SB GeoTechnic’s superior reputation was founded on our expertise and achievements of installing horizontal drains for landslide stabilization and prevention in a wide range of soils and rock with all types of accessibility challenges.
Our successful techniques and the equipment we’ve designed and manufactured have accelerated the use of horizontal drains around the world. SB GeoTechnic has installed drains up to 1500 feet in depth that range from 30 degrees below horizontal to 60 degrees above horizontal. Our drains have produced satisfactory results in virtually all types of geologic formations.
SB GeoTechnic is prepared to travel worldwide to pursue projects requiring horizontal drain installations. We are also available for consulting on the use of horizontal drains for slope stabilization. Please contact us for feasibility and price estimates.
Hori-Drain is a pocket style Prefabricated Horizontal Drain (PHD) that improves soft ground. It is made of a mechanically strong PP core and a nonwoven filter jacket that is specialized for soil improvement and drainage works. Hori-Drain expedites soil consolidation by facilitating rapid drainage of pore water discharged through vertical drains installed in soft ground.
Horizontal Drain can be used for replacing the horizontal drainage layer of natural materials such as sand or gravel in soil improvement works and various drainage applications.
Replacement of sand or gravel layer for soft ground improvement
Land development for road, railway, airport and seaport
Drainage of rain water
Drainage of bank slopes and dissipation of water pressure
Back wall drainage of retaining walls and concrete structures
Eco-friendly technology that replaces or reduces the use of natural aggregate
High economic efficiency reducing construction cost by more than 30%
Stable supply through factory production (prevention of construction delay due to unstable supply of materials)
Easy installation by manpower without heavy equipment
Core structure of 山 shape to avoid filter insert to water channels under surcharge
High drainage capacity of over 3,500 cm3/s under loading at 500kPa
Open structure of water channels and great efficiency of drainage with an effective area of water collection by at least 80%
Outstanding load dispersion
