Creating an expansion joint section integrated with the road! Providing driving performance that completely eliminates the perception of bridge joints.
The "Inner Joint" is a bridge expansion device that evenly distributes and absorbs the expansion and contraction of girders, thanks to the properties of a special composite material and the expansion mesh laid in between. Due to the behavior equivalent to that of asphalt, it does not create any bumps, resulting in excellent drivability without generating noise or vibration. Additionally, the special composite material has excellent adhesion to asphalt pavement, and waterproof treatment is applied with elastic sealing material in the joint gap, preventing any leakage. 【Features】 ■ Structure that evenly distributes and absorbs the expansion and contraction of girders ■ Excellent drivability with no noise or vibration ■ Waterproof treatment prevents leakage *For more details, please refer to the PDF document or feel free to contact us.
