We support repair design work "AOS method (NETIS registered)"
NETIS Registration Number: CB-170021-A / Patent No. 6095842 / Integrated Method for Expansion Devices and Waterproofing of Slabs - AOS Method -
Improvement of cost-effectiveness in small bridges under 20 meters.
The "Integrated Method of Expansion Devices and Deck Waterproofing (ARCHIST ONEPIECE-GEL SYSTEM®)" achieves a reduction in construction time and high cost-effectiveness by using the same asphalt emulsion-based expansion material and waterproofing material for the installation of embedded expansion devices and membrane-type deck waterproofing. This method maintains both the expansion device function and waterproofing function in bridges. *Note: It is necessary to use ONEPIECE-GEL JOINT and ONEPIECE-GEL PROOF simultaneously. 【Features】 ■ More than 15% reduction in construction costs compared to conventional methods ■ Easy to construct at normal temperatures, allowing for shortened construction periods ■ Passes performance verification tests for 15 years *For more details, please contact us or download the PDF for further information.
