The "Daiyu-style Universal Cover" is a concrete floor slab that can accommodate sizes and specifications tailored to site conditions. The product features slits on the surface in the horizontal direction, allowing for surface water collection. It prevents rattling and noise through anchoring. Additionally, it can accommodate widths up to 1000 mm and is primarily used in side ditches and waterways. 【Features】 ■ Equipped with slits ■ Allows for surface water collection ■ Accommodates widths up to 1000 mm ■ Prevents rattling and noise through anchoring ■ Accommodates sizes and specifications tailored to site conditions *For more details, please refer to the PDF document or feel free to contact us.

• Inspection hatches, manhole covers, and ditch covers

"Vegiporous" is a vegetation revetment block developed to ensure the necessary strength as a revetment block and to allow plants to take root or for root hairs to penetrate and reach the subgrade. By using heavy aggregates, it is 20% thinner than regular porous concrete products, making it easier for plant roots to enter. The iron content (ferrous ions) contained in the aggregates enhances vegetation functionality. Additionally, the surface has a rough structure, allowing for a larger vegetative area. 【Features】 ■ Easy entry for plant roots ■ Expected early restoration effect of vegetation ■ Iron content in the aggregates improves vegetation functionality ■ Obtained certification for hydraulic characteristics of revetment blocks ■ Allows for a large vegetative area *For more details, please refer to the PDF materials or feel free to contact us.

• Various blocks

The "Line Waterway Block" is a boundary block for pedestrian and vehicle paths that integrates a water channel as an alternative structure to L-shaped street gutters. By eliminating the apron, the flat surface area is expanded, improving the safety of shoulder driving. With fewer construction types and a shortened process, it reduces the burden on nearby residents (noise and vibration) and also mitigates the impact on current road traffic (congestion and the possibility of accidents). 【Features】 ■ Improved safety for shoulder driving ■ Ensured flatness, elimination of steps and grooves ■ Resolution of water pooling at intersections ■ Suppression of water splashing on pedestrians ■ Improved workability *For more details, please refer to the PDF materials or feel free to contact us.

• Paving Materials

The "Easy Slit Drain" is a freely sloped drainage channel with a slit groove on the top edge and a split design for the upper and lower parts. Unlike regular freely sloped drainage channels, this product has a bottom plate, eliminating the need for foundation concrete. Water can flow into the interior through the joint slit, and it is compatible with permeable pavement. 【Features】 ■ Upper and lower combination method ■ No foundation concrete required ■ Enhanced adhesion performance of invert concrete ■ Compatible with permeable pavement ■ No noise generated *For more details, please refer to the PDF document or feel free to contact us.

• Gutters and U-shaped gutters

"Polamess" is a high-drainage vertical retaining wall that smoothly promotes drainage from the entire wall surface while possessing the required strength. Thanks to its hybrid structure of porous concrete blocks and welded wire mesh, it allows for easy construction of economical vertical retaining walls. Additionally, when installed on sloped surfaces, it has a lower vertical height compared to block masonry retaining walls and gravity retaining walls, making it more economical. 【Features】 ■ Balanced stacking is possible with shorter counter lengths from the upper tier to the lower tier. ■ Reduces the amount of excavation and backfill compared to reinforced earth walls and L-shaped retaining walls. ■ Curved construction using standard components is easy and results in excellent shape. ■ Capable of constructing retaining walls with high connectivity and integrity. ■ Compared to on-site retaining wall construction, it helps reduce greenhouse gas emissions. *For more details, please refer to the PDF materials or feel free to contact us.

• Retaining wall

The "TB (Touch Bond) Method" is a seismic joint construction method that clears "Level 2 seismic motion" through one-touch joint connections and high-elasticity adhesives. The connection structure for curved sections, cross-sectional changes, and joints with existing structures is the same as that for straight sections. It maintains water tightness equivalent to or greater than elastic sealing (over 0.1 MPa) even after displacement. Additionally, since the product can simply be installed and injected or caulked, it allows for reduced construction time and cost savings. 【Features】 ■ Follows various ground displacements such as Level 2 seismic motion and permanent deformation ■ The connection structure for curved sections, cross-sectional changes, and joints with existing structures is the same as that for straight sections ■ Simply install the product and inject or caulk ■ Can accommodate outdoor temperatures during construction from -10°C to 40°C ■ Can be connected as a seismic joint to site-cast manholes and existing boxes *For more details, please refer to the PDF materials or feel free to contact us.

• Earthquake-resistant construction method

This technology allows for the reinforcement of aging small and medium-sized bridges while maintaining existing road traffic. It involves the installation of precast box culverts through horizontal pulling into the space beneath the girders, thereby integrating them to extend the lifespan of the existing bridge. It aligns with the Ministry of Land, Infrastructure, Transport and Tourism's initiative to improve productivity in concrete construction. It achieves extended lifespan, cost reduction, and shortened construction periods. 【Features】 ■ Reinforcement of aging bridges with precast box culverts ■ Construction can be carried out while keeping existing road traffic open (no detours required) ■ Achieves extended lifespan, cost reduction, and shortened construction periods ■ Adapts to the Ministry of Land, Infrastructure, Transport and Tourism's initiative for productivity improvement in concrete construction ■ Simplifies maintenance management *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

This product is a precast L-shaped retaining wall that is integrally molded with a foundation for installing type C or type B vehicle guardrail posts on the vertical wall section. It has been verified through full-scale collision tests for the stability and strength of the retaining wall against collision loads, as well as the vehicle guidance performance and off-road deviation prevention performance of the vehicle guardrail. It can be used as a guardrail foundation on top of reinforced earth wall methods, or it can be constructed directly on the foundation. 【Features】 ■ Construction is possible on longitudinal slopes (up to 15%) and curved sections ■ Can be used as a guardrail foundation on top of reinforced earth wall methods ■ Can also be constructed directly on the foundation ■ Confirmed to not produce harmful cracks or damage, and to have minimal impact on lower retaining wall works such as reinforced earth walls *For more details, please refer to the PDF materials or feel free to contact us.
