Basement waterproofing is the process of stopping water from entering a basement by sealing foundation cracks and joints and installing a waterproofing system (interior or exterior) that routes water away from the foundation.
The 3 Core Waterproofing Methods for Toronto Homes:
Exterior Waterproofing: Excavating the foundation to apply a waterproof membrane and replace the weeping tile system.
Interior Water Management: Installing an internal drainage channel (French drain) and sump pump to capture rising groundwater.

The lifespan of basement waterproofing depends on the method used and the quality of installation. Interior waterproofing solutions with sump pumps are lifetime warrantied sump pumps that come with a 2- 3 year manufacturer warranty and can need replacing sooner. Typically industrial cas iron sump pumps will last 5 to 8 years on average depending on how much water is pumped over a period of time. Exterior waterproofing will typically last the lifespan of your foundation if done properly when the highest quality materials are used. However homeowners need to be aware that if water comes up from underneath the floor eternal waterproofing will not protect the foundation from seepage. With professional installation and proper maintenance, most waterproofing solutions will provide lifetime protection. At Dryshield, we only use high-quality materials and expert techniques to ensure a lifetime guaranteed results. We are proud to offer a lifetime guarantee on all our waterproofing services.
A musty smell in your basement typically signals dampness, even if no visible water leaks may be present or mold may be growing if there is high enough relative humidity. An odor is often caused by mold or mildew, which thrive in moist environments and can trigger health problems like asthma and allergies. Dryshield Waterproofing offers effective solutions to eliminate the moisture causing the smell, sealing your basement’s walls and floors and creating a dry, fresh environment.
Exterior waterproofing is the most reliable solution to keep water out of your basement when the water is coming in through the foundation walls. It involves using waterproof membranes to seal the basement walls and keep water from penetrating the concrete. This approach, combined with a French drain system, is highly effective in maintaining a dry basement.
Interior waterproofing includes weeping tiles under the basement floor to route water to a sump pump or drainage. Interior waterproofing is ideal from ground water and is the only way to properly prevent seepage that comes up from under the floor and not through the walls. Both external and interior waterproofing can be just as effective as one another depending on how the seepage is coming into the basement.
Before hiring a basement waterproofing company, it’s important to research and compare different contractors to ensure you find the best option for your needs. When speaking with waterproofing companies, be sure to ask about the written guarantee they offer for their work once the project is complete.
In an industry where some contractors operate out of trucks, having a waterproofing warranty is crucial to ensure your home remains properly protected. Unfortunately, many contractors cannot offer such a guarantee.
At DryShield Waterproofing, we provide a lifetime warranty on our services. We are so confident in the effectiveness of our external waterproofing system that we back our work forever. While some contractors may offer lower prices or faster service, this often comes at the expense of quality. In many cases, homeowners end up spending more time and money to fix poorly done work.
Many contractors mistakenly believe that simply keeping water away from your home is enough for basement waterproofing. The reality is that managing water around your home is essential to maintaining a dry basement, regardless of the amount of water in the soil. Proper drainage systems are key to ensuring that your home remains protected from water infiltration.
