SikaEmaco® S 488 (formerly known as MasterEmaco® S 488)

Dual shrinkage compensated, trowelable fibre reinforced thixotropic repair mortar


MasterEmaco S 488 is a pre-bagged ready-to-use structural repair mortar in powder form. When mixed with the correct amount of water, it produces a thixotropic, high strength repair mortar, reinforced with acrylic polymer fibre. It possess excellent bond characteristics to steel reinforcement and to concrete. MasterEmaco S 488 mortar is shrinkage compensated. It has low permeability and is extremely durable. MasterEmaco S 488 contains no metallic aggregate and is chloride-free. MasterEmaco S 488 is formulated for sprayed or trowelled applications – in thicknesses up to 50 mm in one layer by hand application. Greater thicknesses can be achieved when spray applied.

TYPICAL APPLICATIONS


  • All types of structural repair which can be applied by trowel or wet spray
  • Repair of structural members subjected to repetitive loading
  • Repair to reinforced or pre-stressed beams or columns
  • Protection of concrete subject to attack from water containing chlorides and sulphates, etc.
  • Repairs in industrial areas, especially those containing mineral oils and lubricants
  • Repairs in marine environments

ADVANTAGES 


  • Shrinkage compensation – reduces the risk of cracking due to shrinkage and ensures full contact with host concrete and load transfer in structural repair situations
  • No primer required – allows rapid application at reduced cost
  • Can be spray applied – rapid application of large quantities
  • Low rebound – when spray applied rebound is minimal, with subsequent saving in material cost
  • Extremely low permeability – gives excellent resistance to attack by aggressive elements
