Leading Prefabricated Horizontal Drain Manufacturer | DAEHAN i.m.

DAEHAN i.m. a leading horizontal drain manufacturer provides the innovative Hori-Drain® prefabricated horizontal drain (PHD) system designed for effective soft ground improvement and drainage applications. Hori-Drain® is engineered with a mechanically strong polypropylene (PP) core and a specialized nonwoven filter jacket, ensuring reliable performance in soil improvement projects. This advanced drainage solution accelerates soil consolidation by facilitating rapid drainage of pore water discharged through prefabricated vertical drains (PVDs) installed in soft ground.

Hori-Drain®:

Hori-Drain® is a pocket-style prefabricated horizontal drainage system used in geotechnical engineering and ground improvement works. It is installed by connecting it with the exposed portion of a prefabricated vertical drain after installation.

This creates a continuous drainage path that efficiently transports water from vertical drains to the discharge outlet. As a result, Hori-Drain® significantly speeds up soil consolidation and improves the stability of soft ground.

Compared with conventional drainage methods that rely on sand or gravel layers, Hori-Drain® offers a high-performance engineered drainage solution that reduces the need for natural aggregates.

Key Advantages of Hori-Drain®

Workability and Economic Efficiency

Hori-Drain® offers several advantages for soil improvement and drainage projects:

  • Eco-friendly technology that replaces or significantly reduces the use of natural aggregates such as sand and gravel.
  • Over 30% reduction in construction costs compared to traditional drainage methods.
  • Stable supply through factory production, preventing construction delays caused by material shortages.
  • Simple installation by manpower, eliminating the need for heavy equipment.
  • Lightweight design for easy transportation and handling.

Performance and Drainage Capacity

Hori-Drain® is engineered to provide reliable drainage performance even under heavy loading conditions.

  • Drainage capacity exceeding 3,500 cm³/s under loading at 500 kPa.
  • Open water channel structure for efficient drainage.
  • Effective water collection area of at least 80%.
  • Outstanding load dispersion performance.
  • Consistent long-term drainage functionality.

Applications of Prefabricated Horizontal Drains

Hori-Drain® is widely used in infrastructure and geotechnical engineering projects that require effective soil consolidation and drainage.

Typical applications include:

  • Soft ground stabilization
  • Highway and railway embankments
  • Land reclamation projects
  • Port and harbor construction
  • Industrial and commercial site development
  • Airport infrastructure projects
  • Large-scale ground improvement works

These systems help accelerate soil consolidation and significantly reduce construction timelines.

Silt Curtain and Silt Protector – Effective Solutions for Sediment and Erosion Control | DAEHAN i.m.

Image
The silt curtain and silt protector are essential geosynthetic barriers used to control the movement of suspended sediments and fine particles during dredging, reclamation, and marine construction works. These systems create an enclosed area that reduces water velocity, promotes sedimentation, and prevents pollution from spreading to nearby ecosystems. Whether for coastal, river, or lake projects, DAEHAN i.m. silt curtain and silt protector deliver reliable performance, helping contractors meet environmental regulations and maintain water quality standards. Silt Curtain: A silt curtain, also known as a turbidity curtain, is a flexible geosynthetic barrier designed to contain suspended sediments in a specific area of water during dredging or construction. Installed vertically from the water surface to the bed, it prevents silt from drifting into surrounding waters. Silt Protector: A silt protector is a geosynthetic system that acts as a sediment barrier during ma...
