Concrete blankets, also referred to as Geosynthetic Cementitious Composite Mats (GCCMs), are an innovative class of construction materials used for rapid slope protection, erosion control, and infrastructure lining. They consist of a dry concrete mix encapsulated between layers of geotextiles and fiber meshes that harden upon hydration. Unlike conventional rigid concrete systems, concrete blankets are flexible before setting and conform easily to irregular surfaces. This paper presents a comprehensive technical review of concrete blankets with emphasis on their composition, manufacturing concept, mechanical properties, durability, and field applications. It also discusses installation methodology, testing procedures, and performance evaluation based on experimental and field studies. Results reported in literature indicate compressive strengths of 30–45 MPa, high erosion resistance, and long-term durability under harsh environmental conditions. The study concludes that concrete blankets provide a sustainable, efficient, and cost-effective alternative for slope stabilization, especially in remote and difficult terrains.
