Belzona Facts
The compressive strength of Belzona 4131, fully cured has been tested to a compressive strength of 13,000psi. (89.6 MegaPascals (MPa)) The compressive strength of cured concrete can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi (70 MPa) are specified for certain applications. These are rated on a 150mm concrete block which has been left to fully cure for 28 days. Therefore, the Belzona 4131 is anywhere between 3 and 6 times stronger than industrial concrete at the recommended 6mm thickness.
