What Causes Water Infiltration in Masonry Structures?

The architectural charm and durability of masonry structures often come with unique challenges that require comprehensive understanding and preventive measures. One of these challenges, common yet demanding immediate attention, is water infiltration. As a leading masonry company in Montreal, at Maçonnerie Montréal, we take water infiltration seriously. This article aims to elucidate what causes water infiltration in masonry structures, highlighting the importance of proactive maintenance and expert repair services.

Firstly, let's understand what masonry is. Masonry involves building structures from individual units, typically from materials such as brick, stone, concrete block, glass block, or tile, bound together by mortar. While masonry is praised for its strength and aesthetic value, like any other construction material, it is not immune to the effects of weather and time. Water infiltration is one such adverse effect that can lead to significant damage if not addressed promptly.

Capillary Action and Porosity

One of the primary causes of water infiltration in masonry structures is capillary action. Masonry materials are naturally porous, meaning they have tiny holes or pores that allow liquids and gases to pass through. Water can seep into these pores, and due to capillary action, rise against gravity. This process is often referred to as rising damp, which can cause substantial structural and cosmetic damage over time. It can lead to the decay of mortar joints, the breakdown of the masonry unit, efflorescence, and unsightly damp patches on walls.

Construction Flaws and Material Degradation

Sometimes, the cause of water infiltration is due to flaws in the construction process. For example, improper installation or the use of low-quality mortar can create a conducive environment for water infiltration. Over time, these weaker points in the masonry structure might allow water to seep in, leading to progressive water damage.

Material degradation is another common cause. Masonry structures are not immune to the harsh effects of nature. Elements like wind, rain, freeze-thaw cycles, and even sunlight can degrade masonry over time. As the materials age and degrade, they become more susceptible to water infiltration.

Improper Sealing

Another critical factor causing water infiltration is improper sealing around windows, doors, and roof intersections. These areas, if not sealed correctly, provide an easy path for water to seep into the structure. Over time, this not only causes visible damage like paint discoloration and mould growth but can also lead to serious structural problems if not addressed in time.

Cracks and Structural Damage

Cracks in masonry, either from natural settlement, inadequate foundation support, or seismic activity, can also lead to water infiltration. These cracks provide a direct path for water to penetrate the masonry, leading to potential moisture-related problems inside the structure.
