Explore masonry construction techniques that prevent water intrusion, such as flashing.
Water intrusion can be a significant threat to masonry structures, leading to issues such as efflorescence, spalling, mold growth, and structural damage. Proper masonry construction techniques are essential for preventing water from penetrating your building’s brick, stone, or concrete components. By employing the right methods during the construction process, you can ensure your masonry structure remains durable and protected from moisture-related damage. Here are some key techniques DelPrete Masonry and other professionals use to effectively prevent water intrusion in masonry construction.
Proper Flashing Installation
Flashing is one of the most important components in preventing water intrusion in masonry structures. It refers to thin layers of waterproof material that are installed at vulnerable points in the structure, such as around windows, doors, rooflines, and at the base of walls. Flashing directs water away from the masonry and toward designated drainage areas, preventing it from seeping into the building. When installed correctly, flashing acts as a barrier that keeps moisture out, protecting both the masonry and the underlying structure from water damage.
Using Waterproof Mortar
Mortar is the substance that binds bricks, stones, or blocks together in masonry construction. To prevent water intrusion, it’s important to use high-quality mortar that is designed to resist moisture. Waterproof or water-resistant mortar mixes help create a tight seal between masonry units, reducing the chances of water penetrating the joints. This ensures that water stays on the surface, where it can evaporate naturally, rather than seeping into the structure and causing damage. Regular maintenance of mortar joints, such as tuckpointing, is also essential to keep them in good condition and prevent water ingress over time.
Incorporating Weep Holes and Drainage Systems
Weep holes are small openings placed at the base of masonry walls to allow any moisture that enters the structure to escape. These holes help manage water that may accumulate behind the masonry due to condensation, rain, or other sources of moisture. Without weep holes, trapped water can lead to long-term damage, including mold growth and weakening of the wall’s structure. Combined with internal drainage systems, weep holes allow water to safely exit the masonry, preventing it from causing deterioration. A well-designed drainage system behind the masonry ensures that water doesn’t accumulate, keeping your structure dry and protected.
Applying a Sealant or Waterproof Coating
One of the most effective ways to prevent water intrusion is by applying a waterproof sealant or coating to the exterior surface of the masonry. These sealants act as a protective barrier, preventing water from penetrating the porous materials of brick or stone. A professional mason can recommend the right type of sealant for your specific masonry materials, ensuring it provides long-lasting protection without compromising the structure’s breathability. Waterproof coatings are particularly useful in areas prone to heavy rainfall or where the masonry is frequently exposed to water.
Ensuring Sufficient Overhangs and Water-Shedding Features
Architectural design plays a key role in protecting masonry from water intrusion. Roof overhangs, for example, help to direct rainwater away from the walls, reducing the amount of moisture that comes into direct contact with the masonry. Similarly, features such as drip edges, cornices, and copings can help shed water away from the building. By incorporating these water-shedding features during the masonry construction process, you can limit the exposure of masonry surfaces to rainwater, reducing the risk of water intrusion and long-term damage.
