection board
A protective drainage layer moves water downward while shielding the membrane during backfill.
Footing drain replacement
Drain pipe, stone, filter fabric and a reliable outlet are installed or repaired at the base of the wall when needed.
Backfill and grading
The excavation is backfilled and the surface is shaped so rainfall continues away from the home.

Your estimate
What is included in the plan.
Access
Porches, driveways, utilities, neighboring property and steep grades can make full excavation impractical or change the equipment required.
Wall preparation
A membrane depends on a sound, properly prepared wall. Loose mortar and deteriorated masonry must be addressed first.
Drain destination
New drain pipe is only useful when it has a legal, maintainable outlet that will not send water back toward the home.
Surface restoration
The estimate should state what happens to lawns, plantings, walks, decks and other disturbed areas.
Already have an estimate?
Compare the complete exterior foundation waterproofing scope.
If Northern Basement Systems, Twin State Basements, 802 Waterproofing or another company has already inspected the property, request a separate estimate and compare quantities, materials, restoration, maintenance, warranty and price.
Common questions
Exterior Foundation Waterproofing FAQs
These answers cover the questions homeowners ask most often. Your inspection and written estimate will address the conditions at your home.
Is exterior waterproofing always better than an interior drain?
No. It blocks or drains water outside, but excavation may be unnecessary, inaccessible or disproportionately disruptive. The better choice depends on the actual entry path, wall condition, access and goals for the space.
How long does exterior waterproofing last?
Service life depends on preparation, materials, drainage, backfill and future site conditions. The proposal should identify the membrane system, drainage details, maintenance and written warranty.
Can you waterproof a stone foundation from outside?
Often, but stone and mortar condition determine how the wall is prepared and repaired. Some older walls need careful masonry work and drainage rather than a membrane applied over unstable material.
