    weep holes
  14. Bridging refers to the practice of
    installing bracing between joists to add stiffness to the floor/ceiling
  15. What are some signs of differential settlement
    cracks in interior and exterior walls, floors out of level, doors out of square or rubbing on the jamb, etc.
  16. What is the minimum crawl space access opening
    18in by 24in if no mechanical equipment; 22in by 30in if mechanical equipmen is present in teh crawl space
  17. What is the "drying edge effect" on a foundation
    it occurs when moisture is removed from the soil along the perimter of the foundation
  18. What is spalling
    pieces of concrete flaking off; can be caused by a lack of a moisture barrier, but usually caused by a lack of sufficient cement in the concrete mix
  19. What is efflorescence
    a white powdery substance that forms on brick walls and other masonry surfaces
  20. How does efflorescence get inside a basement
