Common causes of foundation cracks

The reason behind a cracked foundation slab in residential buildings in Seattle, WA, can vary. Some of the most common causes are listed below:

  • Tree roots: Roots draw moisture out of the soil under the foundation, causing it to shrink and sag, leading to a breakdown of the underlying structure. Tree roots can also cause cracks in sidewalks and patios.
  • Settlement: Basically, the house’s foundation is built on the ground. If the soil is not consolidated, the weight of the house will cause the soil to settle. Differential settlement causes foundation cracks.
  • Expansive soil: This geological feature indicates that the ground swells when wet and contracts when dry. Soils containing high clay contents can pressurize the foundation and cause it to crack in the dry season.
  • Drainage failure. Poor drainage leads to excess water pooling around the foundation is the primary culprit of foundation cracks.
  • Leaking plumbing. Leaking water moistens around and under the foundation, which, over time, develops cracks.
  • The design and size of the foundation are not suitable for the type of soil, and the load that the foundation is carrying will create cracks. Building more floors is one example.
  • The foundation structure does not have enough reinforcements to make it solid and secure.

What are the signs of a foundation crack?

Foundation cracksThere are numerous indicators that homeowners can observe to identify a crack in the foundation of their home. Here are some warnings that your home needs the assistance of foundation crack repair professionals:

  • Wall Cracks – Cracks in drywall jagged and oozed at a 45-degree angle, grout cracks, and cracks in the door and window corners.
  • Self-closing or opening doors or sticking or rubbing doors and windows indicate that the frame has twisted due to foundation subsidence.
  • Sloping and cracked floors are signs of shifting and changing foundations. One side of a sloped or cracked floor is lower than the other.
  • If water gets into your basement or crawl space, it could mean that your foundation might have large cracks.
  • Bowing or inclined walls: hydrostatic pressure caused by excess water around and under the foundation pushing against the wall causes it to curve or tilt. In addition, some other signs, such as missing or cracked floor tiles, cracks in the garage floor or concrete slab, creaking floors, chimneys leaning away from the house, and so on, are also things you should watch out for.

The potential risks of leaving foundation cracks unrepaired.

Home foundation cracks can vary in terms of appearance and have many potential risks if not handled in time and properly. It requires professional knowledge to determine the type of damage they will incur. Experts point out some of the dangers associated with unrepaired foundation cracks, as follows:

  • a damaged and unattractive exterior. As mentioned, foundation cracks can cause cracks in floors and ceilings, tilting walls, and uneven floors. If it is not repaired, the house’s aesthetics will be significantly affected. In case the owners want to sell or rent, of course, the damage to their economic profit from the real estate will be much greater than the investment in the repair.
  • Water infiltration and moisture problems Foundation cracks allow water and gas to seep into the basement, even insects. Water can also pass through cracks in ceilings and windows. Humidity and mold cause unpleasant odors, and home furniture is at risk of deterioration and damage. In the long run, if left untreated, this situation worsens. As a result, water seepage can cause the concrete structure to become porous, negatively affecting its solidity.
  • Structural problems. Compared to large-scale buildings, home foundation cracks do not pose any immediate risk, but the structure’s durability will be affected. It gradually weakens around the crack due to the accumulation of moisture and foundation porosity, especially if the crack is in the bearing part of the foundation.
  • Health risk. Cracks in the foundation act as an entry point for moisture, creating a high-humidity environment that is ideal for mold growth. This is a great concern for residents living in the house with health problems related to the respiratory tract and allergies.
