Why is my foundation Settling or Sinking?
Certain types of soils in the Pacific Northwest absorb water and expand, exerting significant pressure against the foundation, causing it to move creating cracks in the foundation or gaps in your floors.
Consolidating soil causes soil to shrink and compact. This undermines the foundation, making it unable to support the weight of the house evenly. Houses built on hills or with a hot, southern-facing exterior are particularly susceptible and commonly present issues such as sticky doors and windows.
Water can seep in through cracks in the floor or walls of a basement, expanding and putting pressure on the concrete. Water and moisture issues can create water stains, cracks, misaligned floors and doors throughout your home.
Improper drainage, like clogged gutters and downspouts pointed toward your home can cause soil erosion around the foundation allowing water to seep into your basement.
Cheap building materials, poor planning, and shoddy work all spell trouble for a home’s foundation. Inaccurate grading, poorly placed structural reinforcements, and not properly compacted soil can all cause damage.
Trees planted too close to your foundation can pose a slow-growing problem. Roots, seeking water, force themselves between hairline cracks in concrete. The roots of mature trees expand and contract as they soak up water, displacing the earth underneath a home’s foundation.
