CRACKAMITE is a Non-Explosive Silent Cracking/Demolition Agent
which works by providing silent expansive cracking.

Most effective solution for Rock Breaking, Stone Quarrying,
Mining, Concreate Demolition, Excavations and More...

Benefits of using Crackamite

Crackamite can be used in an almost unlimited range of applications. It’s particularly used for breaking, cutting or demolishing stones, concrete and reinforced concrete. Endless benefits of Crackamite can be listed against explosives and other methods of breaking, cutting or demolishing.

I. CRACKAMITE IS A SAFE SUBSTANCE

Crackamite is not controlled by any legal regulation such as explosives and explosive agents, etc. It is non-explosive, therefore supervision of trained personnel is not essential. Crackamite requires no special precautions if kept in a dry place. The product is not sensitive to electrical discharge or currents. Demolition can be easily and safely performed anywhere.

II. CRACKAMITE IS A SOUNDLESS CRACKING AGENT

Unlike the existing methods of demolition by explosives or breaking equipment, Crackamite does not make any noise, vibration, flying debris, dust or gas. Crackamite quietly and gradually demolishes rock or concrete with its expansive stress caused by hydration reaction. Rocks and reinforced concrete may be demolished safely without environmental pollution. Furthermore, Crackamite's expansive stress continues even after crack initiation, the crack opening distance becomes wider as time passes.

III. CRACKAMITE HANDLES EASILY

No lid (or cap) is necessary after Crackamite is poured into a hole of rock or reinforced concrete, nor is tamping required as with explosives. Crackamite exerts its strength in a short time. Due to Crackamite's strong adhesion and frictional resistance to inner surface of the hole, spurs due to heat-generation (blown-out shot) do not occur when used within the parameters as noted in the conditions. The expansive stress along the hole depth is almost constant except for that near the entrance of the hole. Generally the expansive stress loss from the hole entrance has little effect on the demolition work when hole depth is long.

IV. CRACKAMITE IS EASY TO USE - JUST Mix It, Fill It, Crack It

Just mix with water, pour into holes, then it expands to crack. Neither capping with mortar, sand, etc. nor tamping with a bar is necessary after Crackamite mixed with water is poured into drilled holes in rock or concrete. Using Crackamite does not require a special license unlike explosives, explosive agents, etc. It is environmentally friendly. It releases no toxic or harmful substances of any kind.

V. CRACKAMITE HAS AN EXPANSIVE STRESS MORE THAN 11 Mt/m2

Generally, the compressive fracture stress of rocks is 500 to 2500 T/m2 and that of concrete 300 to 500 T/m2. However, the tensile fracture stress is very small, i.e., it ranges from 40 to 70 T/m2 in concrete, respectively. Since demolition by using Crackamite is based on a fracture due to a tensile stress, all kinds of rocks and concrete can be cracked and broken by using Crackamite when appropriate holes are properly drilled.

VI. CRACKAMITE DOES SYSTEMATICAL HIGH-EFFICIENCY DEMOLITION WORK

Crackamite makes it very easy to control the shape of to-be-cracked objects after being broken according to requirements; it can be demolished or can remain unharmed. Crackamite cracks reinforced concrete, rock, limestone, granite and marble safely and quietly. Being a non-explosive material, it works without noise, vibration, dust, toxic gases and flying rock. Cracked rock or concrete can then easily be broken with breakers remarkably reducing time and cost required for breaking. Crackamite can demolish rock or concrete systematically, and also demolition work in water is possible.

Crackamite provides the most technically suitable and cost-effective solution in:

  • Restricted demolition of stone and concrete structures where nearby structures must be protected from vibration generated by explosions
  • Pre-splitting of stone formations, to create isolated blocks that can then be more easily demolished
  • Cutting blocks of marble and granite more economically than that of the traditional wire saw method
  • Excavations and demolition of stone or concrete structures where the use of explosives would be expensive due to long operating times, special transport, storage, handling precautions and the need to comply with public safety regulations.
