Basement Waterproofing Services in Ottawa
Keep Your Basement Dry and Protect Your Home’s Foundation
ProCore Foundations provides professional basement waterproofing for homeowners throughout Ottawa. From foundation cracks and drainage problems to recurring basement leaks, we identify the source of the water before recommending a solution.
Our interior and exterior waterproofing services are designed to control water intrusion, protect your foundation and provide lasting protection based on the conditions at your home.
Protect Your Home with Professional Basement Waterproofing
Water entering a basement can damage drywall, flooring and finished spaces while creating damp conditions that contribute to mould and mildew growth. Over time, ongoing water problems can also affect foundation materials and lead to more extensive repairs.
Effective waterproofing addresses how water is reaching your basement rather than simply treating visible moisture. Depending on the cause, that may involve interior drainage, exterior waterproofing, foundation crack repair or improvements around vulnerable openings.
The result is better protection for your foundation, indoor environment, finished basement and long-term property value.
Signs Your Basement May Need Waterproofing
Basement water problems do not always begin with flooding. Watch for:
- Water stains on basement walls
- Damp or musty odours
- Efflorescence (white mineral deposits)
- Foundation cracks
- Standing or pooling water
- Peeling or bubbling paint
- Mould or mildew growth
- Persistent high humidity
- Wet carpet or flooring
- Water after heavy rain or snowmelt
An inspection can determine where the moisture is coming from and what needs to be corrected.
What Causes Basement Water Problems in Ottawa?
Ottawa’s seasonal conditions can be demanding on foundations and drainage systems. Repeated freeze-thaw cycles can affect surrounding soil and existing foundation cracks, while heavy rainfall and spring snowmelt can saturate the ground around a home.
As the soil becomes saturated, hydrostatic pressure can push water against foundation walls and beneath basement floors. Poor grading, clogged or deteriorated weeping tile, inadequate drainage and foundation cracks can give that water a pathway inside.
Older foundations and local groundwater conditions can add to these challenges. That is why the first step is to identify how water is reaching the basement rather than choose a waterproofing product.
Our Basement Waterproofing Solutions
Our Ottawa basement waterproofing services focus on long-lasting protection for your home. We specialize in:
Interior Basement Waterproofing
Interior basement waterproofing systems are designed to manage water that reaches the inside perimeter of the foundation. Depending on the source of the problem, an interior drainage system can collect groundwater or seepage and direct it toward an appropriate drainage point.
Interior waterproofing may be recommended for recurring seepage, groundwater problems or situations where exterior excavation is impractical. The goal is to manage water effectively while helping keep the basement dry and protected.
Exterior Basement Waterproofing
Exterior waterproofing addresses water from outside the foundation. The affected area is excavated so the foundation can be inspected and prepared before waterproofing materials or membranes are installed. Drainage improvements and crack repairs may also be completed as needed.
This approach may be recommended for significant foundation wall leaks, deteriorated exterior waterproofing or situations where long-term protection from exterior moisture is needed.
Weeping Tile Systems
Weeping tile systems help collect groundwater around the foundation and redirect it before water can build up against foundation walls or beneath the basement floor. Depending on the property and the source of the water problem, drainage can be installed or repaired from either the interior or exterior of the foundation.
When an existing system is no longer draining effectively, weeping tile repair or replacement may be recommended.
Sump Pump Systems
Depending on the existing system and water conditions, ProCore can recommend installing or replacing a sump pump as part of a broader basement waterproofing strategy. Battery backup options can provide additional protection if the primary pump loses power during a storm or outage.
A sump pump may be recommended when groundwater needs to be actively collected and discharged, particularly when it works together with an interior drainage or weeping tile system.
Window Wells & Drainage Systems
Proper window wells and drainage help prevent rain and melting snow from collecting around basement windows. Improvements can include better drainage, replacement window wells and covers that limit rain, snow and debris.
Foundation Crack Repair
Where appropriate, cracks can be sealed to help prevent further water entry. If the crack or surrounding foundation shows signs of movement or structural damage, additional structural repair may be recommended.
Interior vs. Exterior Basement Waterproofing
Interior and exterior waterproofing solve different problems.
- Interior waterproofing manages water that reaches the basement and may be appropriate for seepage, groundwater management and properties where exterior excavation is impractical.
- Exterior waterproofing protects the foundation from the outside and may be recommended for significant wall leaks, exterior foundation deterioration or situations where excavation is feasible.
The right approach depends on the source of the water, foundation condition, drainage and property access. In some cases, a complete solution may combine multiple waterproofing or drainage methods.

Basement Waterproofing FAQs
What are the primary causes of basement water problems?
Basement water issues in Ottawa and Gatineau usually come from heavy rainfall, melting snow, poor drainage, or foundation cracks. Water infiltration can lead to wet basements, damage drywall and floors, and create foundation problems if not addressed.
How do I know if my basement needs waterproofing?
Signs include dampness, mould growth, musty odours, and visible water stains on basement walls. If your basement starts leaking or you notice moisture inside, professional waterproofing can protect your home’s foundation and keep the basement dry.

Do I need a sump pump?
A sump pump may be recommended when an interior drainage system needs to collect and discharge water away from the foundation. The need for one depends on your existing drainage and water conditions.
Can waterproofing help prevent mould?
Waterproofing can reduce water intrusion and excess moisture that contribute to mould growth. Existing mould may require separate remediation.
