Backing Cord

Backing Cord from Joluka serves as a permanent, preformed joint filler. Manufacturers use low-density, closed-cell expanded polyethylene to produce it. This material makes the cord lightweight, flexible, and highly compressible. It resists moisture and retains its shape after compression. The cord also offers excellent recovery and tensile strength. Builders use Backing Cord in various expansion joints. It supports joint sealants and caulking materials. Contractors apply it in vertical and elevated joints in concrete, brick, and metal structures. It also works well in reservoirs and piping systems. Furniture manufacturers use it in specialised applications. Joluka supplies the cord in 100-meter rolls. Customers can choose from diameters of 6mm, 8mm, 10mm, 12mm, 15mm, 20mm, and 25mm. This range suits different joint sizes and depths. Installers find it easy to handle and position. It helps control sealant depth and prevents three-sided adhesion. This improves sealant performance and longevity. The cord does not rot, swell, or disintegrate. It withstands harsh conditions and chemical exposure. It ensures a clean, professional finish in construction joints. Engineers and contractors trust Joluka’s Backing Cord for reliable joint sealing. It enhances structural integrity and reduces maintenance needs.
