There are many types of expansion joints. This guide will help you understand the differences, so you can make an informed decision for your next construction project.

The Importance of Expansion Joints on Concrete Bridge Decks

Posted by Brock Peterson on Jun 12, 2018 9:43:24 AM

The two major causes of joint failure are improper installation and insufficient maintenance of the joint. Oftentimes, when dirt, dust or other types of debris build-up in and around these joints (caused by traffic and environmental conditions), the joints lose their ability to expand and contract with the structure, rendering them less effective. When this happens, the reduced flexibility will result in cracking or distortion/crushing of the joint material, compromising the entire bridge’s structural integrity.
