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.

Home is 118yrs old with basement wall moisture and stability concerns.
in Astoria
Trying to sell a home built in 1918, located in Astoria on the south side. When we purchased the home, 2 years ago, there were no major issues regarding the foundation other than cracks from being almost 100 years old. A recent inspection has said that the foundation has issues. We would like to know what issues are truly a concern or just age. Thanks for your time.

I am interested in getting an estimate for water proofing my basement. Thank you.
in Astoria
The southwest corner of my house (built in 1905) is sinking due to earth movement. There are two helical piers already in place that were installed as a safety measure when the neighbor was installing retaining walls that may simply need to be adjusted. There is significant cracking in the walls and floor in the basement that has worsened over the winter.
in Astoria
Front porch needs reinforcement in order to repair retaining wall.
Old Bridge Lane in Astoria
The foundation is piecemealed together various depths, no vapor barrier, parts are sagging. Joints have been sistered badly. Most is post and pier with wood to earth contact. The home was built in 1939 suffering a fire in 2001 and then an addition added on during the rebuilding. Thanks!
