A construction method that allows for the replacement and expansion of piping branches and valves with minimal water drainage!
Outstanding breathability, high strength, and water resistance are its features! Plastic slats are actively used as a substitute for tatami flooring core materials and wooden slats.

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"!

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."
Outstanding breathability, high strength, and water resistance are its features! Plastic slats are actively used as a substitute for tatami flooring core materials and wooden slats.

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

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!

[Kyushu Area Expansion] It is now possible to carry out piping branch and valve replacement work, as well as expansion work, with minimal water drainage! Piping work can be done without shutting off water supply to the entire building.

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

Permeable sheets, waterproof sheets, and the embedding of crushed stone are unnecessary, leading to labor-saving construction, shortened processes, and improved cost-effectiveness! *NETIS registered product

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.
