If you live in Toronto or the GTA, you know that heavy rain and sudden storms can sometimes lead to flooding. This is exactly why checking to see if your home is at risk before this happens puts you at an advantage! Let’s talk about floodplains, how to determine if your home is at risk, and what you can do to protect your basement from flooding. We’ll also discuss how our waterproofing contractors can help with both proactive waterproofing and emergency water damage repairs.
Understanding Flood Plains
First things first, what exactly is a floodplain? A floodplain is a generally flat area of land next to a river or stream. This area is prone to flooding, especially during heavy rainfall or when snow melts rapidly. A floodplain is a flat area next to a river that is prone to flooding because rivers naturally overflow and deposit sediment there over time. They act as natural buffers, absorbing excess water that rivers or streams can’t contain. This means that if your home sits right next to one of them, you’re at high risk to experience flooding should there be heavy rain.
How Floodplains Affect Homeowners
When it rains heavily, the water levels in nearby rivers or streams can rise in the floodplains faster than you imagine, which leads to overflow. As you can imagine, this makes the nightmare of basement flooding more likely, as this excess water can more easily seep into your basement, causing more severe flooding.
Determining Your Home’s Flood Risk
So, how do you find out if your home is in a floodplain? The Toronto and Region Conservation Authority (TRCA) provides excellent resources for homeowners! You can start by checking out their Flood Risk Management page to understand the basics of flood risks.

Using the TRCA Flood Plain Map Viewer
To know for sure if you’re in a safe or a high-risk flood area, use the TRCA Flood Plain Map Viewer. With this tool, you can enter your address and to check if your property is located within a floodplain! It’s a handy, quick, and reliable resource that provides clear visual information about your flood risk so you don’t have to worry about the uncertainty!
Steps to Take If You’re in a Flood Plain
If you discover that your home is in a floodplain, the first thing to do is stay calm. The great thing about this is that you can take proactive steps to protect your home and basement! Here’s what to do:

1. Waterproofing Your Basement
Waterproofing your basement is one of the most effective ways to protect your home from flooding. By waterproofing your basement, you create a barrier that prevents water from entering, keeping your home dry and safe.
2. Waterproofing From The Inside
Waterproofing from the inside means sealing your basement’s interior walls and floors. This process typically includes:
- Applying Sealants: Waterproof sealants are applied to basement walls and floors to prevent water infiltration.
- Installing Vapor Barriers: Vapor barriers are installed on walls to reduce moisture buildup.
- Interior Drainage Systems: These systems collect water that seeps into your basement and direct it to a sump pump.
3. Waterproofing From The Outside
Waterproofing from the outside stops water before it even reaches your basement walls. This method is more exhaustive of time and effort but highly effective. It includes:
- Excavation: The soil around your basement is excavated to access the exterior walls.
- Applying Waterproof Membranes: A waterproof membrane is applied to the exterior walls to prevent water from penetrating.
- Installing Drainage Systems: Exterior drainage systems direct water away from your home, reducing pressure on your basement walls.
4. Installing Sump Pumps
Installing sump pumps is a superhero in waterproofing your home. It removes water that collects in your basement and pumps it away from your home – making it disappear like magic! Installing a sump pump guarantees that any water entering your basement is quickly removed, preventing flooding.
What to Do During a Flood
Despite taking all precautions, sometimes flooding is unavoidable, especially during extreme weather events. If you find your basement flooded, you need to take action as soon as possible.
