20mm Wood Fibre Fillerboard - Compressible Joint Filler for Concrete Construction - 150mm x 2200mm - pack of 6

20mm Wood Fibre Fillerboard is a high‑density, compressible fibreboard used as an expansion joint filler in concrete slabs, foundations, ground beams, roadways and structural civil‑engineering works. Manufactured from compressed wood fibres, it provides a durable, uniform and cost‑effective solution for forming movement joints where concrete needs controlled expansion and contraction. Wood Fibre Fillerboard is designed to sit within concrete pours to create a compressible interface that absorbs movement caused by thermal changes, shrinkage and structural loading. Its dense yet flexible composition ensures reliable long‑term performance while preventing cracking or stress transfer between adjacent concrete elements.

The boards are easy to cut, shape and install on site, making them suitable for a wide range of groundwork and civil‑engineering applications. Wood Fibre Fillerboard is chosen for its reliability, ease of installation, and proven performance in managing concrete movement. Its compressible structure helps maintain structural integrity, reduce cracking and extend the lifespan of concrete elements in both small‑scale and large‑scale projects.

CHARACTERISTICS

• Compressible joint filler — accommodates movement in concrete structures.
• Durable wood‑fibre composition — stable, uniform and long‑lasting.
• Prevents cracking — reduces stress transfer between slabs and structural elements.
• Easy to cut and shape — adaptable for site‑specific joint widths and depths.
• Suitable for internal and external concrete works — foundations, slabs, beams and pavements.
• Cost‑effective — economical alternative to cork or polymer‑based fillers.

APPLICATION

• Concrete expansion joints
• Ground beams
• Foundations and footings
• Roadways and pavements
• Retaining walls
• Service yards and industrial slabs
