Growtivation SFB121 Fibre Expansion Joint 2440 x 100 x 12mm

This bitumen-impregnated fibre expansion joint is supplied in 2440 x 100 x 12mm boards and is used to form movement joints in concrete slabs, pavements and hard landscaping works. The material absorbs movement from thermal expansion and contraction, helping to reduce the risk of concrete cracking or surface damage over time.

On site, these boards are typically installed between concrete pours, at slab edges, or alongside kerbs and other fixed structures. Straight edges provide a neat finish and help maintain uniform joint width, while lightweight construction makes handling and cutting straightforward for efficient use on civil engineering and construction projects.
