Rip Rap

Rip rap is widely used in erosion control and building design, and we carry high-grade products. The size of the rip rap you select depends on the speed and force at which the water runs through the rock. The slope of the area where you will apply the rip rap is another factor to consider. Although this natural treatment is excellent for many settings, it also traverses very easily, and it’s why we work closely with our clients to assess the gradation and determine which sizes will be suitable for optimum coverage. Most customers also want something that will be easy to maintain with the least trouble for workers. We carry rip rap in 1″- 4″, 2″- 4″ and 4″-10″ size ranges in colors as varied as Kino Blue, Autumn Red, Rebel Red, Beatty Apache Gold, Silverbell Apache Gold, and more, and you are sure to find the hues you want for your project.
