Different factors are responsible for damaged expansion joints. While damaged expansion joints can be blamed on mechanical abuse, poor installation service can also play a culprit in a failing expansion joint. Proper planning and the right material choice are necessary when creating expansion joints. Also, a change in the use of a facility can result in damaged concrete expansion joints. If you change the activities in a facility, the existing expansion joints might not be ideal for the new activities, hence damaged expansion joints. This is a good example of when to seek expansion joint repair.
