Re-new System Co., Ltd.

Korea's economic growth, which was begun in earnest from the 1990s, remarkably prospered the construction industry. Subsequently, the large-scaled constructions, such as Gyeongbu (Seoul-Busan) High-Speed Railway, Incheon International Airport, Seohaean Expressway (connects Incheon and Mokpo along the western coastline), subway constructions by each local autonomous entity, World Cup stadiums (completed in 2002), etc., have been propelled under a governmental policy. The prosperity of construction bore stately and aesthetic structures. However, the structures are causing many troubles including crack, leakage, etc., let alone maintaining status quo. In particular, the leakage problem of completed concrete structure has been treated as an incurable headache among the related. To solve the leakage problem, RENEW SYSTEM developed TURBO-SEAL and POLY-AS (water-proofing material), using new material that automatically treats damaged parts, through industry-university cooperation with Seoul National University of Technology. In addition, it was designated as the 376th New Technology by Ministry of Construction and Transportation. The above-mentioned material is a new-typed waterproofing and repairing material indicating high adhesive and swelling efficiency. Actually, the present water-proofing material just functions as a vulcanizing adhesive. On the other hand, the new material restores a damaged part and automatically treats the part, for it adopted liquidity to actively adapt the external environment and the behavior of concrete, based on new mechanism.
