Hori-Drain® is manufactured by DAEHAN i.m. a trusted horizontal drain manufacturer specializing in advanced geosynthetic drainage systems for civil engineering, infrastructure, and land development projects worldwide.
What is Hori-Drain®?
Hori-Drain® is a high-performance horizontal drain system designed for efficient groundwater drainage and soft ground improvement applications. It is engineered to improve soil stability, reduce excess pore water pressure, and support long-term infrastructure performance in challenging geotechnical environments.
What is a horizontal drain system?
A horizontal drain system is designed to collect and discharge groundwater or excess pore water horizontally from soil layers. It helps improve soil stability, accelerate drainage, and prevent water accumulation in construction and ground improvement projects.
Applications of Hori-Drain®
Hori-Drain® is an advanced horizontal drainage system designed to replace conventional drainage layers made of natural materials such as sand or gravel in soil improvement and drainage works.
Main Applications
Replacement of sand or gravel drainage layers for soft ground improvement
Land development projects for roads, railways, airports, and seaports
Rainwater drainage systems
Drainage of embankment slopes and dissipation of water pressure
Back-wall drainage for retaining walls and concrete structures
