  • Concrete / screed quality (strength class)
  • Entire structure (sealing of earth-coupling)
  • Concrete age
  • Absence of cracks
  • Joint layout (construction joints, control joints)
  • Type of mechanical or chemical concrete post-treatment (KORODUR, impregnation, curing)
  • Evenness and grading
  • Concrete formula (avoiding alkali–silica reaction and osmosis)
