Basement Waterproofing in Ottawa
A wet basement puts your home, your health, and your property value at risk. The longer moisture goes unaddressed, the more damage it causes and the more expensive it becomes to fix.
At The Foundation Experts Inc., we provide professional basement waterproofing in Ottawa to stop water intrusion at its source and keep your home dry and protected. Whether you are dealing with leaks, flooding, or ongoing humidity issues, we deliver solutions designed to last.
Why Basement Waterproofing Is Important
Basements are naturally vulnerable to water intrusion due to their location below ground level. In Ottawa, seasonal factors such as heavy rainfall, spring snowmelt, and freeze thaw cycles can increase pressure on foundation walls and make water problems more likely over time.
Water can enter through foundation cracks, porous concrete, or failing drainage systems.
One of the most serious consequences of a wet basement is mold growth. Mold thrives in damp environments and can begin forming in as little as 24 to 48 hours, spreading quickly if the moisture issue is not addressed.
Exposure to mold can contribute to:
- Respiratory issues
- Asthma flare ups
- Skin and eye irritation
- Persistent coughing and throat irritation
- Poor indoor air quality throughout the home
Excess moisture can also weaken your foundation, damage interior finishes, and reduce the value of your property.

Our Foundation Waterproofing Steps
Step 1: Identification of Underground Services
Before any work begins, underground utilities such as gas, hydro, water, and communication lines are located to ensure safe excavation.
Step 2: Site Preparation
Access to the foundation is prepared by removing or adjusting landscaping, interlock, or asphalt as required.
Step 3: Excavation
Soil is excavated down to the foundation footing to fully expose the exterior foundation walls.
Step 4: Foundation Cleaning and Repair
The exposed foundation is cleaned and any cracks or defects are repaired to prepare the surface.
Step 5: Air Gap Membrane Installation
A high performance membrane is installed to create a protective barrier and allow water to drain away from the foundation.
Step 6: Weeping Tile Installation
A drainage system is installed at the base of the foundation to direct water away from the structure in accordance with Ontario Building Code requirements.
Step 7: Backfilling
The excavation is backfilled using materials that promote proper drainage and reduce water buildup around the foundation.
Step 8: Restoration
Landscaping and surrounding areas are restored once the waterproofing work is complete.
Step 9: Completion
The system is in place to provide a dry, healthy basement environment and long term protection.
Your basement waterproofing system is designed for long term performance and is backed by a 25 year transferable warranty, providing lasting protection and peace of mind.
FAQs: Basement Waterproofing
The cost depends on the size of the foundation, the extent of the problem, and the method required. Exterior waterproofing is typically more involved than interior solutions, so a proper inspection is needed to provide an accurate estimate.

Common signs include water on the floor, damp or stained walls, musty odors, visible mold, and foundation cracks. These issues usually indicate moisture is already entering the foundation.
In most cases, existing materials need to be removed or repaired before new waterproofing is installed. Applying new systems over failing materials can lead to ongoing issues.
