Patent ID: 11162237

Abstract:
A concrete mat apparatus, including a plurality of elongated concrete members, each member being aligned with and next to another concrete member. Each of the concrete members has an upper generally flat surface, a lower generally flat surface, and a plurality of inclined surfaces that each extend away from an upper or lower surface. Reinforcement extends from a first end portion of each concrete member to a second end portion thereof, the reinforcement including a plurality of longitudinally extending reinforcement bars and a plurality of encircling tie bars at spaced apart intervals. Cabling connects each of the elongated concrete members to another of the elongated concrete members. The combination of elongated concrete members has a width and a length that is at least twice as long as the width. The upper inclined surfaces of one of the elongated concrete members forms a plane with the lower inclined surface of an adjacent elongated concrete member. A plurality of loops are provided along opposed edges of the mat, each loop formed by a portion of the cabling. The loops can be spaced between about one and three feet (30.5 and 91.4 cm) apart.
