SEALTIGHT CORKFILL Expansion Joint Filler is composed of a shock-proof mass of clean, regranulated cork particles uniformly combined with pure-blown asphalt. This asphalt-cork composition is formed under heat and pressure between two asphalt saturated felt liners. The construction is very similar to SEALTIGHT ASPHALT Expansion JointFiller.
