EJN expansion joints are designed to absorb medium movements in infrastructure such as roads, bridges, and structural platforms. These solutions compensate for the expansion and contraction of materials without compromising the integrity of the road surface, ensuring safety, durability, and a professional finish.

Within this family, we find the EJN-80, EJN-100, EJN-140, and EJN-160 models, which cover movement ranges from ±40 mm to ±80 mm. These joints are manufactured with high-quality materials, including metallic elements, elastomers, and reinforced anchoring systems. They feature progressive structural thicknesses, ranging from 47 to 82 mm in height, adapting to different construction needs.

Each model incorporates an optimized technical design to facilitate leveling (Q), pavement transition (P), and installation with M-16 or M-18 metal anchors with a torque of up to 120 Nm. Their configuration is designed to withstand dynamic loads, vibrations, and demanding environmental conditions, making them ideal for medium- to high-level civil engineering projects.

Furthermore, these joints allow for efficient integration with the asphalt, and their structure guarantees a long-lasting seal, minimizing future maintenance. EJN-type solutions comply with European regulations and are widely used in renovations and new construction.
