Expansion Joint Covers: The Hidden Element That Protects Your Building’s Performance

When it comes to modern construction, every detail matters—especially the ones you rarely see. Expansion joint covers may not be the star of a building’s design, but they play a vital role in ensuring safety, durability, and visual continuity. At Heard Group, we engineer expansion joint covers that combine performance with design versatility, meeting the demands of both commercial and industrial environments.

What Are Expansion Joint Covers?

Expansion joints allow for the natural movement of building materials due to temperature changes, structural settlement, seismic activity, or heavy traffic loads. Expansion joint covers are the visible, protective elements installed over these joints, shielding them from wear, debris, water ingress, and trip hazards.

Without a properly designed cover, joints can quickly deteriorate, leading to costly repairs and unsafe conditions.

Why Quality Expansion Joint Covers Matter

1. Safety – Covers create smooth transitions between surfaces, reducing trip hazards in high-traffic areas such as shopping centres, hospitals, and airports.

2. Durability – They protect the underlying joint from moisture, dirt, and mechanical damage.

3. Aesthetics – Modern covers are available in finishes and materials that blend seamlessly with the surrounding flooring or wall system.

4. Compliance – Correctly specified covers meet building code requirements for accessibility, hygiene, and slip resistance.

Choosing the Right Expansion Joint Cover

At Heard Group, we design covers for a range of environments:

Materials That Last

Our expansion joint covers use structural-grade aluminium, 304 stainless steel, and high-quality elastomer seals. We choose materials that resist corrosion, heavy wear, and environmental stress, ensuring the system lasts for decades.

• Aluminium: Lightweight, durable, and anodised for extra protection.

• Stainless Steel: Exceptional corrosion resistance and strength.

• Elastomer Seals: Flexible and weather-resistant, accommodating movement while maintaining a tight seal.

Installation and Retrofit Options

Heard Group designs expansion joint covers that are straightforward to install in both new builds and retrofit projects. Our systems include pre-drilled fixing holes, grooved base tracks to prevent grout intrusion, and continuous anchor legs for consistent performance.

For retrofit projects, we provide solutions that minimise downtime—ideal for live environments like hospitals, shopping centres, and transport hubs.

Common Mistakes to Avoid When Specifying Expansion Joint Covers

• Undersizing the movement capacity – Always allow for maximum expected expansion and contraction.

• Ignoring load requirements – Specify covers that match the traffic type (pedestrian, trolley, or forklift).

• Overlooking surface finishes – Poor finish matching can detract from a building’s interior design.

• Skipping environmental considerations – In wet or outdoor areas, choose covers with superior sealing and corrosion resistance.
