The Epicore MSR Composite Floor System must be securely shored prior to pouring concrete. The primary shoring underneath the deck being poured should be spaced at a maximum of 5’ on center (consult Infinity for actual shoring requirements). The primary shoring should remain in place until the concrete reaches 75% compressive strength or at least 72 hours. After relieving the primary shoring, the system must be reshored for two floors below the primary pour.
