†Enhancing Concrete Trench Drains: The Ultimate Solution Concrete trench drains are essential components in industrial and commercial settings, designed to efficiently remove surface water or contain hazardous materials. These structures play a vital role in maintaining safety and operational efficiency. However, over time, exposure to harsh elements can lead to deterioration, compromising their structural integrity. Common causes of damage include chemical corrosion, physical stress, and environmental factors such as moisture and temperature fluctuations. A recent case involved a battery distribution plant that had suffered from severe concrete degradation. Despite being less than ten years old, the facility had experienced significant damage due to the failure of a protective novolac coating. This allowed corrosive acid baths from the battery manufacturing process to penetrate the concrete. The acid, with a pH between 1 and 2 and a concentration below 98%, caused extensive damage, reducing the concrete’s thickness by nearly half and resulting in approximately 35% of the structure being compromised. Without immediate intervention, the risk of total failure was expected within a year. To address this issue, HJ3 implemented a comprehensive repair strategy. The first step was the removal of all damaged and weakened concrete using abrasive blasting. Following this, the surface was prepared and neutralized to ensure proper adhesion of the repair materials. HJ3 applied its CarbonSeal primer and high modulus paste to restore the original shape and strength of the trench. A carbon fiber reinforcing fabric was then saturated with the same material and installed up to the 2†x 2†shelf, providing additional structural support. To ensure long-term protection, a chemical-resistant top coat was applied across the entire surface, extending 1†beyond the edges. This coating is specifically designed to withstand high concentrations of sulfuric acid, making it ideal for environments where chemical exposure is frequent. The result was a durable, long-lasting repair that restored the trench to full functionality. The cost of replacing concrete trenches can be extremely high, involving not only materials and labor but also significant downtime. In this case, HJ3’s CarbonSeal system provided a more cost-effective solution, allowing the facility to resume operations within just one week. The repair saved the client around 85% compared to a full replacement. With the added chemical resistance, the trenches are now fully equipped to handle ongoing exposure to corrosive substances, ensuring smooth and uninterrupted operations for years to come. If you're dealing with corroded or weakened concrete trenches and need a reliable repair solution, HJ3’s CarbonSeal system offers an effective and long-lasting option.
