Western Materials offers all types of base, cobbles, and rip rap. Base has many construction fill, compaction, and stabilization applications in road and highway construction, around underground structures, under foundations below buildings and homes, and for driveways and pathways. Our cobbles and rip rap are used for residential and commercial landscaping, slope stabilization, containment, and erosion control around roads, highways, lakes, and beaches.
Rip rap acts as a top layer of loose, angular stone used to resist erosion. Commonly used for riverbanks and stream stabilization, it prevents soil migration and supports landscape longevity. A graded mixture of stone sizes is essential for effective installation, and a filter material underneath helps ensure soil retention. For effective application, the layer should be about twice as thick as the largest rock size.

FAQ
Answers to common questions about cobbles & rip rap.
Rip rap needs a graded mix of stone sizes and a filter layer underneath to work well; if undersized or poorly installed it can shift. It’s also heavier and less uniform-looking than some engineered alternatives.
Hard, angular, durable quarried stone (such as granite) graded across a range of sizes resists erosion best. The largest rock should suit the water flow, and the layer should be about twice the largest stone’s thickness.
Rip rap is cost-effective for erosion and slope protection. Pricing depends on rock size, quantity, and haul distance — larger boulders and longer hauls cost more. Ask for a free quote sized to your site.
