EMSCO has a complete line of boulders and stones available in their catalog.
Polymer-made, these rocks have two stakes included so that they are anchored to the ground and remain upright even against extreme thunderstorms and intense gushes of wind. Each artificial rock is durable and resilient, as it is able to withstand extreme weather conditions. This natural-looking rock can also be placed over wells, pipes, pump, sprinkler valves, and other fixtures to block them from sight, thus enhancing the aesthetic of the terrain.
