A system for strengthening a sloped structure comprises first and second opposing sides, a bottom side, fill material, a plurality of facing baskets adjacent the first side, a plurality of reinforcing members disposed within the fill material, and an impermeable membrane. The second side is adapted to be adjacent the sloped structure. The bottom side adjoins bottom edges of the first and second sides, thereby forming a cavity within the first, second, and bottom sides. The fill material is disposed within the cavity. The impermeable membrane encapsulates at least a portion of the fill material and one or more of the reinforcing members. The facing baskets and the reinforcing members are positioned in a plurality of layers, with each layer comprising one facing basket and one corresponding reinforcing member. The impermeable membrane is positioned to span two or more layers of the plurality of layers. |
