Growtivation SEW102 Siteworx White Foam Expansion Joint Strip 10 x 150mm x 10m

This white foam expansion joint strip is manufactured from polyethylene, offering a flexible solution for movement joints in concrete, brickwork, and blockwork. Supplied in a 10mm thick, 150mm wide, and 10m long roll, it is designed for use where controlled expansion and contraction are required, such as between slab pours or along wall perimeters.

On site, the strip is typically installed to separate new concrete from existing structures or adjacent surfaces, helping to absorb movement and reduce the risk of cracks. Its lightweight and easily trimmed format allows for straightforward handling, while the white colour assists with visible joint placement before concrete pouring or block laying.
