Integrated construction method for expansion devices and waterproofing of floor slabs - AOS method (NETIS)
NETIS Registration Number: CB-170021-A / Patent No. 6095842 / Integrated Method for Expansion Devices and Waterproofing of Slabs - AOS Method -
[NETIS Registration Method] No need for processes such as anchor installation or rebar welding! A method that integrates expansion devices and floor waterproofing, reducing construction and curing time by 50%.
The "Integrated Method of Expansion Devices 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, allowing 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. *For bridge surface waterproofing materials, both room temperature membrane-type waterproofing materials (ONEPIECE-GEL PROOF) and membrane-type deck waterproofing (asphalt heating type) can be used. 【Features】 ■ More than 15% reduction in construction costs compared to conventional methods ■ Easy to construct at room temperature, enabling a reduction in construction time ■ Passes performance verification tests for 15 years *For more details, please contact us or download the PDF to view.
