"Rojiodoren" is a drainage pipe for landslide prevention that has good drainage properties while preventing sediment runoff and is easy to install. Recently, landslides triggered by earthquakes and heavy rainfall have been increasing. Efficient drainage of groundwater is necessary for landslide prevention. Our product has been confirmed to not discharge soil particles compared to general rigid PVC perforated pipes, based on results from a continuous 100mm rainfall experiment. [Features] - Good drainage: 45,000 fine holes per meter - No sediment runoff: Hole diameter is less than 100μ - Easy to install: Used with VP40 exterior *For more details, please refer to the PDF document or feel free to contact us.

• Other civil engineering works

The Palace Sheet consists of a jacket, filling material, and civil engineering sheet. After laying the civil engineering sheet, special mortar is filled into the jacket, which is assembled in a grid pattern, easily forming a highly rigid grid reinforcement frame. This grid reinforcement frame can distribute the loads applied to it, preventing ground subsidence (uneven settlement) and local deviations in cover pressure when heavy machinery is in operation. Since ground improvement such as cement solidification is unnecessary, the method is suitable for constructing temporary roads on leased land, as it allows for restoration simply by removing the Palace Sheet after the work is completed.

• Earthworks

The "Preload Shell Method" is a technique used in civil engineering to early suppress ground subsidence and stabilize tunnels. A bag is set between the ground and the support structure, and by filling the bag with non-shrink mortar, the support structure and the ground are integrated, demonstrating reliable support capacity. For this method, a rapid-hardening filling material called "Preload Mortar" and pressure-resistant bags have been developed, ensuring stable quality. [Features] ■ Suppresses ground subsidence during civil engineering works ■ Demonstrates reliable support capacity ■ Original rapid-hardening filling material "Preload Mortar" ■ Original pressure-resistant bag "Preload Jacket" *For more details, please refer to the PDF materials or feel free to contact us.

• Earth retaining wall/foundation reinforcement

The "SZ Pile" is a soil retention material made of H-shaped GFRP that can be cut using a shield machine. Its physical properties, such as strength and elastic modulus, are stable, allowing for safe design similar to H-shaped steel. Additionally, construction work can be handled in the same way as with H-shaped steel. Furthermore, by embedding high-strength bolts in the flange, it is possible to install a bracket plate as an option. 【Features】 ■ Integral molded H-shaped GFRP product ■ Bracket for belly support can be installed ■ Cutability ■ Environmentally friendly *For more details, please refer to the catalog or feel free to contact us.
