DAEHANi.m.

  DAEHAN i.m. introduces Bio Verti-Drain®, an innovative biodegradable Prefabricated Vertical Drain (PVD) developed for environmentally responsible soft ground improvement. This next-generation product reproduces the proven performance of conventional Verti-Drain® systems while eliminating long-term environmental impact. After installation and soil consolidation, Bio Verti-Drain® naturally degrades in soil without leaving behind any residual plastic materials. As the first biodegradable vertical drain to receive the “Eco-Label” certification from the ministry of environment of Korea, Bio Verti-Drain® marks a breakthrough in sustainable geotechnical engineering and green construction technology. Eco-Friendly Composition Bio Verti-Drain® is composed of Poly Butylene Succinate (PBS)—a high-performance, aliphatic polyester—and Polylactic Acid (PLA) derived from cornstarch sources. Both materials are fully biodegradable, decomposing into water (H₂O) and carbon dioxide (CO...

DAEHAN i.m. is a leading provider of advanced geotechnical drain systems designed to improve soil stability, accelerate consolidation, and enhance the performance of weak ground. Their cutting-edge drainage technologies — including the innovative wing horizontal drain — provide efficient and reliable solutions for managing pore water pressure and promoting rapid ground settlement in civil and geotechnical projects. Whether for highways, embankments, reclamation sites, or industrial developments, DAEHAN delivers high-performance drainage products that ensure long-term stability, durability, and cost-effective construction outcomes. A geotechnical drain is a specialized drainage system used in ground improvement applications to remove excess pore water from soft or saturated soils. By facilitating water discharge, geotechnical drains accelerate soil consolidation, reduce settlement time, and significantly improve the bearing capacity of the ground. DAEHAN geotechnical drains are...

DAEHAN i.m. Geos Mat is a high-performance polyester and polypropylene woven geotextile designed for soft ground improvement , soil reinforcement, and layer separation. Engineered with precision and durability, Geos Mat enhances soil stability, prevents differential settlement, and ensures long-term structural integrity in infrastructure and geotechnical projects. Available in three specialized product series – GM, GML, and GMP – Geos Mat offers optimized solutions for various field conditions and engineering requirements. Why Geos Mat for Soft Ground Improvement? Soft or weak ground often lacks sufficient bearing capacity, resulting in settlement, instability, or deformation under load. The Geos Mat geotextile acts as a reinforcement and separation layer, distributing loads evenly and improving the overall performance of soil structures. Geos Mat Product Series The Geos Mat GM Series is a polyester woven geotextile made from high-tenacity polyester filament yarns wo...

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...
