OUR PROCESS
our project
At Classic Waterproofing & Concrete, we take pride in delivering high-quality waterproofing and concrete solutions across Ontario. Our portfolio highlights our commitment to excellence, attention to detail, and customer satisfaction.
Basement waterproofing is a process that helps to protect your basement from water damage. It involves sealing the foundation and groundwater infiltration points, installing drainage systems, and using polyurethane or rubber membranes to seal any openings in the walls or floors.
A basement can be a great place to store your belongings and enjoy the extra space, but it’s important to protect it from water damage. Many homeowners choose to waterproof their basements using one of several methods, such as using membranes or coatings. When done correctly, this type of waterproofing will help keep your home dry in the event of an unexpected rainstorm or flooding.

Basement waterproofing cost in Ontario depends heavily on method and scope. Here's real 2026 pricing, project totals, and where subsidies can help.
Standard drainage looks fine, but water still gets in during storms. Here's why basement leaks after heavy rain, including one cause most people miss.
Waterproofing is the process of protecting a building from water intrusion. It prevents moisture from entering basements, foundations, and other vulnerable areas. Proper waterproofing protects your property from structural damage, mold growth, and costly repairs caused by water leaks.
Look out for signs like musty odors, damp walls or floors, visible cracks, peeling paint, or water stains. If your basement feels humid or has pooled water after rain, it’s a strong indicator that waterproofing is needed.
Common causes include poor exterior drainage, foundation cracks, hydrostatic pressure (water buildup in the soil), clogged gutters, or aging waterproofing systems. Our team can assess and identify the exact cause during a free inspection.
Exterior waterproofing stops water before it enters your foundation. It involves excavating the foundation, applying waterproof membranes, and installing drainage systems. Interior waterproofing manages water that has already entered, using sump pumps, drainage channels, and vapor barriers to keep your basement dry. Both methods are effective depending on the situation.
Yes! At Classic Waterproofing, we offer workmanship warranties on most of our services to give you peace of mind. We stand behind our solutions and use only high-quality materials built to last.
While DIY solutions like sealants or epoxy kits may offer temporary relief, they usually don’t address the root cause of water intrusion. For long-term protection, it’s best to hire professionals with the right tools, training, and experience.
Project duration depends on the size of the job and the method used. Most interior waterproofing projects take 1–3 days, while exterior systems may take several days to a week. We’ll provide a timeline after assessing your needs.
Absolutely. Waterproofing helps maintain your home’s structural integrity, increases property value, improves air quality, and prevents expensive water damage. It’s one of the smartest upgrades you can make—especially before selling or finishing a basement.
