2″- 4″ Armour Rock 50-100mm

This washed, round rock is screened to 2"-4" in size. While it can be used for landscaping purposes to help create the river rock look, its primary use is as “armour rock” for protecting the banks of streams and rivers, or for protecting bridge abutments. Armour Rock’s purpose, wherever it is laid, is to protect against erosion by providing a barrier or “armour” against the elements.
