CSS-CM Cementitious Matrix

CSS-CM is a one-component, shrinkage-compensated, polypropylene-fiber reinforced cementitious matrix designed to be field installed with CSS-UCG, CSS-BCG and CSS-HBCG carbon grids to create a fabric-reinforced cementitious matrix (FRCM) composite for structural reinforcement applications. Used without carbon grids, CSS-CM functions as a high performance, sprayable repair mortar. This product has been evaluated per ICC-ES AC434 for concrete and unreinforced masonry strengthening using fabric-reinforced cementitious matrix (FRCM) and steel reinforced grout (SRG) composite systems. This product is part of the tested assembly in UL Design No. N859, which achieved a four-hour fire rating when subjected to ASTM E119 / UL 263 full-scale fire testing. Please refer to UL Online Certifications Directory for the UL listing.
