EXAFOAM HD is a high-density close cell polyethylene fillerboard which is used to form and fill expansion joints between adjacent cast in-situ concrete. When installed it provides excellent support to join sealants and is particularly suitable for application in water retaining structures.
EXAFOAM HD is used to fill expansion joints, particularly where greater support to sealants is required to withstand hydrostatic pressure, this makes it particularly suitable for water retaining structures.
