  • Utilize water/cement ratio ≤ 0.42 and high range water reducer (HRWR)
  • Include the use of an integral watertight admixture
  • Design low shrinkage concrete and prevent drying shrinkage cracks
  • Consider the environment & materials, utilize corrosion control and/or ASR Control if necessary
  • Utilize SCC to ensure good consolidation in general and around waterstop
