Foundation Inspection in Beaverton, OR
Beaverton subdivisions were built across several decades on ground that was graded to produce level lots, and the recurring foundation issue is the consequence of that grading: part of a house bearing on cut ground and part on placed fill, settling at different rates.
What makes the Washington County version distinct from the same problem elsewhere is the rainfall. Fill that would consolidate slowly in a dry climate is saturated for a large part of each year, and saturation both accelerates consolidation and softens the fill's bearing capacity while it lasts. Movement here tends to be seasonal in rate as well as cumulative in effect.
That produces a diagnostic opportunity. A house on fill in this climate often moves measurably more through a wet winter than a dry summer, so two readings taken in different seasons can establish not just that a house is moving but that water is driving it — which changes the remedy from foundation work to drainage work.
What We Look At Here
- Floor elevation survey mapping the settlement profile across the footprint
- Whether the pattern indicates a cut-fill transition beneath the footing
- Seasonal variation in rate where a second reading is available or worthwhile
- Site drainage: grade, downspout discharge and any water routed toward the foundation
- Crawl space or basement walls for lateral movement accompanying settlement
- Slab-on-grade sections, where movement presents differently from a framed floor

Questions
Frequently Asked Questions
My Beaverton house seems worse every winter. Is that a foundation problem?
It may be a drainage problem presenting as one. Fill under a graded lot loses bearing capacity when saturated, so movement that accelerates each wet season points at water management before it points at the foundation itself.
