Rock Fracturing Capabilities
Sometimes controlled blasting isn’t an option because of the vibration, risk of fly rock, noise, or sensitive facilities nearby. In these cases, in lieu of a blast, we fracture the rock or concrete with chemical rock-splitting agents and hydraulic breakers. Regardless of your needs, we’ll find the right solution to keep your project progressing forward.
- Excavator-Mounted Hydraulic Breakers for fracturing large areas of rock or concrete
- Dā-mite® Rock Splitting Mortar for silent, vibration-free fracturing in rock-cuts up to 50 feet deep
Palmetto Rock was contracted by an Upstate South Carolina utility contractor to fracture trench rock for the installation of a new waterline at a local medical facility’s campus expansion project.
The close proximity to existing natural gas, water, and sanitary sewer utilities prohibited the use of explosives for blasting of the rock. Instead, our team developed a project-specific drill pattern with 2.25” pre-split holes spaced on 14” centers on each side of the trenches, as well as an internal diamond pattern of 2.50” holes on 18” centers.
Non-explosive rock breaking mortar was then mixed and placed in the holes which ultimately resulted in the successful fracturing of the rock. This fracturing allowed for the trench rock excavation necessary to install the new water lines.
