100mm x 25m Adhesive Backed Expansion Foam

100mm adhesive expansion joint is a closed-cell foam jointing for creating an expansion void in movement joints. The adhesive back makes it easy to adhere joint to walls or slab ends reducing the need for additional fasteners. The expansion joint is zipped at 10mm meaning that once the concrete has been poured, the top 10mm can be torn off leaving a void for joint sealant.
