It is a flexible fabric impregnated with a specially formulated cementitious mixture that hardens on hydration to form a thin, durable layer of waterproof and fireproof concrete.
The concrete blanket is made up of a three-dimensional matrix of fibers and a PVC sheet on the bottom surface, ensuring that the material is waterproof. The blanket can be hydrated either by spraying the surface with water or by submerging it in water.
