"Di-Lock" is a large, self-supporting block with a 350 mm setback designed for dry stacking. Each block covers 1 m² and can be installed horizontally to achieve a 5-degree slope, making construction easy. The surface features a split stone pattern that takes landscape considerations into account, and it has obtained brightness certification and texture certification. 【Features】 ■ Self-supporting with a 350 mm setback ■ Top concrete (t=10 cm) can be installed within the block ■ Can accommodate backfill concrete (t=100–150 mm) ■ Brightness certification: Satisfies a brightness of 6.0 or lower (All Japan Association Certification No. 1360) ■ Texture certification: The standard deviation of brightness (average) is 11 or higher (All Japan Association Texture Certification No. 0175) *For more details, please refer to the PDF materials or feel free to contact us.

The "SR Form" is an embedded form block that can be used as a formwork for cast-in-place concrete for sloped coastal levees. By using this product, construction time can be shortened and labor can be reduced. The surface of the block features a rough sand pattern to ensure safety in maintenance management and coastal use, as well as to consider the landscape. Additionally, the product thickness is 500mm, satisfying the 500mm requirement of the "Technical Standards for Coastal Conservation Facilities." 【Features】 ■ The block surface has a rough sand pattern ■ Meets the 500mm requirement of the technical standards for coastal conservation facilities ■ Factory-produced, ensuring stable quality ■ Significantly reduces formwork for cast-in-place concrete ■ Reduces industrial waste and considers the environment *For more details, please refer to the PDF materials or feel free to contact us.

The "Test Band Method" is an air-based water tightness inspection method for pipeline joints that does not use water. By using air as the pressurized fluid, the testing equipment is simplified and lightweight, improving work efficiency, reducing costs, and shortening construction time, while also allowing testing in inclined pipelines. All necessary materials can be brought in and out through a manhole with a diameter of 600mm, and assembly and disassembly within the pipe can be easily performed. 【Features】 ■ Uses air as the pressurized fluid ■ Simplified and lightweight testing equipment ■ Easy assembly and disassembly within the pipe ■ Testing possible with flexible and rigid pipes ■ Patent No. 4978905 *For more details, please refer to the PDF materials or feel free to contact us.

• Hydrological survey

The "Water Stop Band Method" is a repair technique that uses water-expandable sponge within the water-tight rubber of the water stop section to prevent the decline in water stop performance caused by the compression permanent deformation of the water-tight rubber. The water-expandable sponge attached to the water stop section of the water-tight rubber enhances the water stop effect due to the lateral restraint force at both ends of the attachment groove. Additionally, by making the bolt fixing part after the expansion of the fixed ring in a wedge shape, it creates a structure that prevents loosening. 【Features】 ■ Repair and seismic reinforcement method for pipeline joints ■ Prevents decline in water stop performance ■ Uses water-expandable sponge ■ Loosening prevention structure ■ Design registration No. 1400834 *For more details, please refer to the PDF document or feel free to contact us.

Green Porous is a large revetment block that incorporates a natural stone pattern. It features continuous voids characteristic of porous concrete, making it an environmental block that combines permeability, planting functionality, and flood control capabilities. When blocks made of porous concrete with a continuous void ratio of 18% to 25% are used for riverbank revetments, water, air, and soil can enter the continuous voids, connecting the block surface with the ground. Furthermore, the continuous voids purify water and allow it to permeate underground, as well as cleanse the interstitial spaces. When plants grow and insects or small animals are present, fish are attracted to the water's edge. This helps preserve rich nature and creates robust levees. 【Features】 - Large revetment block incorporating a natural stone pattern - Formed from porous concrete - Possesses continuous voids, permeability, planting functionality, and flood control capabilities - Maintains sufficient strength and durability as a revetment structure - Planting holes in the recessed gaps and joint areas allow for vegetation For more details, please contact us or download the catalog.
