Fibreflex Expansion Joint filler (Fillerboard) is made from highly resilient softwood fibres. Resistant to moisture penetration and ice formation in the joint.

Fibreflex fillerboard is also immune to dry and wet rot, fungus attack or similar forms of deterioration.

Applications
Fibreflex has been proved throughout the world on a wide variety of applications. These include joints in traffic surfaces – roads, runaways and pedestrian areas; as a temporary filler in contraction joints; joints in concrete roofs, external walls, cladding and floors; as a filler in structural separation joints between buildings, in brickwork, concrete and building block construction; as separator strips in slab pavement construction, as protection for waterproof membranes against penetration by backfill materials.
