Expansion Joint Floor Cover
Choose the right cover system


Only we can prove our solutions will work for your specific project requirements.



Our expansion joint systems and solutions go through a rigorous series of in-house cycle testing so you don’t have to worry about failures after installation.


Fire tested, peace of mind. When it comes to fire testing, our solutions must pass a series of cycle tests prior to surviving the inferno.


Wind can be a devastating opponent in certain locations. We can prove that our solutions can withstand the strongest winds at our in-house wind tunnel.
