Product Description

In road construction, Expansion Joint Filler Boards are critical materials used to accommodate the natural movement of concrete slabs due to thermal expansion, contraction, and other stresses. Here's a breakdown of what they are, why they matter, and the types typically used:


What Is an Expansion Joint Filler Board?

An expansion joint filler board is a compressible sheet material placed between concrete slabs or between concrete and fixed structures to absorb movement and prevent cracking.


Why Is It Used in Road Construction?

  • Thermal Movement: Concrete expands in hot weather and contracts in cold.

  • Prevents Cracking: Without joints, slabs might push against each other and crack.

  • Separation: Provides a buffer between concrete and other structures (like bridges, buildings, or manholes).


Common Materials Used

  1. Bitumen-impregnated fiberboard:

    • Traditional material

    • Water-resistant, compressible, durable

  2. Closed-cell polyethylene foam (e.g., EVA foam):

    • Lightweight

    • Flexible and easy to install

  3. Cork filler boards:

    • High compressibility

    • Eco-friendly option

  4. Rubber or neoprene:

    • Used in high-performance areas (like airport runways)


Installation Highlights

  • Placed vertically between slabs before the concrete pour.

  • Must align with the joint and extend the full depth of the slab.

  • Sealed on top with a sealant to prevent water and debris infiltration.


Typical Sizes (May Vary by Project)

  • Thickness: 10 mm, 12 mm, 20 mm

  • Height: Matches the slab depth (e.g., 150 mm to 300 mm)

  • Length: Usually comes in 1 or 2 meter lengths


If you're working on or specifying for a road construction project, I can help you choose the right type of filler board based on traffic load, climate, and other specs. Want to dive into standards or pricing in your area?
