Concrete Repair - National Precast Concrete Association

Jan 08, 2018  The best repair product is one with mechanical properties that closely match the original concrete. Therefore, if the precast product has compressive strength required to exceed 4,000 psi and the actual testing shows strength of 5,000-to-6,000 psi, the repair material needs to exceed 4,000 psi to ensure compliance.
