Revetment unit and method for protecting shoreline or waterway

A method for providing a protective covering against erosion of a shoreline or waterway embankment comprising the steps of:

• a) providing a number of identical units, each of which comprises a generally L-shaped web having top and bottom surfaces and first and second arm members converging at an apex and forming a 90.degree. right angle, said arm portions terminating at end portions, identical cylinder members having first and second surfaces, said cylinder members positioned at each of said end portions and at said apex, said web having a width slightly less than the diameter of said cylinder members, said end portions cylinder members equally spaced from said apex cylinder member at a distance between about 0.10 to about 0.25 of the diameter of said cylinders;
• b) placing at least five of said units against an embankment surface;
• c) assembling said at least five of said units into an interacted relation so that at least three of said five will face in a direction opposite to that of the remaining two of said at least five units;
• and,
• d) repeating the above steps with additional units until the embankment is sufficiently covered.
