McGuireWoods advised Mascarene Partners, a middle-market infrastructure investment platform focused on North American transportation and industrial businesses, in the acquisitions of General Drilling Inc. from Fred Weber Inc. and Venture Drilling East. The companies were combined to form Iron Pillar United Mining Group.
Iron Pillar, headquartered in Conyers, Georgia, provides drilling services to aggregate producers and quarry owners across the Southeast and Midwest. The combination unites two established drilling specialists under one brand, creating a larger platform to serve the U.S. aggregates industry. The transaction closed May 14, 2026.
Partners Tom Zahn, Jason Griffith and Brian Coughlan and associates Andrew Steiger and Robert Morlock led the McGuireWoods team. Additionally, partner Gretchen Woodruff advised on employment matters; partner Shahrooz Shahnavaz on tax issues; and partner Phillip Coover on infrastructure and real estate aspects of the deal.
“This deal reflects exactly what McGuireWoods does best – bringing together cross-disciplinary teams to guide clients through multi-faceted transactions,” said Zahn. “We’re proud to support Mascarene Partners as they build Iron Pillar into a leader in the aggregates drilling space.”
