Exterior Basement Waterproofing
Water infiltration in the basement can lead to serious damage—and expensive repairs. Over time, it can weaken your foundation and compromise the structural integrity of your home. While interior waterproofing helps, exterior basement waterproofing adds an extra layer of protection by redirecting water before it has a chance to seep in.

We’re available 24/7 to assess your property and provide cost-effective, durable solutions to waterproof exterior basement walls for lasting peace of mind.
Our Exterior Basement Waterproofing Process
To properly waterproof exterior basement walls, we begin by excavating the soil around your home’s foundation. Though it may appear extensive, this step is essential for complete access and thorough results. Here’s how the process works:
1
Excavation and inspection of your foundation to check for damage
2
Application of exterior waterproofing membrane
3
Installation of weeping tile to carry water away from your foundation
4
Upgrading drainage systems to prevent water accumulation
5
Final inspection and soil backfilling for a clean finish
Why Exterior Basement Waterproofing is Important
By blocking water before it reaches the foundation, exterior waterproofing offers protection where it matters most. Interior methods only address water after it’s already inside, reducing moisture but not eliminating exterior pressure or leaks. Melting snow, heavy rain, or saturated soil can still put stress on your foundation walls.
Exterior basement waterproofing forms a watertight seal and helps prevent hydrostatic pressure from building up around your home. That reduces the risk of water intrusion, structural cracks, and costly repairs down the line.
Waterproof Membrane Application
Anchor Home Comfort’s waterproofing technicians seal any visible cracks with high-performance materials, then apply a protective waterproof membrane. This barrier shields your foundation from water and moisture buildup in surrounding soil.
Weeping Tile Repair and Installation
If your current weeping tile system is damaged or outdated, we’ll replace it with new piping designed to move water away from the home efficiently—reducing the risk of leaks and foundation movement.
Drainage Improvements
Poor grading or clogged drains can cause water to collect at your home’s base. Our team corrects these issues by improving grading and enhancing surface drainage, keeping water away from your foundation after every rainfall.
Protect your basement now and avoid costly foundation repairs later. Trust Anchor Home Comfort for waterproof exterior basement walls that last.

FAQs About Exterior Basement Waterproofing
What Are the Signs That My Home Needs Exterior Basement Waterproofing?
If your basement needs waterproofing, you might notice these signs:
- Damp or humid basement walls, along with musty smells
- Water stains or chalky white residue (efflorescence) on concrete surfaces
- Mould, mildew, or dark patches forming on basement walls
- Cracks developing along the basement floor or foundation walls
- Water collecting around the base of your home—especially when nearby properties remain dry
What Is the Difference Between Interior and Exterior Basement Waterproofing?
Interior and exterior basement waterproofing both aim to prevent water damage, but they work in different ways.
- Interior waterproofing focuses on managing water once it enters the basement—by collecting and redirecting it safely through sump pumps or drainage channels.
- Exterior basement waterproofing, on the other hand, blocks water before it ever reaches the foundation. It also reduces pressure buildup from surrounding soil.
- Exterior systems last longer overall, but they require excavation, which can be more intrusive during installation.
How Long Does Exterior Waterproofing Last?
When done professionally using high-grade materials, exterior basement waterproofing typically provides more than 25 years of protection. Many Ottawa homeowners enjoy long-term peace of mind, with little to no maintenance required, once the system is in place.
