Duracord is a back-up material manufactured from low-density, closed-cell expanded polyethylene. It is highly flexible, compressible, and offers excellent recovery and tensile strength, ensuring consistent joint performance.
Supplied in various diameters, Duracord is used to control sealant depth, prevent three-sided adhesion, and improve sealant efficiency in concrete joints and expansion joints. Its closed-cell structure makes it moisture-resistant, non-rotting, and suitable for long-term use in construction applications across Johannesburg and Gauteng.
