While there are several methods for addressing water in an underground environment, such as common dewatering and grouting, these exercises do not offer complete relief from the issues arising from water inside the holes. With all explosives, including “water-resistant” emulsions susceptible to degradation (be it at varying degrees), there is both a performance issue to manage as well as a containment issue caused by explosive seepage and slumping when too much water is present.

To adequately address both, protecting explosives during the loading process is critically important to achieving a good blast outcome.
