Interior basement waterproofing is essential for managing water that has already entered your home’s foundation. This solution is ideal for Canadian homes that experience high groundwater levels, heavy rain, or snowmelt, all of which can lead to basement leaks. Without proper waterproofing, you risk:
Interior waterproofing provides an effective, long-lasting way to protect your basement from water damage and maintain a safe, healthy home environment
At McDowell Drain & Waterproofing, we use advanced materials and systems to effectively manage water from the inside:
A trench is installed along the interior perimeter of the basement floor.
Drain tiles collect water seepage and redirect it to a sump pump system.
Installed to remove collected water, sump pumps discharge it safely away from your home.
Our sump pumps feature backup systems to ensure operation during power outages.
Protective membranes and vapor barriers are applied to the interior walls to block moisture and keep the space dry.
Foundation cracks are sealed with industrial-grade epoxy or polyurethane injections to stop leaks and prevent further structural damage.
At McDowell Drain & Waterproofing, we go beyond traditional interior waterproofing by integrating advanced systems that not only stop water but also enhance the durability of your home’s foundation. Our process ensures that water is efficiently managed and redirected, creating a dry, safe, and mold-free environment.
We install advanced perimeter drain tiles along the interior walls of your basement, designed to capture and redirect any water seepage.
Our sump pumps are equipped with advanced features such as backup power systems to ensure consistent performance, even during power outages.

We had some drainage issues and called McDowell Drain & Waterproofing. It was GREAT service, he called me right back and was here within 2 hours. Solved the problem and haven’t had any issues since. On top of great service, Stuart was very friendly, helpful and knowledgeable! I would highly recommend and will certainly be calling him for any plumbing issues we may have in the future!:)

Professional from first contact to job completion. Job was to install a sewer backwater valve but once the floor was opened, it was evident that a sump pump installation was also required. Quickly pivoted to accommodate the additional work scope and still meet the timeline completion. Stuart, the owner is knowledgeable, professional and puts you at ease. Alex the installer did great work and paid attention to details. He was always receptive to any questions or concerns. Would not hesitate to recommend them for your plumbing needs.
