NEXCO Structural Construction Management Guidelines: Obtaining Proof of Spalling Prevention Performance! Introducing an excellent construction method that also leads to shortened construction periods.
The "Hybrid Sheet Method" is a construction technique that involves adhering a weather-resistant "HB Sheet (Hybrid Sheet)" to the surface of concrete using adhesive. Similar to concrete protective coatings, it possesses the ability to suppress salt damage and carbonation, providing measures against deterioration (salt damage and carbonation). Since it can be reinforced by simply overlapping without removal, the initial construction will not be wasted when reinforcing with steel plates or CFRP in the future. Additionally, compared to conventional methods, the number of traffic regulation days is reduced by about half, leading to a shortened construction period. 【Features】 ■ Excellent peeling prevention performance ■ Contributes to shortening the construction period ■ Measures against deterioration (salt damage and carbonation) are also possible ■ Can be reinforced by overlapping without removal ■ Obtained certification for peeling prevention performance according to NEXCO structure construction management guidelines *For more details, please refer to the PDF document or feel free to contact us.
