Basements are an essential part of many Edmonton homes, providing valuable storage, living space, or even rental suites. However, Edmonton’s fluctuating climate, with its mix of snow, rain, and freezing temperatures, poses a significant risk to basements especially when it comes to water intrusion. That’s why basement waterproofing in Edmonton is not just a luxury; it’s a necessity.In this comprehensive guide, we’ll cover everything you need to know about basement waterproofing in Edmonton from causes and consequences of water leaks to waterproofing solutions, costs, and choosing the right contractor.
Why Basement Waterproofing Matters in Edmonton
Edmonton’s climate presents unique challenges:
- Heavy snowfall in winter that melts quickly in spring.
- Clay-based soil that expands when wet and contracts when dry.
- Sudden rainfall and flash floods in warmer months.
These factors increase hydrostatic pressure around your home’s foundation. Without proper waterproofing, water can seep into your basement through cracks in walls, floors, or poorly sealed window wells.
Key Risks of a Wet Basement:
- Mold and mildew growth – harmful to health.
- Structural damage – weakened foundation and walls.
- Decreased property value – no one wants a leaky basement.
- Damage to stored items and finished areas.
Proactive waterproofing helps prevent these problems and adds long-term value to your home.
Common Causes of Basement Water Leaks
Understanding why your basement leaks is the first step in solving the problem. Common causes include:
1. Poor Drainage Around Foundation
If your yard slopes toward the house or lacks proper drainage, water can collect near the foundation, increasing pressure.
2. Cracks in Foundation Walls or Floors
Over time, concrete can crack due to settling or freezing/thawing cycles, allowing water to seep through.
3. Window Well Leakage
Basement windows below grade level can allow water in if they’re not sealed or drained properly.
4. Clogged or Broken Weeping Tile
Older Edmonton homes often have clay weeping tile, which can clog or collapse, reducing their ability to drain water away from the foundation.
5. Sump Pump Failure
A faulty sump pump will not remove water that accumulates beneath your basement floor, leading to flooding.
Interior vs. Exterior Basement Waterproofing
There are two main types of waterproofing approaches: interior and exterior. The best method often depends on the specific issue and your budget.
Interior Waterproofing
Best for: Minor leaks, controlling moisture, finished basements.
Methods include:
- Installing a vapor barrier or waterproof membrane on interior walls.
- Using drain tiles connected to a sump pump.
- Sealing cracks with epoxy or polyurethane injections.
Pros:
- Less expensive
- Faster installation
- Minimal exterior disruption
Cons:
- Doesn’t stop water from entering foundation walls
- Might be a temporary solution for severe issues
Exterior Waterproofing
Best for: Major leaks, foundation repairs, long-term protection.
Methods include:
- Excavating around the home and applying a waterproof membrane
- Replacing or upgrading weeping tile systems
- Installing drainage boards and gravel backfill
Pros:
- Stops water before it enters your foundation
- More durable, long-lasting
Cons:
- Expensive
- Time-consuming
- Requires digging around the home
