6 ways masonry contractors can keep water at bay

Masonry, with its enduring beauty and structural integrity, has been a construction staple for centuries. However, like all building materials, it's not impervious to water damage. That's where the expertise of masonry contractors in Oakville comes into play. These professionals understand the importance of waterproofing in masonry projects and employ specialized techniques and materials to protect your investment. In this blog post, we'll explore how stone and brick masons can help safeguard your masonry work against water intrusion.

How a Masonry Company can Implement Waterproofing

1. Surface Sealants

Surface sealants are applied directly to the exterior of the masonry. They create a protective barrier that repels water, preventing it from penetrating the surface. These sealants can be clear or tinted and are available in different formulations, including silicones and siloxanes.

2. Water-Repellent Coatings

Water-repellent coatings are designed to minimize water absorption into the masonry while allowing it to breathe. These coatings are an excellent choice for brickwork and stone masonry. They help maintain the natural appearance of the materials while providing essential protection.

3. Masonry Waterproofing Paints

Masonry waterproofing paints are thicker and more durable than standard paints. They are specifically formulated to resist water penetration, making them suitable for both interior and exterior masonry surfaces.

4. Silicone Sealers

Silicone sealers are highly effective in preventing water infiltration. They create a hydrophobic surface that repels water, keeping it from seeping into the masonry. Silicone sealers are often used in high-moisture areas, such as bathrooms and kitchens.

5. Interior Waterproofing Systems

For below-grade masonry, such as basements, masonry contractors may recommend interior waterproofing systems. These systems include interior drainage solutions like sump pumps, vapor barriers, and sealants applied to the interior surfaces to redirect moisture away from the foundation.

6. Caulking and Joint Sealing

Caulking and joint sealing are essential for sealing gaps, cracks, and joints in masonry surfaces. Masonry experts carefully inspect these areas and apply sealants as needed to prevent water infiltration.

The Benefits of Professional Waterproofing

Enlisting the services of masonry contractors for waterproofing in your masonry projects offers several advantages:

- Expertise: Masonry professionals have the knowledge and experience to assess your project's specific waterproofing needs accurately.

- Customization: They can tailor waterproofing solutions to your masonry materials, ensuring optimal protection without compromising aesthetics.

- Durability: Professionally applied waterproofing is durable and long-lasting, providing peace of mind for years to come.

- Cost-Efficiency: Preventing water damage through waterproofing is often more cost-effective than repairing extensive damage later.


Case Study

At Masonry Oakville, we recently implemented advanced waterproofing materials and techniques for a homeowner in the Bronte neighbourhood, an area prone to heavy rainfall and spring thaw. Oakville averages about 843 mm of rain annually, with a wetter season from late March through November—including over 8 wet days per month in summer. To protect the property's new stonework, we installed a comprehensive exterior waterproofing system: applying polymer-coated membranes directly to foundation walls, integrating a parging layer with cement-lime mortar, and installing a high-capacity weeping-tile drainage system. This setup redirects hydrostatic pressure away from the structure and prevents water infiltration effectively.

By addressing Oakville’s notorious clay soils and flood-prone conditions—highlighted by recent reports of widespread basement seepage and 1-in-100-year flash floods in Halton —we ensured the masonry remains both beautiful and resilient. The homeowner immediately noticed a dry basement and reduced humidity levels, eliminating mold concerns and avoiding costly future damage. Supported by local municipal subsidy programs for flood prevention, this waterproofing investment both protected the home and added long-term value—making it a smart, proactive choice in a climate where water is the biggest threat to masonry durability.


Waterproofing is a crucial aspect of masonry construction and maintenance. Oakville masonry contractors are your allies in preserving the beauty, functionality, and longevity of your masonry work.
