E&M expansion joints are made by means of vulcanized elastomer modules reinforced with embedded steel. Its main function is to allow and control the relative movements between two parts of a structure, whether due to variations in temperature, humidity, and/or movements due to external agents such as vehicular traffic.
Our expansion joints are supplied in modules of a certain length, which are anchored to both sides of the structural joint. We produce a wide range of models that control movements from 50mm to 440mm
