Flexible cantilever retaining wall "Free Wall (Box-type Retaining Wall)"
Retaining wall constructed with precast products and single-sized crushed stone.
■NETIS CB-040038-A (Publication period ended) ■This is a retaining wall that obtained construction technology examination certification from the Public Interest Incorporated Foundation Civil Engineering Research Center in March 2004. ■Due to its flexible structure, it reduces the stress generated by the slight movement of the retaining wall against soil pressure during an earthquake, thereby suppressing cracking and collapse of the wall. ■The ground reaction force during an earthquake is relatively small, and it demonstrates adaptability to differential settlement of the foundation ground and backfill soil, maintaining the overall safety of the retaining wall. ■The layer of single-sized crushed stone has extremely high drainage capacity, which inevitably stabilizes the backfill soil. ■Since there is almost no work involving rebar, concrete, or formwork at the construction site, significant reductions in construction time and improvements in cost-effectiveness can be achieved. ■The product can be used in a reversed manner, making it easy to construct curves. ■The stepped shape has a three-dimensional aesthetic appeal, and it is possible to consider ecosystem preservation through planting and natural greening using each small step. ■The maximum wall height in construction achievements is 21m. (Please consult us regarding applicable heights) *For more details, please download the materials or contact us through our company website.*

Road Plus
A cantilever road widening method that allows for a maximum road widening of 1.75 meters to be constructed in a short period by installing it on existing roads.
■Reduction of environmental impact on the mountain and valley sides - Due to the cantilever structure, excavation of the mountain side is unnecessary, which minimizes the impact on the valley side, such as rivers and waterways. ■Early traffic opening - By using precast products, temporary construction can be reduced, leading to a shorter construction period. ■Cost reduction possible - By removing part of the existing retaining wall's top and installing blocks, reconstruction of the retaining wall is unnecessary, resulting in cost savings. ■Compatibility with vehicle protective fences - It is compatible with vehicle protective fences (Type B and Type C), and the installation span for P-type support allows for compatibility with both vehicle and sidewalk protective fences. ■Road widening according to regional characteristics - Depending on regional characteristics, it can accommodate specifications for either large vehicles or medium vehicles.

Precast Saya Pipe Block
Suppressing the impact of bridge pier vibrations during an earthquake! It is possible to absorb the relative displacement between the bridge pier and the embankment, thereby mitigating the impact on the embankment.
The "Precast Saya Pipe Block" is a method for strengthening embankments that is installed around bridge piers to prevent the transmission of vibrations from the piers during an earthquake. Products in circular or rectangular shapes are used vertically according to the shape of the bridge pier, creating a gap around the pier. This absorbs the relative displacement between the pier and the embankment, mitigating the impact on the embankment. 【Construction Steps】(Procedure for each layer) (1) Delivery of materials (2) Assembly of U-shaped components (R components) (3) Joint treatment of components (4) Assembly of rectangular components (5) Pulling the product closer (6) Injection of upper and lower mortar (7) Installation of rubber plates (8) Completion of one layer

Exterior Block "Sun Shadow"
A uniquely angled slit transforms light and shadow into design! Introducing the exterior block.
"Sunshadow" is a revolutionary material that can incorporate light and shadow into spatial design. The slits running across the surface are carved in such a way that the slope reverses at the center of the block, creating a characteristic appearance where brightness and darkness differ between the foreground and background, or from left to right. It can appear as a single color or as if two colors are used, and can create rhythmic patterns, with a rich variety of colors and options for permeable, water-retaining, and non-permeable surfaces, making it widely usable. [Features] - Shadows that change depending on the viewer's position - High workability with symmetrically angled slits - The contrast of shadows is most pronounced at about 2.5 meters away - Comfortable for strollers and wheelchairs *For more details, please refer to the PDF document or feel free to contact us.
