MEGASEAL CORD is a closed-cell polyethylene foam backing rod designed to support sealants in expansion and construction joints. Available in various diameters, it provides a firm, flexible base that helps maintain proper joint dimensions and prevent three-sided adhesion. MEGASEAL CORD is highly resistant to moisture absorption, weathering, and deterioration, ensuring long-term performance in internal and external joints. Easy to handle and install, it is essential for high-quality joint sealing across construction, civil engineering, and facade applications. It also improves joint movement capacity and reduces sealant strain, prolonging the service life of the sealed joint.
