Rock Breaking Tools
Hydro-Fracturing
Hydro-Fracturing uses water to create hydraulic pressure on the walls of a hole drilled in the rock or concrete to be broken.
The pressure builds until the rock or concrete breaks in a very safe and controlled manner.
Darda Hydraulic Rock and Concrete Splitters
The Darda Hydraulic Rock and Concrete Splitter is a powerful demolition tool that can generate over 800,000 pounds of breaking force on the rock or concrete to be broken. Our experienced operator can direct the direction of the break to create manageable size chunks that can be moved by hand or with heavy equipment. Click on this link for more information
Expansive Mortar Technology / Expanding Grout.
Expansive Mortar Technology also known as expanding grout is a non-explosive demolition agent used for controlled rock and concrete breaking without noise. Expanding mortar is mixed with water and poured in to pre-drilled holes drilled in a pattern to control the direction of the breaking action. This allows the user to control the size and shape of the broken chunks and exposes the rebar to be cut so the chunks can be removed and hauled away.

Propellant based technology rock breaking tools. Boulder Buster , Magnum Buster, Eze-Break Micro Blaster
The Boulder Buster and Magnum Buster are rock and concrete breaking tools that utilizes a propellant based technology. A pressure impulse is generated by a propellant cartridge. The pressure impulse is directed via a barrel in to a incompressible fluid column of water or gel placed in a pre-drilled hole in the rock or concrete to be broken. The Eze-Break Micro Blaster uses a small propellant charge that is placed in a hole drilled in the rock or concrete to be broken.
