Concrete: The Essential Yet Vulnerable Building Material

Concrete is a fundamental material used globally in various parts of residential construction including covered porches, patios, driveways, and foundations. Although it’s known for its durability, concrete is not entirely resistant to environmental and human factors. Over time, it can be compromised by temperature fluctuations, moisture, and chemical exposure, despite its robust nature.

Concrete, often overlooked for its porosity, typically takes about 28-30 days to fully cure after pouring. Following this process, it remains prone to stains from various sources, such as oil leaks from vehicles or berry stains from trees. Even prolonged contact with tree leaves can result in unsightly marks on the concrete surface.

Recently, one significant threat to concrete’s integrity has been the use of brine for de-icing. For instance, during an early winter snowstorm in Nashville, the Tennessee Department of Transportation and local municipalities applied brine on heavily trafficked roads. Brine, which contains chemicals like calcium chloride and magnesium chloride, prevents ice from bonding with the pavement and enhances road safety. However, these chemicals also increase moisture saturation in concrete, leading to potential damage.

To protect and maintain the appearance of concrete, sealants can be very effective. Products like Siloxane Sealer and Surfkoat Repel 309 come highly recommended. It’s important to apply sealant before heavy usage and to reapply every 12-15 months. While sealants can extend the life of concrete, they are not foolproof. For vehicles that have driven on roads treated with brine, regularly washing the tires and undercarriage can prevent these harsh chemicals from penetrating the concrete and causing further degradation.

By taking these proactive steps, you can help preserve both the structural integrity and aesthetic appeal of your concrete surfaces
