Rally Sunflex Expansion Joint Foam Filler — closed cell cross-linked polyethylene foam, charcoal grey, zipped 10mm from one edge so the top strip can be torn off after the pour to form a sealant reservoir.
Choose self-adhesive (peel-and-stick backing holds the joint to slab ends or formwork before pouring) or no adhesive (plain foam, fixed manually — suited to coastal and specialty bonding applications).
Fills expansion joint gaps in road, bridge and building construction wherever low-load joint fillers are required. Also works as a backup strip behind sealants in floor and wall joints, and as lagging around pipes and vessels. 75mm x 25m roll.
Pickup at our Howard yard or Fraser Coast delivery.
