    This paper introduces a new multicomponent geocomposite, the geosynthetic concrete composite mat (GCCM). Unlike traditional geosynthetic clay layer (GCL) materials that possess a bentonite clay layer as the interlayer, this GCCM has a formulated dry concrete mix impregnated in a three-dimensional geotextile fiber matrix, which hardens upon hydration to a concrete shell. This “dual distinction” multicomponent material is unique. This paper also provides a summary of some of the basic properties of the uncured material (before hydration), followed by an introduction to some important characteristics of the cured material. Mechanical properties are presented for both uncured and cured phases to illustrate the property transformation from the uncured to the cured state and demonstrate the contribution of both the fibrous geotextile phase and the cured concrete phase to the product properties. ASTM Committee D35 GCL test methods were applied as appropriate for this GCCM material, followed by concrete testing of the cured material. Finally, because a number of the applications for this material involve durable protection of soil from erosion under high-flow regimes, hydraulic property test results and some endurance test results are presented. The hydraulic results are from a channel testing arrangement subjecting the installed and cured material to high-velocity water flow.
