When it comes to stadium design, expansion joints are essential. These massive, high-traffic structures endure constant stress from weight, weather and movement. Expansion joint covers and seals used in stadium applications are designed to absorb those forces, stand up to heavy foot traffic and help safeguard tens of thousands of people at once.

Roof expansion joints are essential to any roofing system, designed to absorb movement from thermal shifts, seismic activity and structural settling. 

Expansion joints aren’t just a building necessity — they’re a design superpower. When used strategically, they become one of the most powerful tools architects and builders have for ensuring both resilience and performance in the building envelope.

3 Types of Fire-Rated Expansion Joint Systems

In most commercial buildings expansion joints are a fact of life.  These joints are necessary to accommodate expected building movements due to thermal changes, wind sway and differential movement typically caused by seismic events.  When these joints occur in a fire-rated floor or wall a product or system must be used that has been rated to that same level.  This means if the joint occurs in a 2-hour rated floor assembly the expansion joint system used to fill the joint must also be rated for 2 hours.  Per current building codes, these joint assemblies must be tested at an accredited testing agency such as Underwriters Laboratories or Intertek and be tested in accordance with ASTM E-1966 or UL 2079 test standards.

Ensure compliance and long-term durability.

Ensuring effective moisture management in your building project is crucial, especially when it comes to expansion joints. Moisture infiltration poses a significant threat to the structural integrity of a building, making it imperative to implement proper drainage solutions. To guide you through this process, here are five key considerations you should keep in mind:

Important Questions You’ll Want to Ask: 

One of the requirements for large, commercial buildings is the ability to move without damage. 

While it may seem like a small detail in the grand scheme of construction, picking the right expansion joint covers will help ensure the building’s structural integrity. 

Ceiling expansion joints are essential in building design, especially when working with large or multi-structure buildings. 

You don’t really see them, but concrete floor expansion joints are a big deal in commercial buildings. They’re one of those hidden things that keep the place solid and safe. Picking the right ones can make a huge difference in how long your floor lasts.
