PURPOSE: A geocomposite comprising a polypropylene nonwoven fabric layer as external two layers and a polyethylene grid or sheet layer as an intermediate layer in which an antioxidant, an ultraviolet rays stabilizing agent, a flame retardant, a flame additive, a moth proofing agent and rat-proofing agent are added on each layer is provided, which has excellent weather resistance, flame resistance, moth proofing property and rat-proofing property. CONSTITUTION: The geocomposite comprises a polypropylene nonwoven fabric layer comprising highly crystalline polypropylene resin having a melt index of 10 to 40, a crystallinity of 70 to 80%, a melted portion of 0.1 to 1.0% as external two layers and a polyethylene grid or sheet layer comprising polyethylene resin having a melt index of 0.01 to 1.0, a density of 0.945 to 0.960g/cm3 and minimum required strength of 10 to 40 as an intermediate layer, wherein an antioxidant, an ultraviolet rays stabilizing agent, a flame retardant, a flame additive, a moth proofing agent and rat-proofing agent are added on each layer.
