5 Must-Have Features in a Expansion Joints Supplier

Every expansion joint is not created equal. There are countless variations in substrate conditions and transition options that must all be considered to ensure a safe and long-term solution. For horizontal joints, contractors, architects and manufacturers should remember these 5 things to safeguard their new construction and restoration projects from failure and mitigate risk.

1. Investigate Existing Conditions

Examine the site and take note of the following:

• How many expansion joints there are and the distance between them. For example, if expansion joints are 100 yards apart, expect high force and movement concentrated in the existing joints.
• How big is the throat opening? Some products can only accommodate certain sizes so take note of the width of each joint.
• Look for cracks and scratches in the concrete. In circumstances of a metal plate system, extreme movement may result in scratches in the substrate. If you see these, consider an alternative method for restoration.
• Determine (and validate) joint movement. Measuring joint movement can be difficult, especially in new construction. Reach out to the structural engineer and refer to local codes to confirm expected movement and what is permitted in your area. Validate this by using a scratch gauge or hiring a consultant. You do not want to compound a mistake, so ensure you have all the accurate information before making any recommendations.

2. Determine anticipated and potential traffic

Expansion joint solutions can handle varying degrees of pedestrian and vehicular traffic. Consider the extreme instance of a snow plow or even a fork lift where a big gap could cause it to drop pallets. If you have a wide joint in an area where you don't expect foot traffic, there is still the possibility for someone to walk by and get injured if the conditions are not secure. High heels can also puncture a system if not accounted for. Consider the full potential before choosing a solution.

3. Does your project require a tie-in to the deck coating?

In parking garages and warehouses, you may need a seamless transition of your expansion joint. If this is the case, you may need to look into fluid-applied solutions.

4. Special Project Requirements

Are there any special requirements to accommodate such as fire rating, food safety, seismic movement, sound transmission or pick resistance? Some projects, such as prisons or schools, will require more stringent characteristics of your transitions. Perhaps there are irregular shapes that your solution must span. Make sure your expansion joint can match these and that your manufacturer has proven success to share with you and your client.

5. Understand Your Options

Many industries regularly cope with stresses in their piping systems. But they usually turn to a common solution: expansion joints. Read below to learn about five industries that rely on expansion joints and how they use them in their work.

Construction

One industry that relies heavily on expansion joints is the construction industry. Builders regularly participate in projects that require the use of steam and hot water, which can cause thermal growth in piping systems.

This growth makes the use of an expansion joint very helpful. Builders will turn to products that range from basic joints to extremely pressurized ones so they can cope with thermal expansion while also completing the job satisfactorily for their clients.

Oil and Natural Gas

Two other sectors that depend on expansion joints are the oil and natural gas industries. These businesses use many joints and flex hoses to build systems in all aspects of their operations, including exploration, refining, and distribution.

In addition, joint manufacturers can build products for transition lines that absorb substantial amounts of movement. They can also serve the oil and gas industries by retrofitting their clients' existing designs with new tie rods and other features.

Manufacturing and Processing

The manufacturing and processing sectors also have a use for expansion joints. Every day, companies in these industries deal with thermal expansion and thermal cycling. Joint manufacturers can create custom products to help them with their specific applications.

Power Generation

Another industry that relies on expansion joints is the power generation sector. Clients in this industry use custom-made expansion joints to conquer the challenge of misalignments due to their tanks or equipment settling. Manufacturers can also design their products to enhance the cycle joint's life while staying dependable to users.

Wastewater Treatment

Wastewater treatment is another sector that has a need for expansion joints. Plants need to use metal joints to cope with the corrosive elements and acidic conditions that are in the treatment process. Fortunately, joint manufacturers can build products with different alloys and features that make them tough enough for these processes.
