Expansion Joint Foam Tape

For expansion joints (also called experience joints, control, or movement joints), single sided foam tape acts as a compressible backer. Black expansion joint foam tape is a compressible polyethylene foam designed to back-seal expansion joints, allowing materials to move without cracking or damage. It provides a consistent joint depth, resists moisture, and ensures a clean, professional finish for floors, walls, and trim. Available in various thicknesses and widths to fit your project.
