One proven way to create strong construction joints is to use re‑bend reinforcement systems. Peikko’s ARBOX® Plus improves on traditional re‑bend systems by providing higher load capacity and European Technical Approval (ETA) that guarantees safe use in many applications.
ARBOX® Plus works by storing bent rebars inside a special steel box that is attached to the formwork of the first concrete part. After the first concrete section or precast element is poured and hardened, the cover is removed, the rebars are rebent into position, and the next concrete section is cast. In the case of precast elements, the rebars are overlapped, and the connection is filled with mortar.
This creates continuous reinforcement between the two concrete parts, helping them function as a single solid structure.
What makes ARBOX® Plus stand out is its unique steel box surface. Its rough, embossed surface helps increase the friction between the surfaces of connected elements, therefore increasing the joint’s shear capacity. ARBOX® Plus, with a special steel box surface, was tested according to strict European standards (EAD 160031-00-0301) and has received an official European Technical Assessment (ETA_23-0895). This confirms that it can carry very high loads both along and across the joint, with high continuous quality control provided by Peikko under CE marking.
Overall, ARBOX® Plus offers a reliable, tested, and simple way to connect concrete sections. It supports safer construction and faster building processes, making it a strong choice for both cast‑in‑situ and precast projects.
