  • Elimination of binding of steel
  • Faster pouring of concrete
  • Faster removal of form work
  • Ease of drilling of concrete with no steel to mount water mains
  • Simple erection and pouring of concrete lid with manhole
  • Corrosion free, leak free solution
  • Minimum downtime and minimum interruption of daily activities
