Built on grit.Driven by expertise.
IronPillar United Mining Group brings together two long-standing drilling specialists under a single brand — creating a scaled drilling services platform serving the U.S. aggregates industry.
Two Drilling Leaders.One Unified Platform.
IronPillar United Mining Group was formed through the combination of General Drilling Inc. and Venture Drilling East, uniting two respected drilling specialists under a single brand. Headquartered in Conyers, Georgia, IronPillar provides drilling services to aggregate producers and quarry owners across the Southeast and Midwest.
Backed by Mascarene Partners, a middle-market infrastructure investment platform, and with continued ownership from Fred Weber and the former owners of Venture Drilling East, IronPillar is built for long-term growth — both organically and through additional acquisitions.
- Blast-hole drilling services for stone quarries and aggregate producers
- Fleet of 100+ track- and truck-mounted drill rigs
- Serving quarry customers across Indiana, Kentucky, Ohio, Illinois, and the Southeast
