SpECcord Closed Cell Polyethylene Back-up Rope

SpECcord is a high-performance closed-cell polyethylene back-up rope specifically engineered to work in conjunction with SpECseal polyurethane sealants. It serves as a critical component in the SpECseal system, ensuring optimal sealant performance, proper joint depth, and a clean, professional finish in construction and industrial applications.

Unlike open-cell materials, the closed-cell structure of SpECcord prevents the sealant from being absorbed into the back-up rope. This characteristic ensures that the polyurethane sealant remains at the surface where it is needed most, providing superior adhesion and long-lasting protection against water, air, and dust infiltration. The material is non-absorbent, dimensionally stable, and resistant to chemical degradation, making it ideal for demanding environments.

Key Features

• Closed-Cell Structure: Prevents sealant absorption, ensuring maximum material efficiency and consistent joint profiles.
• Chemical Resistance: Inert to most sealants, solvents, and environmental factors.
• Dimensional Stability: Maintains its shape and size under varying temperatures and humidity levels.
• Easy Application: Flexible and easy to handle, allowing for precise placement in joints of varying depths.

Applications

SpECcord is widely used in conjunction with SpECseal 625HD and other SpECseal products for:

• Sealing expansion and contraction joints in concrete structures.
• Waterproofing applications in basements, tunnels, and underground structures.
• Industrial flooring and deck joint sealing.
• Construction joints in bridges, dams, and heavy civil engineering projects.
