  • Very low viscosity
  • Can be used in wet situations (retaining wall)
  • It will bond with the sub soils
physical properties at room temperature
Physical Properties at room temperature
  • Mixing Ratio is (1:1)
  • Viscosity is 300-450 cps
  • It takes about 8 minutes to set
  • Expands at a ratio of 20:1
  • A final strength 90 psi (ASTM D-1621)
installation
