Nihon Kensetsu Gijutsu Co., Ltd.

We develop regional environmental preservation technologies, such as unique water filtration materials and methods.

Our company’s history began with geological investigation. We have extended our business to fields from global environment preservation to civil engineering, such as anti-landslide works. We have advanced material development to recycle waste glass materials, and developed our Miracle-Sol product and its construction method. Miracle-Sol is a water filtration material that is effective for reducing environmental burdens. This ultra-porous water filtration material is manufactured from a vitreous base material that was born from technical development of a water environment preservation method. The specific surface area (square meters/cubic meters) is as large as 78,000 to 281,000, which is about 100 to 1,000 times that of plastic filtering media. This material is capable of stably decomposing ammonia. It is more economical than other filtration materials and can be stably supplied.


Other presentation

[Company strength]
Our company has three overall advantages.
(1) High technical power: We have accumulated technologies about various environmentally friendly methods. We can provide high-safety, high-quality civil engineering structures that satisfy various customer needs while remaining friendly to the surrounding environment.
(2) Human resources and R&D power: We have four staff members with engineering doctorates and about 100 with national qualifications as professional engineers and RCCMs. Our technical laboratory develops new materials based on waste glass materials as well as civil engineering technologies that make effective use of thinned wood.
(3) Industry-university-government collaborative power: We can proactively meet social needs in collaboration with universities, national research organizations, and other companies.

[Business description]
Our company’s history began in the boring business in 1953, and we were incorporated in 1962. We have been extending our business since our establishment from geological investigation to anti-landslide, slope stabilization, slope protection, and general civil engineering works. We have been working to improve our technical power while promoting business expansion to construction-related fields, such as surveying and construction consulting. Since 1995 we have been proceeding with R&D on future materials for the purpose of recycling waste glass materials. We marketed our Miracle-Sol product as a water filtration material effective for reducing environmental burdens and marketed its construction method to contribute to preserving the global environment.

[Strength of products/technologies]
Our Miracle-Sol product is an ultra-porous water filtration material manufactured from a vitreous base material that was born from technical development of a water environment preservation method. This is a lightweight ceramic material made by sintering fine glass powder blended with a foaming agent at 900 ºC. Miracle-Sol stably decomposes ammonia because its specific surface area (square meters/cubic meters) is as large as 78,000 to 281,000. This is about 100 to 1,000 times greater than plastic filtering media. This material is more economical than other filtration materials and can be stably supplied in large volumes.

[Representative's message]
Our company is devoted to technical development and promoting effective uses of resources to protect, preserve, and create global and regional environments. We also propose the Miracle-Sol cluster method, which makes use of a material that we developed through our activities. We will continue to develop and invent methods for water environment preservation, environmental greening, and environmental civil engineering. We will also create new future materials with the motivation and aspiration to take on new challenges while setting our sights on the next stage.

[Company structure for market development/overseas expansion]
Our technical laboratory responds to technical inquiries. Our construction material sales department and construction business department are in charge of sales negotiations. The Kanto branch handles inquiries in the Kanto region. Direct transactions with overseas customers are under consideration.
