Basement Waterproofing Toronto
We provide quality wet basement leak repairs & waterproofing solutions in Toronto & GTA.
1: Joint Seepage
One of the most common types of water seepage is from JOINTS, where a ‘cold joint’ has been created when two concrete pours happened at different times (i.e. where the foundation wall meets the floor). This can create a situation where weakness in the seal can be compromised.
2: Step Wall Cracks
The natural expansion and contraction of cement in concrete block walls can often lead to step cracks that, if untreated, will lead to leakage. Always have step wall cracks inspected to determine the risk they present.
3: Hydrostatic Pressure
When the ground surrounding your home becomes saturated with water it will put pressure on your foundation walls and beneath your basement floor. Without proper drainage, this pressure can form cracks in your foundation that lead to water entry. This is why proper water drainage away from the foundation is essential.
4: Clogged Footing Drains
Clogged Footing Drains around your foundation, the Weeping Tile System, is a leading cause of water problems because it contributes to hydrostatic pressure. Without proper drainage, hydrostatic (water) pressure builds, creating leaks.
5: Window Wells
Ensure any window wells are clear of debris, such as sticks and leaves, so water drains properly away from the foundation. If you notice water pooling in your window wells, this is a sign that the drains are clogged.
6: Fireplace Leakage
Fireplaces can settle over time, possibly pulling away from the home and leaving cracks where water can enter. Have your basement fireplaces inspected if you suspect a problem or if they are very old.
Ensure your exterior piping has proper caulking and sealants because these seals can degrade over time and create an entry point for water.
8: Foundation Cracks
As foundations settle over time, you may notice horizontal or vertical cracks. These pose potential structural issues to the foundation, so they must be evaluated by a professional, like Stay Dry Basement Waterproofing, to determine the level of risk.
9: Form Ties
Form ties are the steel rods that hold the foundation wall forms together during the concrete pour. The extra ends get broken off after the concrete has set. Water can leak through tie rods, creating small circle stains.
10: Top of Foundation
If ground water pools near the outside of the foundation wall, it can flow over the top edge. Groundwater can also run down the outside to the foundation wall and combine with below grade water to cause excessive leaking.
Causes of Wet & Leaky Basements
Wet basements are usually caused by excess water, often from heavy rain, flooding or melted snow that gets through your home’s foundation cracks or openings. If left untreated, water leaking into your basement can lead to structural damage of your foundation and basement walls.
Regardless of how you use your basement space, wet basements need to be addressed as soon as possible or a variety of problems can cause structural deterioration and possibly mold growth that will reduce the overall value of your home.

Exterior Basement Waterproofing
Water leakage is serious, keeping water away from your exterior walls ensures it will not accumulate around your foundation. Below are key elements of exterior waterproofing.
- Ensure that the grade, or slope, of your exterior landscaping drains water away from the foundation and is not sloped towards the foundation
- Drainage pipes and downspouts should be attached on all sides of the house and sloped away from the home. Ensure these are properly attached and not blocked with leaves or debris
- Ensure that any added soil is sloped away from the home and not creating a downhill slope towards the exterior walls
- Downspouts are not always enough to ensure that the water coming out of your downspouts doesn’t stop and roll back towards the house. Consider downspout extenders or re-grading if this is the case.
Water leakage is serious and keeping water away from your exterior walls ensures it will not accumulate around your foundation. To the right are key elements for exterior waterproofing.
- Ensure that the grade, or slope, of your exterior landscaping, drains water away from the foundation and is not sloped towards the foundation.
- Soil close to the foundation must slope away from the home and not create a downhill slope towards the exterior foundation walls.
- Drainage pipes and downspouts should be attached on all sides of the house and slope away from your home. Ensure these are attached properly and not blocked with leaves or debris.
- Downspouts are not always enough on their own. Consider downspout extenders where needed.
After excavation (the foundation wall is exposed) our Toronto basement waterproofing experts clean and inspect for any cracks and deterioration, which are then sealed and covered with a waterproofing membrane, either Aqua Block or Blue Skin. A new drainage system is added (weeping tiles and dimple board) then tested for proper drainage. While this method will disturb the area around the exterior of your home during repair, it is the best solution for identifying cracks, deterioration on the foundation, basement leak and any other source of exterior water penetration.
Professional Tip: Exterior basement waterproofing is the only method that will stop further foundation wall structural breakdown.
Interior Basement Waterproofing
Interior systems can be part of the leaky basement waterproofing solution if the home or building is prone to water seepage problems. This method of waterproofing is also recommended for homeowners who do not have access to their exterior foundation wall.
Working in tandem with exterior waterproofing systems, interior drainage systems keep water levels from rising above the basement floor. Sump wells are used to collect water that is pumped out and away from the home, keeping your basement dry. These interior basement waterproofing systems can be installed along the perimeter of the interior walls of your home’s foundation. Interior drainage systems are perfect for homes that are surrounded by high water tables or have frequent wet basement issues.
With the installation of materials such as drip moldings, wall vapor barriers, and retarders, the unwanted water is collected and then drained to a sump pump, which pumps the water out of the basement. A battery backup system is installed to provide coverage during any power outage situations.
Window Well Repairs
Window wells are vulnerable entry points for water into your basement because they are below ground level. Installing a window well drain is essential to keeping basements dry and properly protected. Without drains, your window wells can overflow with only one place for the water to go: into your basement. Proper window well maintenance is essential to avoid flooding in your basement. Make sure your window wells are free from sticks, debris, leaves and mud buildup in order to prevent water overflow issues.
Weeping Tile Systems
Weeping Tiles, also known as footing drains, are an efficient solution to collect water. These systems are installed on the exterior of your foundation, and sometimes along the interior of your basement walls. Both systems collect water and move it away from your home. Installing exterior weeping tile systems requires excavation around your home’s foundation. Interior weeping tile systems require cutting into your basement floor in order to drain excess water from your basement, usually to a sump pump pit.
Mold & Air Quality
Mold is an extremely common problem found in basements because the main ingredient is water or moisture. The presence of moisture means that the risk of mold growth is high. Mold is dangerous for all human respiratory systems because mold is a fungus that will release dangerous spores into the air that can affect lungs, skin and allergies. Mold can also cause damage to the structure of your home because it can eat through the surfaces it grows on, including basement walls, drywall and insulation.
If you find a white substance on your concrete basement floor or walls, it may be efflorescence, which forms when water on the opposite side of the wall or underside of the floor evaporates. It leaves behind minerals that form crystals or efflorescence. Finding this white substance in your basement usually indicates moisture. While not always a pressing issue, if the efflorescence is constantly appearing, it is wise to inspect the foundation walls or floor where it is present.
Toronto Basement Waterproofing and Repair FAQs
How can I find out whether I have a leaky basement?
Examine the walls and the floor of your basement. If the floor is wet or you see moist spots on the walls, you’ll know you have a leaky basement problem. Even if you don’t see moisture or water, but you feel a musty smell, or you notice cracks and peeling paint, you may suspect a waterproofing issue. Your next step would be to get a wet & leaky basement inspection done in order to pin point the exact issue.
How does the water pass through the joints between the walls and the floor or through the floor?
The footings of a building are surrounded by a drain tiles system which prevents water from getting in touch with the foundation wall. This drain tiles system helps to waterproof the house. If your home doesn’t have a drain tile system (or it has a faulty one), hydrostatic pressure will push the water against the floor, enabling it to pass through. The latest building codes don’t allow the draining of water from such systems into the public sewers.
One of the most commonly used methods for wet basement waterproofing in Toronto is to use sump pumps to remove water and to direct it to a place away from the walls of the building. Provided that there’s nothing wrong with the sump pump, chances are that a faulty drain tile system is the culprit for leaks.
Are there things that may worsen an already existing leaky basement situation?
It is natural for buildings to shift and settle as they get older. When these movements occur on a leaky basement problem background, they can worsen the situation. If your home is built on a lower level than its immediate surroundings, water will naturally flow towards it and saturate the soil around the foundation. If your drainage system is faulty, the water will soften the soil around your house, making it weaker. Also, if someone installs a swimming pool nearby your house, this may affect your basement system.
What could be the source of leaks from over the top of a wall?
The two main below-grade sources of such leaks are either the improper preformation of the soil grade or the building of the dirt level higher than the concrete wall. In such situations, there’s seepage through the siding or the below-grade brick.
The wrong caulking or tuckpointing of the siding is another cause of above-grade water leaks. Just imagine water leaking along a shower curtain hanging out on the outer side of the ledge. Similarly, moisture that works its way through the veneer of the foundation penetrate and runs along the backside of finishing materials, wreaking havoc on the sill-place joint. Also, improperly directed downspouts that direct the water too close to the foundation may result in leaks, as a consequence of the soil becoming too saturated with water.
The best way to identify whether you’re dealing with an above-grade or below-grade foundation problem is to saturate the soil at the foundation. If you find water in your basement, you can rest assured you’re dealing with a below-grade problem. You’ll need to correct the grading to get rid of this water problem. If there’s no water in the basement, you’re facing an above-grade problem, and you’ll have to sort it out by repairing the waterproofing of your foundation.
Remember that stone, block or tile foundations need specific waterproofing systems. To do things the right way, you’d better reach out to a professional foundation waterproofing consultant to seek advice. Also, if you have this problem with a poured concrete foundation, you’d need to ask an expert for advice. Most companies that sell waterproofing systems have trained and experienced staff, and they can help you address these issues.
Are there things I can do to fix the problem by myself?
Fixing a leaky basement isn’t a DIY job, so we’d strongly recommend that you hire professional foundation leak waterproofers to do it. We have a team of skilled and experienced technicians who have knowledge, experience, tools and the means to analyze the problem and to apply the best basement water seepage solution.
