Bulk Fill Dirt and Backfill Delivery Across the Bay Area

Find fill dirt and backfill materials for your next landscaping or site preparation project. Whether you’re leveling uneven ground, building up landscape areas or filling an excavated space, choosing the right material starts with understanding your project’s requirements. Review each product’s description for its composition and intended uses before ordering.

Fill dirt serves a different purpose from planting soil. For lawns, garden beds and planted areas, plan for a suitable topsoil or planting mix above the fill where needed. Structural backfill, utility trenches and areas beneath paving or foundations may require specific materials, compaction and testing. Follow your project plans and confirm material requirements with your contractor or engineer.
