Horizontal Drains

Horizontal Drains

Engineered Drainage Systems for Mining, Landslide Mitigation & Slope Stability

At GeoStabilization International (GSI), we design and install advanced horizontal drain systems to control groundwater, prevent slope failures, and extend the operational life of critical infrastructure. These systems are especially valuable in mining environments, where subsurface water pressure poses a significant risk to highwall integrity, pit slopes, haul roads, and tailings facilities.

With proprietary drilling rigs, a specialized focus, and a track record of above-industry production standards, GSI delivers drainage solutions quickly and effectively across the U.S.
