top waterproofing techniques by masonry contractors

​Masonry techniques can be used to help waterproof a home by preventing water from penetrating the building envelope.  This is especially important in a city like Cambridge where we see 1.26 inches of precipitation and has 44.01 rainy days annually.

Here are some commonly used techniques:

Use of water-resistant materials:

Using water-resistant materials like bricks, stones, and concrete blocks can help to prevent water from seeping through the walls. These materials have low porosity and can withstand water penetration to a certain extent.

Proper jointing:

Proper jointing between the bricks or stones can help to prevent water from entering the walls. Mortar joints should be well compacted and free from voids, cracks, and gaps.

Application of waterproof coatings:

Waterproof coatings can be applied to the exterior masonry walls to protect them from water penetration. These coatings can be made from various materials, such as silicone, acrylic, or polyurethane, and they form a barrier against water.

Use of flashing:

Flashing is a material used to prevent water from seeping into the gaps between the masonry and other materials, such as doors and windows. It is commonly made of metal, such as aluminum or copper, and is installed at the base of the wall and around the openings.

Slope the ground away from the home:

The slope of the ground around the home can be adjusted to prevent water from accumulating around the foundation walls. This can be achieved by grading the soil around the foundation so that water flows away from the house.

Proper drainage:

Proper drainage is essential for keeping the home dry. This can be achieved by installing gutters and downspouts to carry water away from your property.


Case Study

​Earlier this spring, a homeowner in the Preston area of Cambridge, Ontario, contacted Masonry Cambridge after noticing water seepage and musty smells in their basement following heavy rainfall. After a thorough inspection, we identified aging brick mortar and poor grading as the culprits behind the issue. Using advanced masonry waterproofing techniques, including repointing degraded mortar joints, applying a high-performance waterproof sealant, and installing a proper drainage channel along the foundation, our team resolved the problem before further structural damage could occur. According to the City of Cambridge’s Flood Risk Mapping, older neighbourhoods near the Grand River, like Preston and Galt, are especially vulnerable to seasonal water infiltration — making preventive masonry solutions critical.

The results were immediate: not only did the homeowner report a completely dry basement during April’s record 45 mm rainfall, but they also noticed a reduction in humidity and air quality issues. Our expert waterproofing work helped them avoid costly interior water damage and preserved the long-term value of their home. According to a 2023 report from the Region of Waterloo, homes that undergo professional waterproofing and masonry repairs can see property value increases between 3% and 8%, especially in flood-prone areas. At Masonry Cambridge, we’re proud to protect local homes with proven, durable solutions that stand up to Ontario’s unpredictable weather.
