Protecting your home from water damage is essential—especially in places like Guelph, where heavy rainfall, clay soil, and fluctuating weather patterns can take a toll on your foundation. Exterior basement waterproofing plays a crucial role in maintaining the integrity and value of your property, preventing issues like a wet basement, foundation cracks, and erosion.
At WinStorm Projects, we specialize in custom-built exterior waterproofing solutions tailored to Guelph and surrounding areas. As a leading waterproofing company, we bring years of experience in landscaping, foundation work, and outdoor construction.

Let’s explore the top basement waterproofing methods, materials, and services available—and how to choose the right solution for your home.
Understanding Exterior Basement Waterproofing
Exterior basement waterproofing involves applying moisture-resistant barriers and drainage systems outside your home’s foundation wall. This approach prevents water from ever reaching your basement walls, reducing the risk of basement flooding, structural damage, or long-term foundation issues.

What We Do:
- Apply waterproof membranes and liquid coatings to foundation walls
- Install weeping tiles and French drains for efficient drainage
- Perform foundation crack repair and seal joints
- Regrade landscaping to ensure proper water flow away from the home
Guelph’s unique soil and weather conditions require a comprehensive waterproofing method—not just a surface fix. Our team combines industry best practices with local insight to ensure every waterproofing project stands up to Ontario’s wet seasons.
Proven Waterproofing Methods That Work in Ontario Homes
Here are some of the most effective exterior waterproofing methods used in Guelph and across the Toronto area:
1. Waterproof Membranes & Cementitious Coatings
These coatings form a durable barrier on your foundation wall, resisting basement leaks and hydrostatic pressure. We often use liquid-applied membranes and cementitious coatings for their flexibility and long lifespan.
2. Weeping Tile & French Drain Systems
Installed around the perimeter of the foundation, these drainage systems redirect groundwater away from your home. Especially effective in areas with clay soil, like Guelph, they help prevent both foundation damage and basement flooding.
3. Crack Sealing & Surface Barriers
For homes with visible foundation cracks, we offer targeted crack sealing services using high-grade, flexible sealants. These surface barriers are essential for preventing future water intrusion, especially in aging or settling homes.
Choosing the Right Waterproofing Materials

Material selection plays a huge role in how long your basement waterproofing lasts. Here’s what we recommend:
- Cementitious Coatings: Ideal for rigid surfaces; long-lasting and easy to apply
- Liquid-Applied Membranes: Provide seamless protection for foundations with irregular shapes
- Exterior Sealants: Flexible and effective for sealing fine cracks and seams
- Eco-Friendly Products: Safe for the environment and effective in moisture control
- Weeping Tiles/French Drains: Essential for managing surface and subsurface water
