The  Bio Hori Drain by  DAEHAN i.m.  is an innovative  biodegradable horizontal drain  (PHD) designed to accelerate soil consolidation in soft ground while protecting the environment. Developed using biodegradable materials, the Bio Hori Drain provides an eco-friendly alternative to traditional synthetic horizontal drainage systems commonly used in land reclamation, embankment construction, and infrastructure development. This next-generation prefabricated horizontal drain offers exceptional drainage efficiency, structural reliability, and environmental sustainability, making it ideal for modern ground improvement projects that demand both performance and eco-consciousness.   Manufactured from advanced biodegradable polymers such as PBS and PLA, the Bio Hori Drain naturally decomposes over time, reducing the environmental footprint associated with long-term synthetic waste. Despite its biodegradable nature, the drain is engineered to retain high mechanical ...

The  DAEHAN i.m.   biodegradable wick drain  represents the next generation of prefabricated vertical drains (PVDs) — designed to enhance soil consolidation while protecting the environment. Developed with biodegradable materials, this innovative wick drain solution helps accelerate the drainage of pore water in soft soils, reducing construction time for projects such as roads, railways, embankments, and reclamation works.   As an eco-friendly vertical drain solution, DAEHAN combines high performance, durability, and sustainability, supporting modern construction projects that value both engineering efficiency and environmental responsibility.   Features of Biodegradable Wick Drain 1. Eco-Friendly Composition Manufactured using biodegradable materials, the DAEHAN wick drain naturally decomposes over time, eliminating long-term synthetic waste. This makes it an ideal choice for environmentally sensitive areas and projects seeking green certification or sustainabi...

As a leading vertical drain manufacturer,   DAEHAN i.m 's Verti-Drain product line offers advanced solutions for soil improvement, drainage, and ground consolidation. By choosing DAEHAN, you gain access to engineered vertical drain systems designed for durability, performance, and fast deployment in demanding ground conditions. What is a Vertical Drain? A  vertical drain  is a pre-manufactured drainage element installed vertically into compressible soils (such as soft clays or dredged fill) to accelerate consolidation, improve bearing capacity and reduce long-term settlement. In practice, the vertical drain provides a short path for excess pore-water to escape, enabling faster stabilization of weak ground. Typical applications include land reclamation, foundation preparation for buildings, road/rail embankments, and port/harbour sites. Why Choose DAEHAN’s Verti-Drain as Your Vertical Drain Solution? Manufacturing expertise: As a specialist vertical drain manufacturer, DAE...

Hori-Drain® is a high-performance prefabricated horizontal drain developed by DAEHAN i.m. to enhance soil improvement and drainage in soft ground conditions. Designed with advanced engineering and eco-friendly principles, it significantly improves ground stability and accelerates consolidation processes. The product features an innovative pocket-style design, incorporating a durable polypropylene (PP) core and a nonwoven filter jacket to optimize drainage performance. Its unique mountain-shaped ( 山 ) core structure prevents filter intrusion into water channels, maintaining high drainage efficiency even under pressures up to 500 kPa. With a drainage capacity exceeding 3,500 cm³/s, Hori-Drain® ensures rapid pore water discharge. It also offers seamless compatibility with prefabricated vertical drains (Verti-Drain®), enabling integrated soil improvement solutions. As an eco-friendly alternative, Hori-Drain® replaces traditional aggregate layers like sand or gravel, supporting sustainabl...
