Job Stories From Sandy, OR
Settling Sands in Florence

In the northwest we have a diverse climate, terrain and geography. All of these factors affect the types of soils that we have under and around our homes. Two problematic soils that are abundant in Oregon and Washington are clay soils and sand soils. Clay soils are problematic because they are highly expansive and change volume in relation to rainfall or lack of rainfall. Sandy soils too have their concerns because they are easily washed out from under homes during a rainy period, leaving voids for the house to sink in to. Sandy soils are found at the beach, and home owners Lee and Barbara G. of Florence were experiencing soil wash out and a settling foundation.

After inspection by Patrick Dunn, a 6 push pier, upgraded C6 steel system was installed around the settling area of the foundation. By hydraulically pushing the piers through the sand layer to load bearing soil or bed rock, we were able to find a solid foundation to anchor the home to, permanently stabilizing the foundation.

Lee and Barbara now have piece of mind that their home will cease to settle any further and will do so through the tests of time.

Push Piers Stabilize Sinking House in Sandy, OR

David H. has seen his home, year after year, sink and settle. The combination of improperly packed soil around the perimeter and heavy rain fall has created voids under the home which the foundation has settled in to. This is a common event in many homes in the greater Portland area. To the concern of the homeowner, he was worried his home would continue to settle until the foundation had completely failed and found himself with a much larger problem. The solution is simple and it starts with a phone call to TerraFirma.

Adam Lounsbury, upon inspection, noticed significant settlement of roughly 2 inches in one corner of the home. 8 push piers were installed around said corner to permanently stabilize the settlement and restore the strength to the foundation. After proper geo-technical inspection and a stellar diagnosis by Adam, David's home was ready for stabilization. By connecting each pier to a centralized hydraulic system, we were able to achieve proper stabilization evenly throughout the corner or the home. David now has a permanently stabilized foundation, a 75 year warranty and regained piece of mind.

Hood Ct in Sandy
We have a 12' x 13' sun room that has a 1" drop from main house to deck side. The sliding glass door. two windows, and gutter, show the drop, which is making closing harder. Need to fix this before the rain makes the situation worse... Just bought the house a year ago and the problem was not evident to me then. Jonn
in Sandy
We just recently bought a house, and it wasn't until we started putting furniture in it that we realized the house had settled over a beam that is running down the middle of the house. Which we assume is a foundation support. But we just want to have someone look at it and tells us what options we have.
