At Dryshield, we deliver industry-leading waterproofing solutions built for Toronto’s demanding conditions. With over 25 years of experience, we’re trusted by thousands of homeowners to stop leaks, seal cracks, and keep basements dry year-round.
When Is the Right Time to Waterproof Your Foundation?
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 structural 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.
What Should You Know Before Starting Foundation Waterproofing?
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 damage.
- 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.
How to Prepare Your Foundation Surface for Waterproofing
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. Structural 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.

What are the long-term benefits of waterproofing a foundation?
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 Structural 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.

Foundation waterproofing can be done through interior or exterior methods. Exterior waterproofing involves excavating around the foundation, applying a waterproof membrane, dimple board, installing weeping tile, and backfilling with proper drainage material. Interior waterproofing consists of installing a drainage system with a membrane on the walls and connecting to a sump pump or other drainage. The best approach depends on the foundation condition and water intrusion, where internal drainage systems are best used for ground water coming up from underneath the floor and external waterproofing is best for water coming through the walls.
High-quality foundation waterproofing for both internal and external waterproofing will typically last the life of the foundation when the right materials and procedures are used. It is important to consult with a trained professional basement foundation specialist when deciding what solutions to choose.
Yes, an existing concrete slab can be waterproofed using sealants, waterproof membranes, or epoxy coatings. If water is seeping through from underneath the floor, an interior drainage system may be necessary to manage moisture effectively. In cases of severe water intrusion from the foundation walls, exterior excavation and waterproofing may be required for a long-term solution.
