How many of us have inspected a house or seen a house that has been refurbished or remodeled after an extensive fire. Here is a possible write up that you may consider when reviewing or commenting on the foundation.
CONCRETE TIP: Concrete or foundation has been subjected to past fire(s) and possible damage.
Fire - When a fire occurs servere concrete damage may occur because of a method known as "heat shocking". In layman's terms concrete expands as it's heated. In the extreme heat of a fire, the outer shell or layer will expand much more quickly than the inner portion, causing the outer layer to fracture and break away. This process is known as "differential expansion". It can also occur in reverse when the fire is doused by fire hoses or sprinkler systems. In this case, hot concrete is cooled suddenly causing the outer layer to shrink and break away.
