A construction method that allows for the replacement and expansion of piping branches and valves with minimal water drainage!

Smooth renovation of facilities for the entire apartment complex! No need for temporary evacuation for first-floor residents, with a significant reduction in noise and dust due to the new construction method.

A construction method that allows for pipe branching, valve replacement, and expansion work with minimal water drainage! We have newly started a warranty system for the "freezing method"!
Developed a siphon drainage system that allows for zero fuel costs and can be manually transported to prevent water level decline and dam failure! Drainage using the principle of siphoning can be easily activated!

Piping and wiring burial system (non-excavation and thrust method)! Numerous achievements! Attention on "overhead wire elimination"! "Challenging the creation of lifelines that traverse the earth and underground."

The basic principle is to combine it with other construction methods! The effectiveness of the combined construction methods increases, leading to a reduction in construction time.

When freezing methods cannot be used! Mechanically stop water at any location!

Effectively eliminate groundwater that induces landslides - Large-diameter drainage horizontal hole method.

Insert into the slope to drain groundwater and contribute to preventing slope collapse【NETIS registration number KT-120016-VE】.

We obtained "water-absorbing paper" with a water absorption capacity of more than four times its own weight by using wood pulp, a forest resource, as the raw material and enhancing the swelling properties of the pulp fibers themselves!

Utilize limited water resources efficiently without waste! Just by installing it, you can save water and reduce costs.

Dredging and cleaning can be performed according to the site conditions! Remote operation allows for compact, efficient, and safe work even in areas where conventional dredging was difficult.
