How do I prevent waterfront erosion?

I have had 2 large Gabions fall over onto the beach last fall. I am looking for a solution to keep the materials from eroding/falling. My waterfront bluff is only 15 ' , but with water levels rising on Lake Huron I feel I need to hurry and come up with that solution, any suggestions?

    I think you need to talk to a pro landscaping company that specializes in stablizing shore erosion. It won't be cheap. There may well be local/county/state and even federal regulations that need to be addressed in stablizing the shoreline - as I understand it, typically by trucking in and dumping tons and tons of stone and possibly even building a break-water wall. This was a major issue some years back with property owners in the suburbs north of Milwaukee, WI on Lake Michigan when lake levels started rising after being at historic lows for many years.

    That is serious work! You will need to hire a contractor to bring in heavy rock and place it at the foot of the bank. You may need an engineer to look at the problem and offer the most permanent solution. Any type of plants or small rock will probably wash away. Look to see if others near you have done any projects and ask them how it is working and who did the work.

    Did the Gabion walls have tie backs?

      The Gabions were set on sandstone/slate/earth, ha. a very flat surface. I do not know how many years they have been there, guessing 15 to 20 years. It may be it was at their lifetime. Over the years, I could see the gabions leaning further and further out. I believe the ice and erosion dirt pushing them out. I want to do it right this time, I believe tie backs will be used to help secure them the best.

    We have a pressure treated wood wall with the posts having tiebacks. Our lake is lowered every five years to make necessary repairs. Maybe the bottom layer of the Gabions could be set in some sort of trench. If your lot is flat I don't understand why Gabions were used in lieu of rip rap. Gabions are usually used to line the banks of ditches/canals.
