Advanced Prefabricated Horizontal Drain for Soil Improvement | DAEHAN i.m.

Hori-Drain® is a premium prefabricated horizontal drain (PHD) engineered for efficient horizontal drainage and soil improvement in civil and infrastructure projects. Designed and manufactured by DAEHAN i.m., Hori-Drain® offers superior performance, cost savings, and reliable quality compared to traditional natural aggregate drainage systems.

Hori-Drain®

Hori-Drain® is a pocket-style prefabricated horizontal drain that rapidly discharges pore water in soft ground conditions. Made with a mechanically strong polypropylene (PP) core and a specially engineered nonwoven filter jacket, it accelerates soil consolidation by efficiently draining water discharged from vertical drains installed in the ground.

Unlike traditional horizontal drainage layers made from sand or gravel, Hori-Drain® connects easily with prefabricated vertical drains (Verti-Drain®) to form a complete drainage solution that boosts project performance and sustainability.

[Key Features and Benefits]

High-Performance Drainage

  • Engineered core structure prevents filter intrusion and maintains drainage integrity under pressure.
  • Delivers high drainage capacity (≥3,500 cm³/s) even under heavy loads, ensuring rapid pore-water removal.

Economical and Easy to Install

  • Replacement or reduction of horizontal layers made of sand or gravel significantly cuts construction costs by more than 30%.
  • Factory production ensures uniform quality and availability, preventing delays due to inconsistent aggregate supply.
  • Designed for manual installation without heavy machinery, reducing labor expenses and site complexity.

Eco-Friendly Solution

  • Replaces natural aggregates, reducing environmental disruption and supporting sustainable construction practices.

Applications of Hori-Drain®

Hori-Drain® is ideal for a variety of drainage and geotechnical applications, such as:
✔ Replacing sand or gravel layers for soft ground improvement
✔ Land development for roads, railways, airports, and seaports
✔ Rainwater drainage and surface management
✔ Bank slope drainage for pore water pressure relief
✔ Back drainage behind retaining walls and concrete structures

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...
