Why Exterior Waterproofing Is the Most Effective Solution

Exterior waterproofing stops water at the source before it enters your home. Unlike interior drainage systems that manage water after it enters the basement, exterior systems prevent water infiltration entirely.

Benefits of Exterior Waterproofing

• Prevents basement leaks and flooding
• Reduces hydrostatic pressure against foundation walls
• Protects structural integrity
• Prevents mold and mildew growth
• Increases long-term property value

By sealing the foundation from the outside and improving drainage around your home, exterior waterproofing provides a long-lasting and reliable solution.

Our Exterior Waterproofing Process

At Michael Durham Landscaping, we follow a proven waterproofing process designed to permanently protect your foundation.

1. Foundation Inspection

We inspect your foundation walls, grading, and drainage systems to determine where water is entering your home.

2. Excavation

The soil around the affected foundation wall is carefully excavated to expose the exterior surface.

3. Crack Repair & Surface Preparation

Any visible foundation cracks are sealed and the surface is prepared for waterproofing membrane installation.

4. Waterproof Membrane Installation

A durable waterproof membrane is applied to the foundation wall to prevent water infiltration.

5. Drainage Installation

We install proper drainage systems to redirect water away from the home.

6. Backfill & Yard Restoration

After the waterproofing work is completed, the excavation area is restored and properly graded to improve water runoff.

Exterior Foundation Waterproofing for Homes

Waterproofing your foundation isn’t about slapping on sealant and hoping for the best; it’s about preventing real damage. We start by exposing the foundation wall, checking for cracks, and repairing any issues before installing a proper waterproofing system.

Our approach is built for Ontario’s harsh weather. We use proven methods like drain installation, waterproof membranes, and solid backfilling to keep water out for good. If it’s a basement leak, pooling water, or a wet foundation, we stop it at the source, so you get a dry basement that stays that way.

Yard Grading and Drainage Solutions

If water pools near your foundation after a storm, the issue may not start with your basement; it starts with your yard. Poor grading allows runoff to flow toward the structure, putting unnecessary pressure on the foundation and increasing the risk of a leaky basement or foundation crack.

Our team provides site-specific grading corrections and installs drainage systems, including French drains for yard runoff. These systems are designed to keep surface water away from the home, reducing the likelihood of a basement flood or costly basement repair.

As experienced landscape grading and drainage contractors, we ensure your property is sloped correctly and integrated with a reliable waterproofing solution. No shortcuts, just effective water control that supports your overall basement waterproofing system.

Signs You May Need Waterproofing or Grading

How do you know it’s time to call us? Look for these red flags:

• Water stains on the basement walls
• Musty odours (yep, that’s usually water)
• Cracks in your foundation
• Water pooling around your foundation after storms
• Soil erosion near your walls

These issues often point to drainage failure, grading problems, or the need for interior waterproofing or external waterproofing. If left untreated, they can lead to costly damage or a full basement waterproofing project.
