New and old concrete joint bonding method "Join Bond Method"
Registered in the Ministry of Land, Infrastructure, Transport and Tourism's NETIS "New Technology Information Provision System"! Achieving strong interfacial adhesion with fiber reinforcement!
The Joinbond method involves applying the fiber-reinforced polymer cement adhesive "Joinbond M5000" after high-pressure water treatment. By using this method for additional concrete applications, it significantly enhances the bonding strength at the joint interface, integrates old and new concrete layers, and improves water tightness. It is ideal for applications such as increasing the height or reinforcing existing structures like dams, flood barriers, and waterways, as well as for seismic reinforcement of various public facilities, and for horizontal and vertical joint surfaces in new and old concrete slabs, beams, and columns. 【Features】 ○ Excellent workability, significantly reducing the time required for joint treatment compared to conventional methods (chipping). ○ Spraying or troweling onto the surface of old concrete and pouring new concrete to integrate the old and new concrete layers, enhancing water tightness. ○ After applying to the old concrete surface, it allows for a time frame of 1 day to a maximum of 14 days (at 20°C) before pouring new concrete. ○ Superior adhesion to rebar. ○ NETIS registration number: KK-130043-A For more details, please contact us or download the catalog.
