The cause of poor drainage is due to blockages in the underground drainage pipes and root obstructions. In particular, common drainage pipes are prone to clogging from gravel, tree roots, and debris, and when there are blockages or root obstructions in buried pipes, it becomes difficult to address them, leading to the hassle of replacement. Mitsuba Drain is a drainage pipe with slotted inlets that has excellent water collection capabilities. The direction of drainage aligns with the direction of the inlets, allowing water to flow in smoothly with outstanding collection ability. It is effective for ground, parks, construction site drainage works, and other groundwater measures. 【Features】 ■ Outstanding water collection capability ■ Good drainage and durability ■ No movement of fine soil ■ High resistance to water scale adhesion ■ Sufficient pressure resistance *For details on the mechanism and construction examples, please download the PDF.

"Rec Drain" is a hard PVC gutter that is fire-resistant, weather-resistant, and impact-resistant, designed to collect and drain water leaking from concrete structures and joints. It features easy installation with mechanical fixation using bolts and nuts, and can be shaped according to the specific needs of the site. Additionally, the product can be designed with a drainage slope, allowing for smooth drainage. [Features] - Fire-resistant, weather-resistant, and impact-resistant - Mechanically fixed with bolts and nuts - Can be shaped according to application - Capable of having a drainage slope *For more details, please refer to the catalog or feel free to contact us.

The "Slope Drain" is a synthetic resin slope protection structure that prevents erosion and collapse of slopes through internal water drainage and retaining effects. In addition to the soil retention effects of traditional fencing and woven fencing, it can also handle infiltrating water and spring water within the slope. The drainage effect of the buried pipe is expected to enhance the internal friction and cohesion of the soil, ensuring resistance to sliding. The filter net is inclined at approximately 10° to the vertical, and the water drainage at the bottom of the net significantly improves water collection efficiency. 【Features】 ■ Double effect of soil retention and buried drainage ■ Improvement of embankment and soil quality ■ Effect of stabilizing embankments ■ Increased water collection efficiency ■ Design adaptable to various situations *For more details, please refer to the catalog or feel free to contact us.

The "Side Drain" is ideal for preventing water leakage from horizontal directions such as spring lines. Sub-rails and size adjustments can be made as needed, allowing for construction that meets site requirements. Additionally, by using a raising plate, water treatment on the wall surface above the tunnel can be performed. 【Features】 ■ Optimal for preventing water leakage from horizontal directions ■ Sub-rail installation is possible ■ Size adjustments are possible ■ Design and manufacturing of various shaped gutters and catch basins are possible ■ NETIS registered (KK150047-VE) *For more details, please refer to the catalog or feel free to contact us.

• Roof and gutter construction

The 'Elasto Drain' has adopted flexible materials for its drainage pipes used in leak prevention measures, enabling protection against damage to the pipes from vibrations such as earthquakes and allowing installation at uneven surfaces. It can be used for leak prevention from joints and cracks in concrete structures, as well as for water stopping in central medians and preventing concrete spalling. [Features] - Weather resistance - Flame retardancy - Flexible material *For more details, please refer to the catalog or feel free to contact us.

• Tunnel Materials

"Arch Roofing" is a waterproof, impact-resistant, and fire-resistant aluminum laminated composite material that can handle any leakage.

The "Arch Drain Line Water Guide" is a flame-retardant and impact-resistant plastic channel designed to quickly manage water leakage from construction joints, cracks in concrete walls, and other areas in tunnels, underground structures, and buildings. With a wide variety of types (various water guide widths, shapes, etc.), it can handle any type of leakage. The water guide plate and the corners on both sides are at right angles, preventing any bending of the plate or blockage of the water guide cross-section. Due to the large cross-sectional coefficient of the corners, the water-stopping material is evenly pressurized, ensuring reliable water stopping. 【Features】 ■ Reliable water stopping ■ Strong and lightweight ■ Flame-resistant ■ Resistant to natural environments ■ Excellent workability ■ NETIS registered (KK-120043-VE) *For more details, please refer to the catalog or feel free to contact us.
