REJ expansion joints are designed to handle medium movements in infrastructure such as roads, bridge decks, and high-traffic platforms. This family of solutions allows for the controlled absorption of structural displacements without compromising pavement continuity or road safety.

The REJ range includes the REJ-42, REJ-52, REJ-70, and REJ-80 models, with movement capacities between ±22 mm and ±40 mm. These joints are made of high-strength materials and feature a structure that integrates sealing, leveling, and transition systems, optimized for integration with asphalt layers.

Each model specifies precise technical parameters such as the cutting width (N), leveling height (Q), anchor type (M-14, M-16, or M-18), and recommended tightening torque of up to 120 Nm. REJ-type joints are ideal for environments requiring consistent structural performance, low maintenance, and long-lasting durability.

Thanks to their design, these joints allow for efficient installation, perfect adaptation to the road environment, and excellent performance under dynamic loads. Furthermore, they are aligned with European technical standards, making them a reliable solution for new construction or renovation projects.
