Buried type expansion joint "PA Joint"

No secondary water stop needed; seismic performance has also been achieved! An embedded expansion device boasting high durability.

The "PA Joint" is a buried type expansion device that does not experience flow or cracking specific to joints, and is durable with high durability. It exhibits better performance against temperature fluctuations and can accommodate a maximum expansion of up to 100mm. Its expansion capability in all 360 degrees also provides seismic resistance, eliminating the need for secondary water stopping. Additionally, it significantly improves the durability issues associated with conventional buried joints, suppressing the occurrence of subsidence and cracking due to flow, ensuring the safety of passing vehicles. 【Features】 ■ Durability: Expansion performance is significantly superior compared to conventional special composite devices. ■ Quietness: The main body can be smoothly finished at room temperature for a flat installation. ■ Water stopping ability: Excellent water stopping capability as the ground cover can be made from the same material. ■ Seismic resistance: Maintains a maximum expansion of 100mm in all 360 degrees. ■ Versatility: Can be installed in locations where buried types were previously not selectable. *For more details, please download the PDF or feel free to contact us.
