Freezing Method "ICELOCK"

No generation of industrial waste without contaminating soil or groundwater! Introducing environmentally friendly construction methods.

"ICELOCK" is a ground improvement method that involves burying freezing pipes underground and freezing the surrounding soil to create a solid frozen ground. Frozen ground can exhibit high ground strength and excellent water impermeability, making it suitable for civil engineering projects, especially in deep depths and under high groundwater pressure. Since no materials are added to the ground to strengthen it, the environmental impact is minimal, and it is considerate of nature. 【Features】 ■ Environmentally friendly ■ High strength ■ Applicable to all soil types ■ Good adhesion with other materials ■ High water impermeability ■ Flexible setting of construction targets *For more details, please refer to the PDF materials or feel free to contact us.

Piping construction "Freezing method (building)" continuous water freezing method 'DOWS method'

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.

The "DOWS method" is a technique used to assist "freezing methods" and "DSP methods" by temporarily stopping the flow of water (temporary water stopping). This method is not used alone; it is fundamentally combined with other methods. By adopting the "DOWS method," it is possible to avoid complete water stoppage, enhance the effectiveness of the combined methods, and shorten construction time. 【Features】 ■ Freezing is possible without operating existing valves ■ No concerns about damage, leaks, or discolored water due to valve operation ■ When freezing methods are applied at both ends, the area of water stoppage can be minimized ■ Installed at the section of pipe removal, leaving no saddle after construction ■ If the valve does not work and does not freeze with the "freezing method," it is also possible to apply the "DOWS method" later *For more details, please refer to the PDF document or feel free to contact us.

Piping construction "Freezing method (building)" continuous water freezing method 'DSP method'

It is possible to carry out the "closure work on the T-shaped pipe for two receivers" without shutting off the main pipe!

The "DSP Method" is a technique used for branching pipes in T-shaped pipes, split T-shaped pipes, and welded piping, where it is difficult to apply freezing methods. When using freezing methods for branching sections, there are conditions and limitations, but with the "DSP Method," valve replacement and shut-off work can be done safely and without worry. 【Features】 ■ Allows construction related to branching sections of piping that are difficult with freezing methods. ■ Enables smooth construction related to branching sections from large-diameter pipes, which was previously challenging. *For more details, please refer to the PDF document or feel free to contact us.

Piping work and water pipe repair "Freezing method: Continuous water freezing method" New warranty system

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"!

The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water inside pipes, allowing for branch pipe work, valve replacement, and expansion work with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off the water supply to the entire building. To ensure that you can use the "freezing method" with even greater peace of mind, we have introduced a new "guarantee system." There are no cumbersome procedures or additional costs; it will apply simply by placing your order as usual. *For more details, please refer to the PDF document or feel free to contact us.*
