What is a likely cause of the foundation crack shown here i this home built in a cold climate?
a. Water leaking from the faucet saturated soil beneath the foundation. The saturated soil expanded as it froze, cracking the foundation.
b. An improperly located joint between wall logs has weakened the wall structure, placing excessive weight on the foundation at this point.
c. Excessive cracking of wall logs has weakened the wall structure, creating a point load that has resulted in foundation cracking.
d. Inadequate footing depth/width resulted in a foundation wall that was too weak to support heavy snow loads.
