Description :

Sikacrete®-401 Rapid is a cement based, polymer modified, one-component, fast setting repair mortar containing silica fume and high range water-reducing agents, meeting the requirements of Class R4 of EN 1504-3. Formulated for machine applications using the dry spray process with set accelerators.

Uses :

• Large scale repairs of weathered, cracked, spalling and / or damaged structural concrete.
• Highway works.
• Bridges (columns, piers, sofits, beams, parapets, abutments, etc.).
• Marine structures (quays, piers, jetties, sea walls,
