The "Next Generation Underground Utility Duct" is a facility designed to accommodate power lines, fiber optics, and other electrical cables when they are buried underground. Our company is promoting a system for undergrounding electrical cables using precast utility ducts, aiming for beautiful streetscapes and disaster-resistant urban development. With the removal of utility poles, road improvements are also made, allowing for wider sidewalks. This not only enhances visibility at intersections but also creates a comfortable barrier-free environment where pedestrians, strollers, and wheelchairs can pass safely. 【Features】 ■ Easier passage for both people and vehicles ■ Cleaner and more beautiful streetscapes ■ Creating disaster-resistant communities ■ Improving the safety and reliability of information networks *For more details, please refer to the PDF document or feel free to contact us.

"All Weather" is a box drain designed with an increased number of side drainage holes to accommodate permeable pavement, allowing for more uniform and efficient drainage. The position of the side drainage holes can be adjusted to accommodate various pavement thicknesses. To ensure smooth water flow during low water levels, the bottom of the pipe channel is shaped in an R-type, which minimizes sediment accumulation even during prolonged good weather. Additionally, we offer options such as the "All Weather Non-Slip Type," which places greater emphasis on slip resistance, and the "All Weather Bicycle Path Compatible EJ." 【Features】 ■ Allows for more uniform and efficient drainage ■ The position of the side drainage holes can accommodate various pavement thicknesses ■ Excellent at collecting water runoff, minimizing water accumulation in the entry area ■ Reduces sediment accumulation even during prolonged good weather ■ Can be used as a bicycle path compatible type with an apron width of 80mm and an apron slope of 2% *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our DCJ box culverts, "K type/T type." The "K type (flexible joint box culvert)" has flexibility in each product, ensuring sufficient water-tight performance. When ground conditions are good, it exhibits seismic performance due to the small amount of extraction and bending angle caused by seismic motion. The "T type (seismic-resistant joint box culvert)" addresses permanent deformation of liquefied ground due to lateral flow and permanent deformation of sloped ground in artificially modified areas by increasing the insertion length of the joint, satisfying the necessary extraction amount while ensuring sufficient water-tight performance. 【Features】 ■ Available in two types: "K type" and "T type," allowing for selection based on application ■ Capable of minimizing the extraction amount and bending angle occurring at each joint ■ Excellent followability, compressive recovery, and abrasion resistance ■ Maintains high water-tight performance (0.06MPa) even during extraction due to seismic motion or after bending *For more details, please refer to the PDF document or feel free to contact us.

The "Flexible Cap Comb Block" is a precast concrete product that can flexibly respond to on-site demands. In addition to steel sheet piles (standard, wide, and hat-shaped), it also offers a lineup that accommodates concrete sheet piles, making it suitable for a wide range of applications. By increasing the size of the products and simplifying the construction process, continuous construction can be achieved without delays, thereby reducing total costs. Additionally, we offer "reinforced concrete sheet piles" that have high impact resistance. 【Features of the Flexible Cap Comb Block】 ■ A product lineup that accommodates a variety of sheet pile types ■ Significant improvement in constructability ■ Reduction in total costs *For more details, please refer to the PDF materials or feel free to contact us.

The "KL Wall Type 3" is an L-shaped retaining wall certified by the Minister of Land, Infrastructure, Transport and Tourism, which can be installed where fence installation is needed and where considerations for fall prevention are necessary. Since the front wall is vertical, it allows for effective use of land up to the property boundary. With a rational design, it has a simple structure that offers good workability and excellent cost-effectiveness. Additionally, we also offer lightweight type retaining walls such as "T-LL Wall" and "ALW II." 【Features】 ■ Effective use of residential land area ■ Economical cross-section design ■ Shortened construction period and labor-saving ■ L-shaped retaining wall as a landscape material ■ Consideration for safety *For more details, please refer to the PDF materials or feel free to contact us.
