Hyosung Heavy Industries Develops Concrete Durability Tech to Extend Building Lifespan

Hyosung Heavy Industries has developed a ‘concrete durability enhancement technology’ to inhibit corrosion of reinforcing bar/steel within concrete.

This technology is a dual-composite technology that enhances the alkalinity of the concrete matrix for higher carbonation resistance and blocks moisture and carbon dioxide penetration through the effect of external paint. Concrete carbonation is a phenomenon in which air-derived carbon dioxide penetrates into concrete and causes rebar corrosion.

In particular, it can effectively supplement micro-cracks in exterior walls with an elongation rate 10-fold higher than that of existing water-based paints, and its salt resistance capability in high-saline environments such as the seashore is deemed to be two-three-fold better than that of general water-based products, making a big difference in extending the building lifespan.

Since 2023, Hyosung Heavy Industries has been developing concrete internal reinforcement technology through joint industry-academia-institute research with Cheongju University and DONGNAM Co. Ltd.. Moreover, it has completed ‘concrete durability improvement technology’ by jointly developing concrete external paint technology with global paint manufacturer KCC Corporation. In June, it acquired technology certification from the Korea Concrete Institute, the most preeminent concrete academic society in Korea.

Hyosung Heavy Industries plans to expand the technology’s application to major construction projects, starting with ‘Harrington Square River Park’ in Gyeongan, Gwangju. Taking its cue from the actual application results at each site, it plans to adopt a dedicated quality management process and promote construction with even higher levels of perfection.

A Hyosung Heavy Industries official said, “The technology we have developed this time is convergence technology that ensures the long-term lifespan of buildings,” and added, “It will serve as the basis for enhancing the quality credibility of our premium residential construction brand, including Harrington Place.”

Meanwhile, Hyosung Heavy Industries supplies various residential products such as apartments, mixed-use housing, and high-end villas nationwide under the brands of ‘Harrington Place,’ ‘Harrington Square,’ and ‘Harrington Court.’ In particular, it has actively introduced eco-friendly materials and smart home systems to create a comfortable and safe residential environment, and has been recognized for its top-tier credibility and brand value by earning the Consumer Target Brand Award for seven consecutive years. In particular, its ‘Harrington Place’ brand won the grand prize in the apartment category at the ‘2025 Customer Brand Affinity Awards’ for its fourth consecutive year.
