Yes, foundation damage is most common in older homes. For example, foundations built earlier than the 1950s are very susceptible to cracking and damage, as they were typically made out of unreinforced concrete or bricks / river rocks, held together with simple mortar. Moreover, foundations built during the building booms of the 1950s and 60s are also very fragile, as they were also made from unreinforced concrete slabs as thin as two inches that were poured over unstable top soil that was not properly compacted. As a result, many old foundations are often found damaged today. If you live in an older home, you must inspect the condition of your foundation regularly!
