Gabion wall repair - toe reinforcement
(OP)
Does anyone have experience with repairing gabion walls that have rusted and failed at the bottom? We have many sites throughout the St. Louis area where the bottoms of the baskets have rusted and opened, even with the coated baskets, because the coating gets knicked during construction or by gravel flowing along the stream, then the road salt takes care of the rest. In some places, the rocks have washed out and now the upper baskets are "hanging", but have not failed. In these locations, we were hoping to repair the toes, but with something other than gabion wire, since it will likely fail again. One idea was to form a concrete toe with a flowable fill, but not sure if that would be permittable or if it would have enough compressive strength to hold the weight from above.
Any help is greatly appreciated!

Unfortunately, most of the rocks have washed out. The stream has a bedrock bottom, so the baskets do not extend below grade. The wall is approximately 6 to 9 feet high. How would you drive rails? Something thin enough to get through the basket holes, I expect?

We were theorizing that we could isolate the area with sandbags or something less permeable and pump out the water until the grout cures. As you can see, there is not much base flow. The problem would be if there was an unanticipated rain event.
Any other thoughts besides grout/concrete?
Thanks again!
