High-Performance Prefabricated Horizontal Drain (PHD) | DAEHAN i.m.

As a leading DAEHAN i.m. horizontal drain manufacturer, they provide advanced drainage solutions designed for efficient and cost-effective soil improvement. Hori-Drain®, their premium prefabricated horizontal drain, delivers exceptional performance in projects requiring rapid consolidation and reliable drainage capacity.

What Is Hori-Drain®?

Hori-Drain® is a pocket-style prefabricated horizontal drain (PHD) engineered to enhance soft ground by accelerating the discharge of pore water. Manufactured with a mechanically robust polypropylene (PP) core and wrapped in a durable nonwoven filter jacket, it is optimized for long-term stability and high-efficiency drainage in soil improvement and ground engineering applications.

Hori-Drain® works synergistically with prefabricated vertical drains (PVDs). It is connected to the exposed section of Verti-Drain® after installation, enabling rapid horizontal drainage of water discharged from vertical drains. This significantly speeds up soil consolidation compared to natural horizontal drainage layers such as sand or gravel.

Applications of Hori-Drain®

Hori-Drain® can effectively replace conventional aggregate-based horizontal drainage systems, offering superior installation efficiency and long-term reliability. Typical applications include:

Soil Improvement & Ground Engineering

• Replacement of sand or gravel layers in soft ground reinforcement
• Consolidation acceleration for road, railway, airport, and seaport developments
• Horizontal drainage for land reclamation projects

Surface & Structural Drainage

• Rainwater drainage systems
• Drainage for bank slopes to reduce pore-water pressure
• Back-wall drainage for retaining walls and concrete structures

Advantages of Using Hori-Drain®

1. Eco-Friendly Alternative: Reduces or eliminates the need for natural aggregates, helping preserve environmental resources.

2. High Economic Efficiency: Cuts construction costs by more than 30% through simplified installation and reduced material requirements.

3. Reliable and Stable Supply: Factory-produced materials ensure consistent quality and prevent delays caused by the instability of natural aggregate sourcing.

4. Easy and Flexible Installation: Lightweight and manageable—can be installed manually without heavy machinery.

5. Superior Drainage Performance

• Mountain-shaped core prevents filter intrusions
• High drainage capacity under heavy loading
• Efficient water collection due to ≥80% open area
