John Laforme and YC from SoCal Seismic Construction House Bolting discuss foundation issues, emphasizing the commonality of cracks in raised foundations. YC explains that vertical cracks are typically caused by improper drainage and can be repaired with epoxy injection and metal straps. Horizontal cracks, however, indicate foundation failure due to rebar issues. They highlight the importance of proper drainage and rain gutters to prevent foundation problems.

Vertical Cracks

• Common Causes:
  • Settlement of the foundation.
  • Shrinkage of concrete as it cures.
  • Minor shifts in the soil beneath the foundation.
• Are They a Problem?
  • Small, hairline vertical cracks (less than 1/8 inch wide) are generally not a serious concern and are considered a normal part of a building's aging process.
  • Larger vertical cracks, or those that widen over time, may indicate settlement issues or excessive pressure from expanding soil or water.
• When to Worry:
  • The crack widens or shows displacement.
  • Water leakage occurs through the crack.
  • The crack appears suddenly after extreme weather or seismic activity.

Horizontal Cracks

• Common Causes:
  • Lateral pressure from soil outside the foundation, especially in areas with high clay content or frost heaving.
  • Hydrostatic pressure caused by excessive water accumulation around the foundation.
  • Poor drainage or waterproofing.
• Are They a Problem?
  • Horizontal cracks are typically more concerning than vertical ones because they can indicate serious structural stress, such as bowing or bulging foundation walls.
  • Cracks wider than 1/4 inch or those accompanied by inward movement of the wall may signal a risk of collapse.
