Foundation cracks can occur due to various reasons, including: Settling : As the soil beneath a foundation settles or shifts, it can cause cracks in the foundation. Poor orignal construction : Improperly mixed or insufficiently cured concrete, or inadequate reinforcement, can cause foundation cracks. Water damage : Water can seep into the soil around the foundation and cause it to expand and contract, leading to cracks. Tree roots : Roots from nearby trees can grow into the foundation and cause it to crack or shift. Temperature changes : Extreme temperature changes can cause concrete to expand and contract, leading to cracks in the foundation. Here in Lincoln where we have cold winters and hot summers, we see foundation problems due to temperature changes. Improper drainage : Poor drainage can cause water to collect around the foundation, leading to cracks. Earthquakes : Seismic activity can cause the ground to shift and lead to foundation cracks.
