Leading Prefabricated Horizontal Drain Manufacturer | DAEHAN i.m.

Image
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 speed...

High-Quality Silt Curtain Systems for Sediment Control | DAEHAN i.m.

Image
A silt curtain , also known as a silt protector or turbidity curtain, is a floating barrier installed in water to prevent the spread of suspended sediments and contaminants during marine construction activities. DAEHAN i.m. provides high-quality sediment control solutions, including advanced silt curtain systems designed to protect surrounding aquatic environments during dredging, coastal construction, and waterfront development projects. The curtain is vertically suspended in the water column to create a controlled zone that traps disturbed sediment and allows it to settle naturally at the seabed. By containing turbidity within a designated area, silt curtains help maintain water quality, protect marine ecosystems, and ensure compliance with environmental regulations during construction and engineering projects. Geos Silt Protector The Geos Silt Protector is a high-performance silt curtain system designed to effectively control sediment dispersion in aquatic environments. It is widel...

High-performance Biodegradable Wick Drains for Soil Improvement | DAEHAN i.m.

Image
DAEHAN i.m. provides high-performance biodegradable wick drain systems designed to accelerate soil consolidation and improve ground stability while minimizing environmental impact. Their wick drains are engineered for modern geotechnical and civil engineering projects that require both efficiency and sustainability.   Wick Drain: A wick drain , also known as a prefabricated vertical drain, is installed into soft ground to shorten drainage paths and rapidly dissipate excess pore water pressure. This process significantly accelerates soil consolidation, reducing settlement time before construction. Wick drains are widely used in: Ø   Soft clay and silt ground improvement Ø   Road and railway embankments Ø   Port, harbor, and coastal reclamation projects Ø   Industrial and residential land development   Biodegradable Wick Drain Technology DAEHAN i.m.’s biodegradable wick drains are developed using eco-friendly materials that naturally decom...

Silt Protector for Coastal Construction Works | DAEHAN i.m.

Image
Geos Silt Protector by DAEHAN i.m. is a high-performance silt curtain engineered to prevent environmental contaminants from spreading in water during coastal, river, and marine construction works. As an effective silt protector , it delivers proven sediment control with a minimum 45% to maximum 95% preventive effect, making it an essential solution for sustainable water quality protection and environmental compliance. What Is Geos Silt Protector? The Geos Silt Protector is a specialized silt curtain designed to contain and minimize the spread of suspended sediments and contaminants in water bodies caused by dredging, reclamation, inline construction, and other aquatic civil works. Installed vertically in water, this DAEHAN i.m. silt curtain acts as an effective barrier that slows sediment dispersion and protects nearby ecosystems. Built with robust floatation, high-strength canvas, and secure anchoring components, Geos Silt Protector is engineered to withstand waves, tid...

Bio Hori-Drain® – Eco-Friendly Biodegradable Horizontal Drain (PHD) | DAEHAN i.m.

Image
Bio Hori-Drain® from DAEHAN i.m. is an innovative biodegradable horizontal drain (PHD) engineered for efficient soil consolidation and sustainable ground improvement. Crafted to meet modern civil engineering requirements, this eco-friendly drainage solution accelerates the removal of pore water in soft soils while dramatically reducing environmental impact. What Is Bio Hori-Drain®? Bio Hori-Drain® is a prefabricated horizontal drainage system designed for installation in soft ground improvement projects. Unlike standard synthetic drains that remain in the soil after settlement, this drain is manufactured using biodegradable materials that naturally decompose underground after fulfilling their function, leaving no long-lasting waste. It works in concert with vertical drains to enhance the lateral discharge of pore water, helping accelerate soil consolidation — especially in land reclamation, embankment, road and rail foundation projects. Key Features and Benefits: Envi...
