EXPANSION JOINT SURVEY DETAILS
We review installed expansion joints to verify that they are being used correctly and that they are in good working condition. Many times expansion joints are squirming, sagging, leaking, or corroding, indicating that they are near the end of their service life, or that they have been used in the wrong service or loading application. Unfortunately, there are many misconceptions about expansion joints that cause them to be used incorrectly and then add to the stereotype that expansion joints are inherently problematic, when in fact, when properly designed and installed, expansion joints often outlast the piping system they are installed in.
