In combination with the PENTAFLEX® module, two single-row FERBOX® rebend connections become a waterproof reinforcement connection. FERBOX® rebend connectors connect two reinforced concrete parts together statically or structurally. To seal the resulting construction joint and so prevent the passage of water through the joint, another reinforcement box with PENTAFLEX® joint sheet is additionally installed between two single-row FERBOX® reinforcement boxes – the PENTAFLEX® module. This guarantees the watertightness of construction joints with rebend connections using proven PENTAFLEX® technology.
