Expandafoam - Closed Cell Polyethylene Joint Filler

Expandafoam is a closed-cell polyethylene joint filler for use as an expansion joint filler in brick and blockwork, isolation joints and as back-up strips for elastomeric sealants placed in narrow joints in concrete floors subject to foot traffic and light wheel loads. Key advantages include readily compressible material, low load transfer, easily cut on-site, excellent recovery after compression, non-absorbent, rot proof, CFC free, and fast simple application with no special tools, heating or drying required. Flexible, long lasting, self-sealing to minor substrate blemishes with high puncture resistance and joint water pressure resistance.
