The "Miedoren G Series" is a water conduit made of a one-piece structure using flame-retardant materials. It excels in weather resistance and impact resistance, and due to its one-piece structure, there is no water leakage from the conduit body, ensuring reliable water management. Bending, joint processing, and welding can be easily performed according to the leakage situation. The SK seal, being an independent foamed product with an extremely low water absorption rate, prevents water seepage and absorbs irregularities in the wall surface, thus preventing leaks. 【Adopted Construction】 Tunnel repair work Cave repair work Culvert repair work Underground passage repair work Road repair work Other various repair works 【Features】 ■ Due to its certain flexibility, it can be installed in narrow arch areas such as single-line tunnels. ■ As it is a one-piece structure, there is no water leakage from the conduit body, ensuring reliable water management. ■ The SK seal, being an independent foamed product with an extremely low water absorption rate, prevents water seepage. ■ Bending, joint processing, and welding can be easily performed according to the leakage situation. ■ The installation of the conduit is extremely easy, allowing for quick construction. *For more details, please refer to the PDF document or feel free to contact us.

【Adopted Construction】 Tunnel Repair Work Tunnel Maintenance Work Culvert Repair Work Underpass Repair Work Road Repair Work Other Various Repair Works 【Features】 ■ No water leakage from the gutter body, and it can be securely fixed to the wall surface. ■ Anchors fit inside the gutter, allowing installation even in pedestrian walkways and areas with strict construction limits. ■ Suitable for locations exposed to wind pressure and areas with poor wall quality. ■ Gutter installation work is extremely easy, allowing for quick construction. ■ SK seal prevents water seepage and absorbs wall irregularities to prevent leaks. *For more details, please refer to the PDF materials or feel free to contact us.

The "Miedoren H Series" is a drainage channel made of flame-retardant materials that can reliably direct water leakage from the wall side horizontally. Since the joint areas can be covered, it looks good and prevents clogging from external factors such as dust. The drainage plate (UL certified) can be removed, making inspection and cleaning easy even if there is clogging due to free lime or other materials. 【Adopted Construction】 Tunnel repair work Tunnel maintenance work Culvert repair work Underground passage repair work Road repair work Other various repair works 【Features】 ■ Effectively directs water leakage from the wall side joints horizontally ■ Covers joint areas to prevent external clogging ■ Easy inspection and cleaning even if clogging occurs ■ Using the drainage plate allows for easy confirmation of the internal condition of the channel from the outside *For more details, please refer to the PDF document or feel free to contact us.

【Adopted Construction】 Tunnel Repair Work Tunnel Rehabilitation Work Culvert Repair Work Underpass Repair Work Road Repair Work Other Various Repair Works 【Features】 ■ Broadly covers leak points, enabling reliable surface drainage treatment ■ Suitable for areas subject to high wind pressure as FS boards and tie boards (UL certified) are securely anchored together ■ Multi-row construction surface drainage channels are suitable for preventing peeling and falling due to aging deterioration of tunnel inner walls ■ SK seal prevents water seepage, absorbs irregularities in the wall surface, and prevents water leakage *For more details, please refer to the PDF materials or feel free to contact us.

The "Miedoren MJ Series" is a water diversion channel made of non-combustible materials that widely covers leak points and accurately facilitates water diversion treatment. It uses panels certified as non-combustible materials by the Ministry of Land, Infrastructure, Transport and Tourism.

We would like to introduce a case study of the installation of the water guide pipe "EF-385 Standard Transparent Type" for the repair of tunnels in Fukui Prefecture. In this tunnel, water leakage occurred from the joints and cracks in the lining surface due to aging. Particularly in winter, freezing could lead to slip accidents, and because there were numerous leakage points, other construction types faced the possibility of prolonged work. With this product, water leakage can be directed to the drainage channel without adversely affecting passing vehicles or pedestrians. 【Case Overview】 ■ Issues - Water leakage occurred from the joints and cracks in the tunnel lining due to aging. - Water that leaked onto the road could freeze in winter, leading to slip accidents. - Due to the numerous leakage points, other construction types (such as crack injection) faced the possibility of prolonged work. ■ Reasons for Adoption - Compared to other construction types, it can be installed in a short period. - It can serve both as a water leakage countermeasure and a peeling prevention measure, making it economical. - Since it can be processed on-site, it can be installed without removing or relocating existing structures. - By adopting the transparent type, visual inspections can be conducted after installation. *For more details, please refer to the PDF document or feel free to contact us.

The "Findlevin" underground drainage pipe (bundle pipe) is a high-performance underground drainage pipe that forms numerous linear water collection points and drainage channel spaces. It demonstrates high drainage effectiveness, especially in poorly draining ground and slopes. 【Features】 ■ Excellent pressure resistance due to the bundling of high-performance S-type drains. ■ Numerous continuous linear water collection points and linear drainage channel spaces are formed, providing high collection and drainage capacity. ■ Water flows smoothly through many slits, making it resistant to clogging and effective for long periods. ■ High pressure resistance allows for shallow burial depth, making it economical. *For more details, please download the PDF or feel free to contact us.

■Features - Excellent drainage effect on slopes, demonstrating strong erosion prevention. - The retaining wall and anchor piles work together to support soil pressure at each level. - Additionally, the drainage and retaining effect integrates the entire slope, preventing slope failure. - Internal drainage within the slope provides a stable surface, offering a soil stabilization effect. - As it is a method of underground installation, it allows for natural scenery through greening. - Does not use lead-based stabilizers, considering environmental impact.
