Shrinkage & Crack-Reducing Admixtures

Reduce and prevent cracks in concrete

Cracks in concrete can be reduced or often prevented by reducing drying shrinkage. Shrinkage-reducing admixtures and the only crack-reducing admixture on the market, MasterLife CRA 007, will reduce drying shrinkage, and minimize time to cracking and width of cracks if cracks do occur, to improve:

  • Water tightness
  • Durability
  • Aesthetics

BASF shrinkage and crack reducing admixtures meet ASTM C 494 and AASHTO M 194 requirements for Type S admixtures.
