Buried-type expansion joint "PA Joint"
No secondary water stop needed - seismic performance achieved! Embedded expansion device developed in Europe.
The "PA Joint" is a buried expansion device that does not require secondary water stopping and possesses seismic resistance due to its ability to expand and contract in all directions, 360 degrees. It exhibits better performance against temperature fluctuations and can accommodate a maximum expansion of up to 100mm. Additionally, the ground cover can be constructed with the same material, allowing for seamless water stopping. 【Features】 ■ Wheel tracking test: 52,500 rotations/mm ■ Durability performance several times greater than the heavy traffic standard value of 3,000 rotations/mm ■ No need for secondary water stopping; also achieves seismic resistance ■ Ground cover can also be constructed with the same material ■ Exhibits the same expansion and contraction performance in all 360 degrees *For more details, please refer to the PDF document or feel free to contact us.
