"Concrete slab sinking correction method" contributes to the longevity of social infrastructure.

Using high-strength urethane resin, we will correct the deformations such as subsidence, steps, flapping, gaps, and cavities that have occurred in the concrete slab, without excavation and within a short construction period.

The Upcon concrete slab settlement correction method (KT-080008-A, NETIS registration period ended in October 2014) quickly resolves issues such as settlement, unevenness, flapping, gaps, and voids that occur in concrete pavement slabs commonly used in highways and other areas, using specially developed high-strength polyurethane resin. It achieves a short construction period by utilizing a highly mobile plant without breaking the existing pavement slabs or requiring excavation work. This minimizes the period of service suspension and has a proven track record as a planned and efficient method for maintaining social infrastructure. This technology is also adopted not only for highways but also for repair work in ports and airport aprons, as well as disaster recovery work. Upcon will exhibit at the "Highway Techno Fair 2023," where cutting-edge technologies supporting highways will be showcased. Date: November 9 (Thursday) and 10 (Friday), 2023, from 10:00 to 17:00 Location: Tokyo Big Sight, West Hall 3 Exhibition Booth No: A-04 On that day, there will also be a demonstration of settlement correction using polyurethane resin. We invite you to take this opportunity to see it. We look forward to your visit.
