Why Use Metal Staples?
Metal staples have long been the anchoring device of choice for contractors. While they have done an adequate job, they are far from perfect.
It takes roughly 2 pound of force to pull a metal staple from the ground since their inherent design lacks any engineered resistance. This becomes problematic as changes in temperature, geographical pressure and tectonics push the staples out of the ground. Over time metal stakes cannot keep the blanket, mat or fabric from being adequately held down. Furthermore, this exposes the staples that have been pushed from the ground to lawn mowers and other machinery that can shoot their debris causing damage or injury.
Because of this tendency to come out of the ground, in order to sufficiently secure the erosion control materials, scores of staples are installed.
