ABSTRACT:
The invention relates to a method and apparatus for protection against coastal erosion. The protection barrier is formed from a plurality of protection members which are secured together to form a mat of a desired configuration. Each protection member which is formed as a toroidal body, preferably from a discarded tire casing, is at least partially filled with concrete which is deposited about the circumference of the tire casing and occupies not more than one half of the interior chamber formed by the wall of the tire casing. To facilitate preparation of the protection member for use, a conical insert is provided. The tire casing is lowered down over the conical insert, moving towards the wided base of the insert until a lower bead of the casing rim frictionally contacts the wall of the insert. Concrete is then admitted onto the wall of the insert and moves by gravity into the interior chamber, partially filling it. Once the concrete is hardened, the tire casing is lifted, allowing it to be connected with other similarly formed protection members.
