Water Infiltration: Testing, Repairs, and Prevention

By | Waterproofing

Water is so essential for life but can also be one of the greatest threats to the integrity of our built environments. Its pervasive nature allows it to seep into the smallest cracks and imperfections. When water infiltration occurs, it can exert tremendous pressure, especially when the water freezes or when it leads to soil movement beneath foundations. Testing, repairing, and preventing water intrusion is critical to your building’s longevity. It’s one of those problems that will only get worse over time. This article aims to help you understand water infiltration and how to address it. What Happens When Water Infiltrates the Building Envelope? Water flows without feeling or malice as it respectfully follows the laws of gravity. Your building envelope acts against water to divert it elsewhere and prevent water infiltration. When the envelope or its components fail, and water infiltrates the building envelope, several things can happen, none of which are good for your building. Water molecules are sticky, which means they can carry dirt, pollutants, and other contaminants into your building, exacerbating the damage. Water dissolves other molecules, further breaking down building materials and facilitating mold growth. Water expands and contracts, causing cracks and further damage as temperatures fluctuate. Common entry points for water infiltration are roofs and ceilings, anywhere there are cracks, such as the facade, foundation, or basement, and where sealant fails around entry points or windows. Water isn’t taking a nap behind the scenes. It’s tirelessly breaking down building components, making more room for…
