The causes of foundation settlement are rarely due to the design (or under-design) of the structure itself. More commonly, damage is caused as changes occur within the foundation soils that surround and support the structure.

Weak bearing soils, poor compaction, changes in moisture content, maturing trees and vegetation and soil consolidation are then main reasons foundations settle, crack and sink.

Your system design specialist will determine what the probable foundation failure causes are and exactly how to fix and prevent further movement of the structure once and for all!

TerraFirma Foundation Systems will provide a Free Written Estimate for your foundation repair and serves many territories throughout Oregon and Washington State.
