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.

Residential Waterproofing Services

Basement water issues often go unnoticed until cracks form or musty odours appear, but by then, the damage has already started. Acting early is the most effective way to avoid costly repairs and long-term structural problems.

Our residential waterproofing services are designed to prevent leaks and moisture intrusion before they escalate. We provide complete interior and exterior waterproofing, install French drains, and address drainage issues with proven methods. Every system is tailored to your property’s needs and built to withstand Ontario’s climate. With transparent pricing and no hidden costs, we deliver long-term solutions that keep your basement dry and your foundation protected.

Commercial Waterproofing Services

Water damage can interrupt business operations, lead to costly repairs, and create safety risks. That’s why commercial properties require a waterproofing contractor with experience, precision, and a clear plan.

We offer complete foundation waterproofing services, including targeted drainage and structural protection. For properties requiring exterior water control, we also provide French drain installation and grading corrections to move surface water away from key areas.

As a licensed waterproofing specialist, we understand the demands of commercial schedules. Our crews work efficiently and safely, with minimal disruption to tenants, customers, or staff. When needed, our team also supports site drainage through landscape grading services that ensure proper slope and runoff management.

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.

Our Waterproofing Process

Waterproofing isn't about surface fixes; it’s about stopping the problem at its source. Our process is designed to address your waterproofing needs with the right methods and materials from the start.

We begin with a detailed site assessment to identify where water is entering. From there, we excavate the foundation to inspect for damage, then complete any necessary basement leak repairs. Once the foundation is sound, we install a full exterior basement waterproofing system, including membrane application, basement wall sealing, and reliable drainage.

Each project is completed using proven waterproofing methods and high-grade waterproofing materials. Whether it's part of a full basement waterproofing service or integrated with landscape grading and drainage, the goal is the same: a dry, protected foundation that stays that way.
