SikaGrout®-212 Sealing

SikaGrout®-212 Sealing is a ready-to-use, shrinkage-compensated, high-performance hydraulic mortar. After mixing with water, it forms a fluid mortar suitable for sealing, wedging and assembling industrial and structural elements. Free from chlorides and oxidizing metal particles, it protects steels from corrosion thanks to its basic pH. It ensures a durable monolithic connection, resistant to shock, vibration, humidity and temperature variations. Areas of application Sealing anchor bolts or concrete bars Precision sealing of industrial equipment subjected to shock or vibration Sealing of railway rails or overhead cranes Timing of turbines, alternators, compressors, generators and machine tools Wedging of beams and construction of bridge bed bases Assembly of prefabricated metal, reinforced or prestressed concrete elements Features and Benefits Shrinkage compensated thanks to a programmed and controlled expansion system Excellent adhesion to concrete, mortar and steel Very high mechanical resistance in compression and bending, even in the short term Resistant to sea water and sulfate waters Pumpable, injectable, vibrable and compactable Long-lasting protection of reinforcements against corrosion Rapid commissioning of equipment thanks to its high initial resistance Approvals and standards CNERIB minutes DTEM/44/2013 Technical information Chemical base: Cement, quartz sand and additives Appearance / Color: Gray powder; after hardening: concrete gray mortar Packaging 25 kg bag Preservation 12 months in original, unopened packaging Storage conditions Protected from humidity Store in the original closed packaging
