The 100mm Fillcrete Brickfill Foam Expansion Joint Roll (12mm x 10m) is a specialized low-resistance cellular expansion joint filler designed to accommodate structural movement in brick and blockwork applications.
 
Manufactured from high-quality closed-cell cross-linked polyethylene foam, this lightweight roll features very low water absorption and strong resistance to oil, ozone, and weathering. It incorporates a convenient scored tear-off strip, allowing it to be built flush into masonry and cleanly stripped back to create a uniform depth for final sealant application without requiring a separate bond breaker.
