Dirt Screening for Clean Topsoil & Select Fill

Raw excavated soil often contains rocks, roots, construction debris, and other oversized materials that make it unsuitable for use as topsoil, fill, or bedding material without processing. Walberg, Inc. provides dirt screening services that process raw soil into clean, consistent material ready for construction and landscaping applications. We offer both on-site screening at your job site and processing at our Walberg Rock facility in Corning, giving you flexibility to choose the approach that best fits your project logistics and budget.

On-site dirt screening is ideal for projects that generate large volumes of excavated soil that can be reused on the same site after processing. Instead of hauling raw soil off site and importing clean material at significant cost, we bring our screening equipment to your location and process the soil in place. The screening plant separates oversized rocks and debris from the fine material, producing clean topsoil for landscaping, select fill for grading and backfill, and sorted rock that can often be used for drainage or erosion control. This approach can save thousands of dollars in material costs and trucking expenses on large projects.

For smaller quantities or when on-site screening is not practical, we process material at our yard in Corning. You can deliver raw soil to us for screening, or we can haul it from your site. The processed material — clean topsoil and select fill — is available for pickup or delivery back to your project or to another location. We also maintain inventories of screened material available for purchase by contractors, landscapers, and property owners who need quality topsoil or fill material without the wait of processing their own material.

Dirt screening is a natural complement to our excavation, grading, and demolition services. When we excavate a building pad, trench a utility line, or grade a site, the native soil often contains materials that need to be separated before it can be reused effectively. By integrating screening into the overall project, we help our clients maximize the value of their native soil resources while minimizing the cost of importing processed materials. With 26 years of experience in earth-moving and material processing across Tehama, Butte, Shasta, Glenn, Colusa, and surrounding areas, Walberg, Inc. understands how to handle the diverse soil types found throughout the Northern Sacramento Valley and produce consistent, quality screened products.
