"Rock-Lock" is a non-explosive demolition agent that provides effective crushing in environments with constraints such as vibrations in civil engineering and demolition work. It is adopted in sites where reliable crushing of target materials is necessary, such as areas where mechanical excavation of bedrock or concrete is not possible, or where vibration suppression is desired compared to explosives, contributing to labor-saving in removal work and shortening construction periods. Being non-explosive, it does not require permits or ancillary equipment like explosives do. 【Features】 - No permits or ancillary equipment required due to being non-explosive - Enables low-vibration and environmentally friendly crushing - Ensures reliable crushing even in hard rock conditions - Proposes effective crushing using staged ignition devices *We have introduced examples of crushing in deep foundation work with photos in a PDF document. *For more details, please download the PDF or feel free to contact us.

"Rock Rack®" is a non-explosive breaking agent developed to efficiently crush targets near security properties, using the expansion pressure from a thermite reaction to break rock formations and concrete structures. It consists of a cartridge containing the breaking agent and two types of igniters (instantaneous and sequential). The instantaneous igniter uses a detonator, while the sequential igniter uses a dedicated ignition device. 【Features】 ■ As it is non-explosive, it is not subject to the Explosives Control Law, making handling related to storage and consumption permits simpler. ■ It can perform low-vibration breaking compared to explosives, as it breaks rock and concrete using expansion pressure. ■ By using a sequential igniter with appropriate time intervals, the impact on the surroundings can be minimized. ■ The use of electronically controlled sequential igniters improves breaking effectiveness in tunnels and deep foundations. ■ Although it is not subject to the Explosives Control Law, the work procedures are similar to those of blasting methods. *For more details, please request materials or view the PDF data available for download.
