Pre-construction site preparation with grading stakes and soil compaction equipment

    Utility Trenching

    Utility trenching is the foundation of every functional property—delivering water, power, sewer, and communications below grade where they're protected from weather and equipment. Tacoma Creek Build Co. provides safe, code-compliant trenching services across Spokane, Newport, Coeur d'Alene, and Sandpoint, handling depths from 18 inches for electrical conduit to 4+ feet for water lines below frost. Our crews coordinate with 811 locates, use trench boxes for safety, place proper bedding for pipe support, and compact backfill to prevent settling—ensuring your utilities stay buried, functional, and passing inspection for decades.

    Mountain sites present unique challenges: shallow bedrock requires hydraulic breakers, steep slopes demand careful excavation angles, and freeze lines run deeper than lower elevations. We've trenched through Bonner County timber lots, rocky Pend Oreille ridges, Kootenai County hillsides, and Spokane suburban tracts—always with precision, safety, and attention to code. When you need reliable land clearing and site prep before trenching, we handle that too, delivering full-scope site development from first cut to final compaction.
