How fast ROP (Rate Of Penetration) does Wassara drill in competent rock and other softer formations when drilling in dams?


The ROP is depending on rock/soil conditions. According to our project experience, the ROP usually varies in general as follows:

  • In competent rock: 0.3-0.7 m/min
  • In loose soil the ROP could be 1-1.5 m/min
