Basement Waterproofing and Foundation Repair
A damp basement is more than just a nuisance, it can lead to mold growth, weakened foundations, and serious damage to your home’s structure and value. At Mr. Furnace, we provide comprehensive basement waterproofing and foundation repair services for St. Catharines homeowners. Our licensed technicians are trained to identify, stop, and prevent moisture issues before they turn into costly problems. With over 47 years of local experience, we know how to protect your basement from Ontario’s changing weather and rising groundwater levels.
Our Basement Waterproofing & Foundation Repair Process
We follow a transparent and thorough process so you know exactly what’s happening, and why. Here’s how we protect your basement from the ground up:
1
Thorough Assessment: We start with a full inspection of foundation cracks, moisture points, and wall integrity.
3
Interior Water Protection: Where necessary, we install drainage membranes, sump pumps, and weeping tile systems to manage internal water flow.
2
Crack Sealing & Repair: Using industry-grade sealants and injection methods, we seal cracks to block future water intrusion.
4
Foundation Strengthening: If your structure shows signs of shifting or stress, we reinforce the affected areas to restore stability and prevent future settlement.
Waterproofing & Foundation Repair to Protect Your Home
Water doesn’t need an invitation to enter your basement, it finds its way in through porous concrete, expansion cracks, and foundation gaps. In St. Catharines, repeated freeze-thaw cycles intensify the issue. Moisture expands inside cracks, causing them to grow wider with each season. Mr. Furnace offers professional-grade interior waterproofing and structural repair services that:
Foundation Crack Repair
Even small cracks can compromise your foundation over time. We identify all visible and hidden cracks and repair them using polyurethane or epoxy injection systems. This not only seals out moisture but also strengthens the affected concrete, restoring its structural integrity.
Interior Drainage Systems
Water can enter even without visible cracks, hydrostatic pressure and poor soil drainage can push moisture through solid concrete. If water is pooling inside, we install custom drainage systems, including sump pumps and interior weeping tile, to collect and redirect water safely away from your home.
Waterproofing Coatings & Sealants
To protect porous basement walls from dampness, we apply advanced coatings and vapour barriers. These create a water-resistant layer that helps prevent mildew, condensation, and long-term damage caused by consistent indoor humidity or slow water seepage.
Don’t wait for a small leak to become a big problem.
