Foundation Waterproofing Toronto & Cost

Foundation waterproofing is the process of stopping water from entering through foundation walls and below-grade structures. The right solution depends on where the water is coming from (through the wall vs up from below the slab), the foundation type, and access to the exterior. Dryshield provides interior and exterior foundation waterproofing solutions in Toronto, including drainage systems, crack injection, and sump pump options.

Investing in foundation waterproofing is one of the smartest ways to protect your home and avoid expensive water damage repairs. DryShield provides foundation waterproofing in Toronto designed for real basement conditions—leaks through foundation walls, moisture buildup, and recurring seepage. With 25+ years of experience, we help homeowners choose the right waterproofing method (interior, exterior, or crack injection) and back qualifying work with a written lifetime warranty.

Waterproofing your foundation isn’t just a reactive step but a proactive investment that protects your biggest asset. Timing is everything, and here are the key moments when foundation waterproofing should be at the top of your list:

• During New Construction: Are you planning a new build? Now is the perfect time to implement a high-quality waterproofing system. We can integrate superior materials and techniques during construction for maximum durability.

• When You Notice Leaks or Dampness: A musty smell, visible moisture, or damp basement walls are early warning signs of potential water infiltration. Don’t ignore them. Addressing issues early can prevent severe leaks damage.
  

• After Major Weather Events: Heavy rains and melting snow can put immense pressure on your foundation. Waterproofing after such events helps prevent future seepage or cracks caused by hydrostatic pressure.

• Before Basement Finishing: Planning to transform your basement into a living or recreational space? Waterproofing ensures your investment remains protected from leaks and mould growth.
  
• When Landscaping or Drainage Changes Are Made: Changes in your lot’s grading, garden beds, or retaining walls can redirect water toward your foundation. Waterproofing counters this by creating a reliable moisture barrier.
  

We thoroughly assess the exact timing and type of waterproofing your foundation needs. With free inspections and honest recommendations, we help you take timely action before minor issues become costly repairs.

Understanding your options and what to expect can help you make confident, informed decisions about your Foundation Waterproofing Toronto project.

Types of Foundation Waterproofing:

• Exterior Waterproofing: We excavate around the foundation to apply a waterproof membrane and install weeping tiles. This seals your home from external moisture and prevents future water seepage.
  
• Interior Waterproofing: Interior systems are great when exterior access is limited or budgets are tight. They control moisture inside using vapour barriers, drainage channels, and sump pumps.
• Crack Injection Repair: Foundation cracks are a common entry point for water. We use high-quality polyurethane or epoxy injections to seal cracks and stop leaks permanently.
• Sump Pumps & Drainage Solutions: Sump pumps help keep basements dry by automatically removing excess groundwater before it causes damage.
  

Each property is unique. That’s why Dryshield offers customized solutions after evaluating your building’s construction, soil conditions, water table, and existing issues.

At DryShield, preparation is key to achieving durable, long-lasting waterproofing results. Here’s how we approach every job:

1. Detailed Site Assessment :

Our specialists start with a comprehensive inspection of your home’s foundation. We look for visible cracks, previous repairs, drainage issues, and signs of water infiltration. This allows us to identify the root cause and recommend a tailored solution.

2. Clearing the Area :

Before excavation or treatment, the surrounding area must be cleared of landscaping features, debris, and obstacles. It ensures safe access to the work zone and prevents accidental damage.

3. Foundation Cleaning :

The foundation wall must be cleaned of all dirt, residue, and loose material. A clean surface ensures the waterproofing membrane bonds correctly for lasting protection.

4. Leaks Repairs :

If any cracks, holes, or deterioration are found in the concrete or blocks, we repair them using industry-leading materials. This strengthens your foundation and prevents moisture penetration.

5. Waterproofing Application :

Depending on the method, we install a waterproof membrane, drainage board, or interior sealant system. When required, we also install sump pumps and weeping tiles to manage water flow effectively.
We always follow strict safety protocols and building code standards to ensure your foundation is ready for long-lasting waterproof protection.

The foundation waterproofing cost in Toronto depends on the method, materials, and size of your foundation. Interior systems, such as weeping tiles and membranes, typically range from $2,000 to $20,000, while exterior excavation and drainage solutions can cost between $3,000 and $30,000. On average, interior work costs $75–$100 per square foot, and exterior work ranges from $100–$250 per square foot.

Waterproofing your foundation is about more than avoiding water; it’s about building long-term resilience and increasing the value of your property.

1. Preserve Leaks Integrity :

Moisture weakens concrete over time, leading to cracks, mould, and even foundation settlement. A properly waterproofed foundation resists deterioration and strengthens the overall structure.

2. Prevent Mold and Mildew :

Damp basements are breeding grounds for harmful mould spores. Waterproofing eliminates these environments and improves indoor air quality, which is especially important for families with allergies or asthma.

3. Protect Interior Finishes :

Planning a finished basement? Waterproofing ensures your drywall, flooring, and furniture stay dry and intact — even in severe weather.

4. Increase Property Value :

A dry, well-maintained basement is a major selling point. Toronto buyers understand the value of a waterproof foundation and usually pay a premium for homes with documented waterproofing.

5. Save Money on Repairs :

Addressing water issues proactively prevents future damage that could cost tens of thousands of dollars and extends the lifespan of your foundation and basement.

6. Lower Energy Costs :

Moisture in basements increases humidity, which can strain HVAC systems. A dry basement improves energy efficiency, lowering utility bills over time.
