Exterior Basement Waterproofing
Your home’s structural stability may be threatened and costly repairs may be necessary if your basement sustains water damage. Although interior waterproofing is crucial, external basement waterproofing provides an additional line of defense by keeping water from ever getting to your foundation.
Professional exterior basement waterproofing treatments are available in Ottawa from Francis Home Environment. Our qualified specialists assess your foundation and offer long-lasting fixes to stop leaks, fractures, and expensive water damage.

Our Quick and Simple Exterior Basement Waterproofing Process
Creating waterproof exterior basement walls involves careful excavation and proven installation techniques. Our process includes:

1
Excavation and inspection of the foundation to evaluate existing damage
2
Application of waterproof membranes to seal the foundation walls
3
Installation or repair of weeping tiles to redirect groundwater
4
Enhancement of drainage systems to prevent water pooling
5
Final waterproofing inspection and expert backfilling
The Importance of Exterior Basement Waterproofing
Unlike interior waterproofing, which addresses moisture buildup inside the basement, exterior basement waterproofing works proactively to stop water before it ever reaches your foundation. Without external protection, water can still infiltrate through cracks and gaps, leading to leaks inside the basement.
In addition to preventing leaks, exterior waterproofing also helps safeguard your foundation by reducing hydrostatic pressure, the force exerted by water on your foundation walls. This reduces the risk of structural damage, preserving the integrity of your home over the long term.
Waterproofing Membrane Services
We at Francis Home Environment will first repair any existing cracks in your foundation by injecting them with a waterproof sealant. Next, we’ll apply high-quality sealants and a waterproof membrane to safeguard your foundation from groundwater and moisture.
Weeping Tile Services
Our technicians will evaluate your current weeping tile to see if it needs to be replaced. In order to successfully redirect groundwater away from your foundation and lower hydrostatic pressure, which can lead to seepage and cracking, we will, if required, install new weeping tile.
Improved Drainage Systems
Poor drainage is often the source of wet soil around your foundation. To keep water away from your foundation, the professionals at Francis Home Environment will regrade the area and improve your external drainage system.
