HYDRAULIC DRILL METHOD

      • HYDRAULIC DRILL METHOD

      Traditional Japanese demolition technology uses hydraulic power. Since this method does not entail blasting, it generates minimal noise and vibration, and is ideal for sites that have environmental constrictions. Compared to the traditional blasting approach, it is possible to control the direction of splitting; moreover, work can be done accurately without flying objects.
