Waterproofing Solutions for Basements in Lethbridge

A dry and moisture-free basement is crucial for maintaining the overall structural integrity and comfort of your home in Lethbridge. As foundation specialists, we understand the significance of implementing effective waterproofing techniques to protect your property from potential water damage. The consequences of an inadequately waterproofed basement extend beyond mere discomfort – dampness can lead to severe problems, such as mould growth, wood rot, compromised insulation, and expensive structural repairs. This is why we are committed to sharing valuable, intent-driven content to help Lethbridge homeowners gain in-depth knowledge about basement waterproofing and guide them in selecting the most suitable solutions for their property.

In this article, we will explore various basement waterproofing methods and discuss their benefits and drawbacks to provide homeowners with a comprehensive understanding of the available options. From discussing foundational principles, such as surface and subsurface drainage systems to more advanced techniques like waterproof membranes and sump pump installations, our goal is to empower homeowners with the knowledge they need to make informed decisions to protect their basements from moisture-related issues.

Understanding the Causes of Basement Moisture

Before diving into various waterproofing solutions, it's essential to pinpoint the causes of moisture accumulation in your basement. Identifying the root cause of moisture issues can help you implement the most effective waterproofing strategy. Common sources of basement moisture include:

1. Groundwater: Rainwater or melting snow can seep into your basement, especially if the surrounding soil cannot effectively drain away the water.

2. Hydrostatic Pressure: Water trapped in saturated soils can exert hydrostatic pressure on the foundation walls, causing water to infiltrate through cracks and pores in the concrete.

3. Condensation: High humidity levels and temperature fluctuations can contribute to condensation build-up on basement walls and floors.

4. Plumbing Leaks: Broken or leaking pipes can also cause moisture problems in your basement.

Surface and Subsurface Drainage Systems

Effective surface and subsurface drainage systems are fundamental in keeping basements dry. By directing water away from your home's foundation, these systems help protect against moisture infiltration.

1. Surface Drainage: Surface drainage systems, such as gutters and downspouts, help collect rainwater and direct it away from the foundation. Ensure that your gutter system is free from debris and that downspouts extend at least 6 feet away from your home.

2. Subsurface Drainage: Also known as a footing or French drain, a subsurface drainage system collects groundwater and directs it away from the foundation. This system usually consists of perforated pipes installed around the foundation perimeter at footing level and covered with gravel.

Waterproof Membranes and Coatings

Waterproof membranes or coatings are an essential component of an effective basement waterproofing solution. These materials create a barrier against moisture, sealing off potential entry points for water.

1. Liquid Waterproof Coating: Applied to the exterior of basement walls, liquid waterproof coatings create a continuous waterproof barrier. These coatings typically consist of asphalt-based, elastomeric, or bituminous materials.

2. Cementitious Waterproof Coating: These cement-based coatings adhere well to concrete surfaces, providing a durable and waterproof barrier. Cementitious coatings can be applied to both interior and exterior basement walls.

3. Sheet Waterproof Membrane: Made from materials like rubber or plastic, sheet membranes are applied to the exterior surfaces of basement walls. They provide a robust barrier against moisture infiltration, with exceptional resistance to hydrostatic pressure.

Sump Pump Systems

A sump pump system is a critical component of comprehensive basement waterproofing solutions, particularly in areas prone to high groundwater levels or frequent flooding. Sump pumps collect water from the basement or crawl space and pump it out and away from your home.

1. Primary Sump Pump: A primary sump pump is a crucial line of defence against basement flooding. These pumps are designed to handle high water volumes and will automatically activate when the water in the sump pit reaches a certain level.

2. Battery-Operated Backup Sump Pump: A battery-operated backup sump pump can provide added protection during power outages or when the primary sump pump fails. These pumps are designed to supplement the primary pump, ensuring continuous operation and safeguarding your basement from flooding.

Crack Repair and Sealing

Effective waterproofing also involves repairing and sealing any foundation cracks, joints, and gaps that can serve as entry points for water.

1. Epoxy or Polyurethane Injection: Epoxy or polyurethane injections are used to seal and repair non-structural cracks in the foundation walls. These materials not only seal out moisture but also help strengthen the concrete.

2. Expansion Joint Sealant: Sealing joint gaps in the foundation prevents water ingress and keeps your basement dry. High-quality, flexible sealants can accommodate slight foundation movements without compromising their effectiveness.


Effectively waterproofing your basement is crucial to maintaining a healthy, comfortable, and safe living environment in your Lethbridge home. By addressing the root causes of moisture issues and implementing tailored waterproofing solutions, you safeguard your property from water damage and costly repairs. 

Taking a proactive approach to basement waterproofing, including installing proper drainage systems, applying waterproof coatings or membranes, and investing in a reliable sump pump system, can make a significant difference in maintaining a dry and secure basement.
