Exposed wires in prestressed concrete elements are increasingly used across Europe. This method, validated by the CSTB in France, is included in Eurocode 2, EN1992-1-1, though not explicitly mentioned. It avoids silicosis by eliminating silica in factories and is water-friendly, preventing sludge from cuts. The Prensoland patented system add-on for the Tensyland casting machine automates this system for hollow core slabs and beams, requiring no operator. Additionally, our system produces exposed wires without any concrete waste, unlike conventional methods that require removing excess concrete after casting the slab.
