  • Method of constructing a seawall reinforcement or jetty structure
    Patent number: 5087150
    Abstract: A weighed water permeable fabric is laid over a bottom sediment and an adjacent seawall structure. A layer of integral paired star-shaped blocks is laid over the bottom covering fabric in an interrelated pattern in a horizontal and vertical plane. A bore is located within each star-shaped portion of the block and these bores are aligned with corresponding bores in blocks mounted vertically. A concrete piling is drilled or poured in place through the bores to the bottom sediment to hold the structure in place against severe storm surges and resist outward movement of the seawall.
