Earth-based slag pavement that solves the weaknesses of earth-based pavement.
By using blast furnace crushed slag as the main aggregate, we have eliminated the peeling and flaking that were seen in the initial stages of conventional earth pavements. The durability is also excellent due to the slag's "latent hydraulicity" (a characteristic where strength increases over time due to hydration reactions). It has a natural color and texture similar to soil, without the artificial impression often seen in asphalt or resin-based materials. It also excels in functions such as permeability, water retention, and slip resistance. 【Features】 ■ Main composition of blast furnace crushed slag mixed with sandy soil ■ Resistant to water overflow on the surface, accommodating heavy rainfall of 30mm/h ■ Mitigates the heat island effect through evaporation from the surface ■ Provides moisture to trees and flowers through evaporation, promoting growth ■ Universal design that is easy for anyone to walk on ■ Extended lifespan compared to conventional paving materials ■ Reduces the extraction of natural materials by using artificial aggregates (recycled materials) *For more details, please refer to the PDF document or feel free to contact us.
The characteristics of blast furnace slag provide long-lasting weed control! A rich variety of colors harmonizes with the landscape!
"Glassless Sand" is a weed control method that involves spreading a pavement material made by mixing blast furnace water-quenched slag as aggregate with cement and admixtures within a formwork, and then compacting it to a specified thickness. By utilizing the latent hydraulic properties of blast furnace slag, it can sustain weed control effects in a long-term and stable manner, ensuring a good landscape and visibility, as well as preventing the occurrence of pests, thereby maintaining a comfortable living environment. Additionally, by allowing rainwater to permeate through the surface of the weed control work and return to the ground, it contributes to the prevention of global warming and the reduction of environmental impact. [Features] ■ Contributes to the sanitary environment for residents living in the area through weed control work ■ Environmentally oriented with a rich variety of color options, considering landscape aesthetics ■ Contributes to the prevention of global warming and the reduction of environmental impact *For more details, please refer to the PDF materials or feel free to contact us.

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!
This document explains the reasons why "permeable and water-retaining pavement materials (color sand)" are strong against "freeze-thaw" cycles. Color sand is a pedestrian pavement material that possesses permeable and water-retaining functions while being sufficiently resistant to the repeated effects of freeze-thaw cycles during winter, making it "strong against frost damage." Among our pavement composition, the "filter layer" made from high furnace slag pavement, when used alone, has a significant effect in suppressing "frost heave phenomena." Furthermore, in freeze-thaw tests conducted at the Central Testing Laboratory of the Building Materials Testing Center, no cracking or destruction occurred even after completing 200 cycles. 【Excellent Features of the Aggregate (High Furnace Slag)】 ■ Porous Structure - Numerous fine voids release pressure caused by volume expansion during freezing. ■ Potential Hydraulic Properties - The main components of water-cooled slag (silica, alumina, lime, magnesia) solidify over time due to repeated water penetration. ◎ Sufficiently resistant to the repeated effects of freeze-thaw cycles. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.
Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!
We will explain the technical basis of the "Permeable and Water-retaining Blast Furnace Slag Pavement (Color Sand)" that achieves both permeability and water retention. All of our paving materials use "water-quenched blast furnace slag" as the main aggregate. The aggregate itself has a fine porous structure, allowing it to provide both permeability and water retention. While typical permeable paving materials allow water to pass through at "points," our paving materials enable permeability across "surfaces" due to the nature of the aggregate itself, resulting in less clogging and maintaining permeability performance over a long period. Additionally, by cleaning with high-pressure washers, the permeability can be restored to about 80%. Further explanations regarding "permeability performance" and "water retention performance" can be found through external links. 【Introduction to Technical Information】 ■ Reasons for achieving both permeability and water retention ■ Permeability performance ■ Water retention performance ■ Our product lineup *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

Support beams were also installed! We were able to keep the vibration level below 50dB!
In Tokyo, residential buildings are located close to railways that run underground, raising concerns about the impact of railway vibrations on the living environment after the construction of new homes. To address this, the 'WIB method' was implemented directly beneath the residences. Since building support was necessary, support piles were also installed. After conducting vibration measurements before and after the implementation of the countermeasures, vibrations were reduced by 12 to 17 dB (from 1/7 to 1/4), successfully keeping the vibration level below 50 dB. 【Case Summary】 ■ Location: Tokyo ■ Client: Business owner ■ Vibration source: Railway vibrations ■ Preservation target: Residential buildings along the railway (underground) ■ Countermeasure method: Plate-type WIB (honeycomb cell type) ■ Installation position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.
