Are you having problems with your basement? Maybe you’ve noticed that the air is always damp, and that mould is sprouting on the walls. Maybe you’ve recently had a flood, and you’re hoping that you don’t have to throw out your furniture and make expensive repairs again. These problems can be solved with waterproofing.
Here at NTL Contracting and Waterproofing, we take water damage seriously. We don’t think anyone should have to live with damp basements, mouldy walls or flooded floors. So, as the top basement waterproofing contractor in Toronto, we can give you the low down on every waterproofing service you could possibly need.
What Is Waterproofing?
Waterproofing is making repairs and improvements to prevent water from penetrating a building’s foundation and causing damage. These repairs and improvements can be made inside and outside of the property, making sure that everything is safe, secure and water-tight. So, what are your options? Here are the ones that we offer to all of our local customers.
Interior Waterproofing: Vapour Barriers
We install vapour barriers behind basement walls. What is a vapour barrier? It’s a foil or plastic material used to block moisture from seeping into the walls and creating problems like dampness, mould, mildew and much more. We can also place a waterproof membrane underneath the floor, before sealing it with a layer of concrete.
Interior Waterproofing: Plumbing
We implement specific plumbing features that keep basements safe and dry. If you’ve dealt with basement flooding in the past because of harsh rainstorms or spring thaw, you should consider getting a sump pump and a backflow valve. Here is what they can do:
- A sump pump is a machine sitting inside a sump basin in the lowest part of your basement. The sump basin collects excess water, and the sump pump redirects that water away from the foundation. It’s perfect for houses that are in low-lying areas and vulnerable to flooding.
- A backflow valve prevents back-up from the municipal wastewater system from entering through your main line during storms. Older neighbourhoods in Toronto have combined sewer systems that can get overwhelmed by heavy rainfall and push overflow into residential plumbing lines. If you live in an older neighbourhood, you may be vulnerable to this type of flooding.
We also do “drainage reinforcement.” This means that we can take a closer look at your internal drain system, to see if there are any cracks, breaks or clogs that will encourage leaks, poor drainage or sewage back-up. Fixing a small problem with your drain could save you from dealing with a big flooding problem in your basement.
Exterior and Interior Waterproofing: Crack Injection
Water can enter your basement through cracks and breaks in the foundation. Using a polyurethane foam, we can seal up these vulnerable spots and stop water from getting inside.
Exterior Waterproofing: Grading
The yard outside can exacerbate your basement’s risk of flooding. If the ground slopes downward toward your home, then more water will be directed to the foundation and into your basement. If the ground slopes downward away from your home, the water will be directed away from the foundation and into the nearby sewer system. This is ideal.
Grading means strategically diverting the soil around your property so that the slope directs water away from the foundation. We can do this for your yard.
What Are the Steps for Waterproofing?
It depends! Here at NTL Contracting and Waterproofing, we offer an extensive list of services, so we can help you with excavating, crack injecting, grading and much more. That’s what sets us apart from our competitors. We can be there every step of the way.
If you’re signing on for all of our waterproofing services, you should prepare for these important steps.
Step 1: Getting a Quote
The first thing that you’ll have to do is contact us to let us know exactly what your basement trouble is. You can get a quote today by filling out our online form. It’s easy, and it’s free. Once you send in your form, you’ll receive an assessment of the services that you could use and an estimate of the costs. Then, you can determine what options work with your budget.
It’s important to remember that waterproofing your basement is an excellent investment. The costs of waterproofing will pale in comparison to the costs of basement flooding and long-term water damage.
Step 2: Surveying the Area
Before any work gets done, we will survey the land. This step helps us prepare for any obstacles that we can encounter during demolition or excavation. For instance, we need to make a note of the locations of pipes and drains so that they don’t get damaged.
Step 3: Demolition & Excavation
We need to get to the root of the problem. We have to get behind the basement walls, under the floor and into the soil. Demolition means that we will have to dismantle parts of the property in order to access the problem areas.

Excavation is the removal of soil — and sometimes underground utilities like pipes and drains — surrounding the property to easily access the foundation. It’s also a necessary step for redistributing soil to grade the yard.
Demolition and excavation are important steps if you’re interested in signing up for basement underpinning services — underpinning is a method of lowering your basement footing so that you increase the size and height of your basement. Underpinning and waterproofing are often projects that go hand in hand.
Step 4: Waterproofing
When the space is finally prepared, the waterproofing can begin. The bare-bones state of the basement will reveal any hidden cracks or breaks in the foundation. We will see these problem areas and fill them, preventing further water intrusion and material erosion.
If you’re planning on adding plumbing features like a sump pump or backwater valve, we will do those next. Underground drain systems can’t be addressed until the area has been excavated.
After completing the crack injections and plumbing installations, we can finish grading the yard to improve the slope.
The last step of waterproofing will be applying the vapour barriers behind the walls and membrane beneath the floor.
Step 5: Concrete
The next step is concrete finishing — this means applying a smooth and level layer of concrete. The concrete layer adds an additional seal to the foundation, stopping water from getting through your walls or floor.
You will also want to undergo this step because it will cover up the mess of excavation and demolition. We will make sure that your basement looks good as new by the time we’re done with it.
Water damage doesn’t have to feel like an unavoidable part of homeownership. With our help, you can waterproof your entire basement. After we’re done, you can rest assured that your house will be safe, dry and damage-free for years to come.
