Boulders add focal points to any type of landscape. Smooth, glacially-deposited and multi-colored and available in a wide array of shapes and sizes, boulders are often used in landscaping for retaining walls, man-made waterfalls, water features, shoreline rip rap and as accent pieces. Compared to boulders, cobbles are smaller and are excellent for any water feature projects. Rip rap refers to rocks ranging in shape and in size from 6 to 30 inches in diameter. These are used to protect and stabilize areas prone to erosion, as well as areas with unstable soil slopes and likely to experience seepage. Alexis Trucking supplies a wide variety of landscaping rock products that can be used as great accent pieces. Call us today at (760)508-0409 or (760) 307-5363, or see us at our office.
