Foundation Excavation in Portland, Oregon

Foundation excavation is the process of digging and removing soil to create the space where a building's foundation will be poured. This includes excavating to the correct depth, width, and grade specified by the structural engineer or building plans. It also involves establishing proper drainage slopes away from the foundation and preparing the base with compacted gravel or fill as required. The quality of the excavation directly affects the integrity of the foundation — and by extension, the entire structure.

You need foundation excavation when you're building a new home, when you're adding a room, garage, or second story that requires a new foundation, when you're building an ADU (accessory dwelling unit), when your existing foundation needs to be replaced or underpinned, or when you're constructing a commercial building.

Foundations are unforgiving — there's no room for "close enough." Our crew excavates to exact specifications using laser-guided grading equipment. We understand Portland's variable soil conditions and know when additional compaction, drainage, or soil remediation is needed. We coordinate directly with your general contractor and foundation sub to ensure a seamless handoff.
