The "Magma Rock Method NGJ" maximizes the features of the Magma Rock Method and incorporates innovative technology to enhance the seismic resistance of the main pipe and manhole connection. Developed for the seismic reinforcement of pipe joints, the Magma Rock Method demonstrates waterproof performance that can withstand extraction due to Level 2 seismic motion. With the realization of this method, the connection between the main pipe and manhole can be improved to a seismic structure in a short time without excavation from the surface while maintaining water flow. 【Features】 - For medium and large diameter pipes, all materials can be brought in through a φ600 manhole opening, and all work can be performed inside the pipe. - The installation work for the guided joint involves cutting while leaving part of the pipe thickness, preventing the inflow of groundwater or soil during construction. - Even when the inside of the pipe is flowing, reliable construction can be completed in a short time. - The pipe diameter can be improved to a seismic structure that withstands Level 2 seismic motion, ranging from φ800 to φ3000. - The Level 2 seismic performance of Magma Rock has been verified through various waterproof tests. *For more details, please refer to the PDF document or feel free to contact us.

The "Magma Rock Method mini・NGJ" is a non-excavation seismic reinforcement method developed to enhance the seismic resistance of the "pipe connection points where existing pipelines and manholes connect," which do not have seismic resistance, targeting pipe diameters of 700mm or less. Based on the seismic technology cultivated in the "Magma Rock Method NGJ," which targets diameters of 800mm and above, this method improves the pipe connections of existing pipelines and manholes that lack seismic resistance to a seismic structure that can withstand Level 2 seismic motion. 【Features】 - All work, including the installation of guiding joints, can be performed inside the manhole, eliminating the need for work on the ground. - Reliable construction can be achieved in a short time, even when the pipe is in a flowing state. - The guiding joints are cut into the pipe while leaving part of the pipe's thickness, preventing the intrusion of groundwater or soil during construction. - Small diameter pipe connections (φ200 to φ700) are improved to a seismic structure that can withstand Level 2 (seismic motion). *For more details, please refer to the PDF document or feel free to contact us.

The "Snap Lock Method" is a non-excavation repair technique that stops inflow and leakage from existing pipe joint areas while allowing the flowing sewage to remain as is, and it also achieves seismic reinforcement. There are two methods: "Snap Lock Method S," which is a water-stopping technique that can be reliably implemented even in flowing conditions to stop inflow (leakage) from existing pipe joint areas or defective locations, and "Snap Lock Method ML," which adopts this technology. Additionally, this method thoroughly pursues durability and cost-effectiveness. [Features] ■ Excellent water-stopping capability ■ Excellent durability ■ Excellent workability ■ Easy follow-up investigation *For more details, please request materials or view the PDF data from the download section.
