[NETIS Registration] Integrated Method for Expansion Devices and Deck Waterproofing (AOS Method)
NETIS Registration Number: CB-170021-A / Patent No. 6095842 / Integrated Method for Expansion Devices and Waterproofing of Slabs - AOS Method -
Improving economic efficiency in small bridges under 20 meters.
The "Integrated Method of Expansion Device and Deck Waterproofing (ARCHIST ONEPIECE-GEL SYSTEM®)" achieves a reduction in construction time and high economic efficiency 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: ONEPIECE-GEL JOINT and ONEPIECE-GEL PROOF must be used simultaneously.* 【Features】 ■ More than 15% reduction in construction costs compared to conventional methods ■ Easy to construct at room temperature, allowing for shortened construction time ■ Passes performance verification tests for 15 years *For more details, please contact us or download the PDF to view.*
