Description Product Overview ARDEX RA 144 is a two-component, low viscosity, high modulus structural epoxy adhesive designed for crack injection and concrete repair applications. Its fluid consistency allows it to penetrate fine to medium cracks, providing effective bonding and structural reinforcement across concrete substrates. The system is suitable for horizontal gravity-feed and pressure injection methods, making it ideal for repairing cracks typically ranging from approximately 3mm to 6mm. It also functions as an epoxy resin binder for mortar repairs when mixed with aggregate, allowing use in patching and surface restoration applications. ARDEX RA 144 delivers reliable bonding and sealing performance for both internal and external concrete slabs. Key Features Low viscosity for effective penetration into cracks High modulus epoxy for structural bonding strength Suitable for cracks approx. 3mm to 6mm Compatible with gravity-feed and pressure injection methods Can be used as epoxy mortar when combined with aggregate Strong bonding and sealing performance Suitable for internal and external applications Solvent-free formulation Applications Injection repair of medium-width cracks in concrete Structural crack repair in slabs and masonry Gravity-feed repair for horizontal cracks Pressure injection repair systems using ports Shear fracture repair in concrete slabs Epoxy mortar repairs when mixed with aggregate Notes Mix two components thoroughly before application Apply via gravity-feed or pressure injection depending on application Suitable application temperature range approx. 10°C to 35°C Working time approximately 20 minutes Ensure cracks are clean, dry, and free of contaminants Use injection ports for vertical applications where required Allow full cure before applying load or finishes Technical Information Technical Specifications: Type Two-component structural epoxy adhesive Viscosity Low viscosity Crack Width Range Approx. 3mm – 6mm Working Time Approx. 20 minutes Full Cure Time Approx. 24 hours Application Method Gravity feed or pressure injection Substrates Concrete and masonry Location Internal and external Temperature Range Approx. 10°C – 35°C Colour Amber tint Packaging 470ml dual cartridge This epoxy system is designed for structural crack repair where deeper penetration and high bond strength are required. It provides a reliable solution for medium-width cracks and concrete repair applications across both residential and commercial environments.
