Company information
Various pipelines (such as water supply, sewage, electricity, gas, and communication) that are indispensable to our lives are laid out mainly along the roads across the country, and it is said that approximately 14 million manholes have been installed for their maintenance and preservation. As urbanization progresses and sewage facilities are established, the maintenance and preservation of these systems will become crucial. To reduce maintenance and repair costs and respond quickly, the Parabola method is essential. Understanding the main features of the Parabola cutter well and implementing it as a permanent solution rather than a temporary emergency repair is believed to contribute the most to our civic life.
