How Does Water Get in the Basement?
It’s not uncommon for a basement to become damp and musty because of water intrusion. However, this is not how your basement should function. Moisture problems can damage building materials, create unhealthy conditions, and weaken your home's foundation over time.
One of the most common causes of basement leaks is hydrostatic pressure. During periods of heavy rain or snowmelt, the soil surrounding the foundation becomes saturated with water. This pressure forces moisture toward the foundation, where it can enter through cracks, joints, or porous materials.
Other common causes of basement water intrusion include:
- Poor grading that directs water toward the home.
- Improperly functioning gutters and downspouts.
- Foundation cracks and wall penetrations.
- Drainage systems that are blocked or ineffective.
How Waterproofing Helps
Basement waterproofing serves as one of the most effective defences against water intrusion. The goal is to prevent moisture from entering the basement while protecting the foundation and surrounding structure.
Depending on the situation, waterproofing may involve one or more of the following methods:
- Interior Sealants: Useful for addressing minor moisture intrusion and providing an additional layer of protection.
- Interior Water Drainage: Redirects water away from the foundation and helps reduce pressure around the structure.
- Exterior Basement Waterproofing: Creates a barrier between the foundation and surrounding soil to help prevent water infiltration.
Waterproofing can help reduce the risk of flooding, mould growth, structural deterioration, and foundation damage. Our technicians will evaluate your basement and foundation to determine the most appropriate solution for your specific needs.
Signs You Have Water Damage
As mentioned above, water in the basement is an all-too-common occurrence. Unfortunately, many homeowners are unaware of the damage developing beneath the surface.
Common warning signs include:
- Growth of mould and mildew.
- A damp or musty smell in the basement.
- Visible cracks in the foundation.
- Deteriorating building materials.
- Stains and discolouration on walls or floors.
- Sinking or uneven floors.
- White powdery residue (efflorescence) on concrete surfaces.
- Peeling paint or bubbling wall finishes.
- Excessive humidity and condensation.
If your basement exhibits any of these warning signs, contact a waterproofing professional before the problem becomes more severe.
