Horizontal Drains
Horizontal drain installation services are a targeted and cost-effective method of groundwater control and slope stabilization. These drains intercept and lower groundwater levels to improve stability and reduce hydrostatic pressure. We often install horizontal drains behind slopes or retaining structures to mitigate pressure on shoring systems.
Construction Process
Drill Tech installs horizontal drains within a large range of depths, at lengths between tens and hundreds of feet. The process begins with drilling a horizontal or inclined borehole, then installing a perforated pipe. Our team provides the option of wrapping the pipe in geotextile fabric. Finally, we collapse the borehole around the pipe, which creates a targeted groundwater flow through the drain.
Benefits of Use
Horizontal drains, when integrated into large earth retention systems or installed as standalone solutions, improve slope performance, extend infrastructure service life, and reduce maintenance costs.
Applicable Projects
Slope & Landscape Stabilization
Embankment & Roadway Drainage
Groundwater Relief Behind Retaining Walls
Tunnel & Portal Drainage
Excavation Dewatering
Dam & Levee Seepage Control
