Job Stories From Astoria, OR
Stabilization Allows For 2nd Level Addition

Soil settlement happens for a variety of reasons. One major reason is simply the underlying earth cannot support the weight of the house. Gradually with time and weather, the soils continues to shift and soften allowing the weight of the house to sink itself. Astoria, Or and any Oregon coastal city is known for having soft soils that settle more rapidly than say the soils found in Portland. The combination of sand and clay make this process inevitable. Lewis D. saw similar soil condition in his Astoria home. His plan was to build a second story to his home and was concerned about the weight being too much for the supporting soil, and he would loose the house to foundation failure just as quick as he built it.

Lewis' and our goal was the same, provide enough stabilization and strength to the foundation in order to permanently stabilize the existing house and the addition. The solution as actually quite simple. By installing a full perimeter piering system including 26 push piers to stabilize vertically, and 3 helical anchors for horizontal stabilization, we were able to achieve enough load strength the support his addition and permanently stabilize the entire structure.

Lewis is so happy now. His existing foundation is now permanently stabilized, and can feel comfortable his home will hold up after his new additions.
