A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

A pier mat of erosion control blocks for abating erosion around piers of a wharf. A mat of blocks is arranged so as to have a linear end edge and a vacant space formed in an opposite end edge thereof, where the vacant space is for surrounding at least a part of a pier. A linear end edge of another similar pier mat is installed so as to abut the end edge of the first mat having the vacant space, thereby fully surrounding the pier. A method of installing a pier mat of erosion control blocks is also disclosed.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

The invention provides a marine infrastructure unit having a polyhedral structure with at least four faces; wherein said unit is formed of concrete and wherein at least one face of said unit comprises at least one tidal pool indentation; for use in building a marine infrastructure and promoting fauna and flora growth in marine environment.

The present invention discloses an ecological seawall water close side embankment slope drainage structure and a construction method thereof. The ecological seawall water close side embankment slope drainage structure includes a seawall, and further includes a wave dissipation ridge and water collecting wells, wherein the wave dissipation ridge is disposed at an upper side of the seawall, a drainage blind ditch is formed in an upper surface of the seawall, and the drainage blind ditch is matched with the wave dissipation ridge; the water collecting wells are distributed at a lower side of the drainage blind ditch at equal intervals, and lower end portions of the water collecting wells communicate with drainage concealed pipes; and pipe seats are disposed at a lower end portion of an inclined plane of the seawall, lower end portions of the drainage concealed pipes are fixedly connected onto the pipe seats, and flap valves are rotationally connected to lower end surfaces of the drainage concealed pipes. The present invention not only can reduce the erosion degree of sea waves to the seawall, but also can collect seawater going over the wave dissipation ridge and discharge the collected seawater into the sea again.
