WHAT CAUSES FOUNDATION PROBLEMS IN Tri Cities HOMES?

Tri-Cities conditions can affect home foundations in several ways. Dry summers, changing soil moisture, irrigation runoff, seasonal temperature shifts, and drainage problems can cause the soil beneath a home to settle, contract, or move over time.

Common foundation issues throughout Kennewick, Pasco, and Richland include:

  • Cracked walls and uneven floors
  • Foundation settlement and soil movement
  • Sagging floors and weakened crawl space supports
  • Sticking doors and windows
  • Cracked or sinking concrete around the home

Why do TRI-CITIES Homes develop foundation problems?

Foundation concerns in Tri-Cities are often connected to dry conditions, changing soil moisture, irrigation runoff, drainage issues, and the age of many neighborhood homes.

Across Kennewick, Pasco, and Richland, soil can contract during extended dry periods and shift when exposed to irrigation or sudden moisture. This movement can contribute to foundation settlement, wall cracks, uneven floors, and weakened crawl space supports.

Older homes may also have aging structural materials, inadequate drainage, or foundation systems that have experienced decades of soil movement. Professional foundation repair in Tri-Cities, WA can address the source of these problems and help protect the home.

Tri-Cities Soil &
Geology

Foundation problems in Tri-Cities can be connected to variable soil conditions, natural settlement, irrigation, drainage, and the preparation of the building site.


Typical causes of such problems are:

  • Soil composition with clay, glacial till, and fill soils that can shift with moisture
  • Difficult drainage on sloped lots in North Tacoma, South Tacoma, and hillside areas
  • Perched groundwater, compacted fill, and poorly draining soil layers
  • Saturated soil due to Tacoma’s long wet season and Puget Sound moisture
  • Constant hydrostatic pressure against foundations and basement walls

This can lead to foundation settlement, cracking, or basement wall movement in Tacoma homes.

Tri-Cities Rainfall & Water Pressure

Although the Tri-Cities has a relatively dry climate, water can still affect a home’s foundation. Irrigation, plumbing leaks, snowmelt, sudden storms, and poor drainage may allow moisture to collect near the structure.

Some of the elements that cause foundation issues include:

  • Frequent rainfall and extended damp periods from fall through spring
  • Sustained Puget Sound moisture and stormwater runoff
  • Wet soil pushing against foundations via hydrostatic pressure
  • Dry-season soil contraction after months of saturation
  • Continual expansion and contraction under the foundation of the home

Over time, these moisture cycles can contribute to structural movement in homes throughout Pierce County.

Tri-Cities Housing Stock

Older homes throughout Kennewick, Pasco, and Richland may develop structural problems as materials age and the soil beneath the property changes over time.

The following problems are frequently encountered within aging properties in Pierce County:

  • Foundations with inadequate depths based on current standards
  • Decayed crawl space support structures and wooden structures
  • Poor drainage systems
  • Insufficient moisture-proof protection
  • Susceptibility to settling and movement

As a result of such defects, it is common to see problems like sagging floors and cracked walls develop within the aging property.

Tri-Cities Seismic Context

Homes in the Tri-Cities can experience seismic activity from earthquakes occurring throughout Washington and the greater Pacific Northwest.

Potential vulnerabilities include the following:

  • Decaying building foundations and framing systems
  • Foundation settlement or shifting
  • Un-reinforced crawlspaces
  • Old homes constructed before modern earthquake building codes
  • Cracked walls or structural movement

While foundation repair is not the same as earthquake retrofitting, ensuring that an old structure remains stable through foundation repair work can go a long way toward improving its performance during an earthquake.

Common Signs of Foundation Problems in Tri-Cities Homes

FN RES FR Sagging Floor 04 1024x683 1 Foundation Repair in Tri-Cities WA
When the soil beneath a building’s foundation compresses or shifts unequally, it causes parts of the foundation to sink or settle more than others. This uneven settling commonly results in noticeable sloping or uneven floors.
Foundation Settlement

Common symptoms of this problem include horizontal or stair step cracking along the foundation wall, diagonal cracks in the corners, crumbling walls and inward bulges.
Look for spalling cracks or delamination which can impact structural integrity.
Cracks in Foundation and Basement Walls

If your windows and/or doors are sticking, jamming, or your doors have non-functioning locks, you could have a foundation problem. Other common signs include door openings that aren’t square and diagonal cracks at top corners of window and door openings.

These are also signs that soil or hydrostatic pressure outside the foundation walls could lead to foundation failure.

Foundation Settlement

In case the soil under the foundation gets compressed or moves in an unequal manner, it leads to differential settling or sinking of different areas of the foundation. Differential settlement often causes sloping of floors.

REVIEWS

Don’t take our word for it – see what our clients have to say.
From Tacoma to Seattle, Portland, and across the Pacific Northwest, our Foundation Repair work speaks for itself

Pat was so good not only at his job, but is an extremely personable type of communicator, is polite and most of all knowledgeable. I’d say he is going places with this company! It is hard to find adequate people these days, let alone someone who is capable of carrying on an educated and informed conversation while listening to my questions and concerns , then actually (past 5 pm on over-time) taking the time to explain them. He was patient and kind to both me and my young daughter. I appreciated his honesty about working with connected buildings, even if it risked new business for his company. If he isn’t already a manager, he soon will be! If you call Terra Firma i’d suggest asking for Par and if Pat works for you, I’d suggest a raise next review!! lol
From bid to project completion, this team has been fantastic. Derek took the time during th ebid process to explain what I needed and why I needed it. He treated me like a compentent human and gave me the info necessary to make a good decision. The crew of guys who did the work were fantastic. It's never easy to have people in your home, but Aris, Fernando, and Tyler were hard-working, gracious, and willing to keep me informed about each stage of the process. This was a significant improvement over our former crawlspace techs and we couldn't be happier. Thanks, guys!

We had a phenomenally difficult issue in a basement. We purchased the home in an estate sale through an attorney so no disclosure was made that the basement flooded with up to 4 feet of water in the winter. Called multiple different foundation system contractors, nobody wanted the job. Terrafirma came out estimated through job and did all the work on time and in budget. Made the renters happy also . I am impressed. Dr. Mary Fitzpatric

We had a great experience with the Roseburg TerraFirma team. Very easy to work with. They explained each process they were going to do in as much detail as I needed. They were able to get the work done sooner than originally thought which was very nice!! They arrived on time each day, ready to go!! Did an outstanding job! When they were done, everything was cleaned up and back to normal. I would highly recommend them!!
I don’t usually do reviews but in this case people should know this is a first class company. Great communications and no selling you on something you don’t need. John was very professional, he spent time with us expanding what issues he did find, measured the level of the floors, inspected under the house and checked wall and foundation cracks. He also placed a blanket down to collect any dirt from entering and exiting the crawl space inside the house. I highly recommend John from the Eugene office and TerraFirma.

We had two companies come and provide evaluations of our foundation repair needs. TerraFirma was by far the most professional and responsive company. In the end we did not go with the lowest bid but we did go with the company that provided the most professional response and gave use the most confidence it would be done right. We were not disappointed 🙂
