「This method has been used in actual construction on the Sōrō Bridge on the Seisho Bypass, and approximately 7,000 m² had been completed as of May 2026. The company confirmed not only the removal of salt but also that no defects such as cracking caused by ASR had occurred.」
Actual construction using the LAC desalination method had progressed to approximately 7,000 m², and the company confirmed the salt-removal effect and the absence of defects caused by ASR. - FY2025RestatedAnnual report
「The company is currently carrying out construction using various proprietary maintenance methods, including the improved LAC desalination method, the Repassive method for grout re-injection, and cathodic protection methods, and will continue refining them in preparation for the full-scale expansion of major repair work.」

「The company's proprietary LAC desalination method was trialed on a bridge abutment in a cold mountainous area where large quantities of chloride-based deicing agents are applied, demonstrating its desalination effect. The company has also won an order for major repair work on a PC bridge that has stood in a coastal area for many years and is conducting repeated demonstration tests to further improve the efficiency of the method.」
The LAC desalination method progressed from demonstrating its effectiveness through trial adoption to winning an order for major repair work on a coastal PC bridge. - FY2021First statedAnnual report
「In the previous fiscal year, the company conducted trial construction on an actual bridge and demonstrated a reliable desalination effect.」
For a desalination method that extracts chloride ions from concrete, the company developed a cartridge system using linear anode materials and demonstrated its effectiveness on an actual bridge.
