About Us

Skyline Dredging & Excavating Inc. stands as the proven leader in skyline dredging services, building custom dredge that reach over 200 foot depths and 2000 foot spans from solid ground, hauling 15 to 30 tons of aggregate per drag to unlock untapped material without expanding your footprint or compromising safety. Since 2003, we have recovered over 4 million tons for gravel pit excavation, copper mine leaching, mineral mining dragline operations, and environmental reclamation dredging projects across the country, delivering MSHA compliant operations that minimize risks, maximize efficiency, and respect the land for generations. We are not just custom dredge builders, we are partners in your production, testing every machine with 100000 tons before shipment to ensure deeper digs, safer sites, and results that drive your profits in aggregate recovery and water reclamation projects.

Born and Tested in Western Montana

Forged in the rugged downturn of Montanas logging industry, Skyline Dredging & Excavating Inc. emerged in 2003 when founder Mark Herzog sketched the first skyline dredge to tackle deep aggregate recovery that traditional methods could not touch. Tested on the unforgiving terrain of Western Montanas gravel pits and waterways, our machines proved their grit through real world pulls, adapting to slopes, swamps, and underwater challenges while prioritizing crew safety and minimal environmental impact. Those Montana born lessons, work hard, shoot straight, value your crew and clients, get the job done with no excuses, guide every build and contract we take on, ensuring our dredge deliver the same old school reliability and innovative edge for skyline dredging services nationwide.

Our expertise runs deep in custom dredge construction, where we engineer machines to haul 15 to 30 tons per drag across spans over 2000 feet and depths beyond 200 feet, all from stable ground to eliminate edge risks in gravel pit excavation and mineral mining dragline ops. With over 4 million tons recovered nationwide for aggregate recovery Montana sites, copper mine leaching methods, and environmental reclamation dredging, we specialize in adapting our skyline style dredges for tough applications like accessing material under ponds or pulling slopes to grade in high stakes mining environments. Every build incorporates MSHA compliant safety features and field tested innovations that minimize land disruption while maximizing your pits production, turning untapped aggregate into real profits without compromising the terrain—ideal for contractors and government agencies seeking efficient water reclamation projects.

We bring hands on knowledge from partnerships with industry leaders like TMC, Knife River, and Phelps Dodge Morenci, where our dredges have laid leach lines in minutes, repaired erosion damage, and reclaimed waterways with precision that respects environmental regulations. Our team offers turnkey contracting or consulting services to get your operation running smooth, from equipment sourcing and setup to operator training that sticks for skyline dredging services and custom dredge builders. Built on Montana tough values, our expertise ensures safer sites, deeper digs, and proven results that honor your legacy and drive efficiency for generations in gravel pit excavation, copper mine leaching, and beyond.
