How Does Water Infiltration Affect the Structural Integrity of a Building?
As a leading masonry company serving Greater Montréal, Laval, Longueuil, South Shore, and North Shore, Maçonnerie Montréal provides a range of high-quality services, including water infiltration repair services. We understand the potential damage water infiltration can cause to a building's structure and its profound implications for the building's life and safety. This article explores in depth how water infiltration affects the structural integrity of a building, a concern that lies at the heart of our mission to safeguard and maintain masonry structures across Montreal.

The Invisible Intruder: Water and Masonry
Masonry structures, while robust and durable, are not impervious to the elements. One of the most insidious threats to a masonry building is water infiltration, which can lead to a multitude of problems that compromise the structure's integrity.
- Capillary Action and Porosity: Masonry materials like brick, stone, and concrete are porous. They absorb water via capillary action, which can lead to saturation of the material, causing it to expand and contract with temperature changes. Over time, this can weaken the material, causing cracks and fissures that compromise the structure's integrity.
- Erosion of Mortar Joints: Water can gradually erode the mortar joints that bind the masonry units together. As these joints erode, the stability of the entire structure can be compromised.
- Spalling and Efflorescence: Constant exposure to moisture can cause masonry materials to spall or flake off. This process further weakens the structure and can lead to more serious problems if left unchecked. Additionally, water can carry soluble salts to the surface of masonry, creating a white, powdery deposit known as efflorescence. While mostly cosmetic, efflorescence is a clear indicator of a water infiltration issue.

The Stealthy Saboteur: Water and Foundations
Water infiltration doesn't just affect masonry—it can also wreak havoc on a building's foundation, the bedrock upon which the entire structure rests.
- Soil Erosion: Excessive water can wash away the soil supporting the foundation, leading to settlement or even collapse.
- Hydrostatic Pressure: The build-up of water in the soil can create hydrostatic pressure against the foundation, leading to cracks and leaks.
- Foundation Material Erosion: Constant exposure to water can erode the material of the foundation itself, weakening it over time.

The Quiet Quake: Water and Cracks
Cracks in the masonry, either from natural settlement, poor construction, or seismic activity, provide an avenue for water to penetrate the structure.
- Expanding Cracks: Once inside a crack, water can freeze in colder temperatures. Since water expands when it freezes, this can force the crack to widen, exacerbating the damage.
- Compromised Structural Integrity: Cracks can disrupt the load distribution across the masonry structure. When water infiltrates and widens these cracks, it can severely compromise the building's structural integrity.

The Hidden Havoc: Water and Insulation
Water infiltration can also damage a building's insulation, indirectly affecting the structure.
- Reduced Insulation Efficiency: Wet insulation has lower thermal resistance, undermining the building's energy efficiency. This forces heating and cooling systems to work harder, increasing energy costs.
- Structural Wood Damage: If the building incorporates structural wood elements, water-soaked insulation can encourage mold growth and wood rot, further compromising the structure.
