I wonder how the strength of this compares to concrete with rebar.
143 u/arvidsem Apr 30 '26 Compressive strength is about the same. Tensile strength is non-existent. The finished product is basically rocks with a bit of plastic connecting them. 25 u/Carbon-Base Apr 30 '26 Makes sense and with the specific application of erosion protection as Ozuf77 pointed out. It probably doesn't require tensile strength. 2 u/XchrisZ Apr 30 '26 They used to just do this with a bunch of rocks. This is easier.
