Slurrex BS

producto exsa

EPumpable matrix emulsion for tunneling, ideal to reduce handling and operation risks because the explosive is formed upon being injected into the boreholes. This allows for reduced loading times and thus faster completion of the work. Its high energy power makes it ideal for small diameter holes (2 inches).

  • High versatility, can be used in rocks of varying toughness.
  • Its density can be regulated according to the project’s needs.
  • Excellent water resistance.
  • When sensitized within its detonability limit, it gives off enough energy to beat the rock mass’ resistance.
