CJGeo, Inc. is a Virginia-based specialty grouting and lightweight fill contractor serving the industrial, commercial, and public markets. We work pretty much everywhere east of Texas.

In November 2025, CJGeo became a second generation when brothers Dustin (VP of Construction), Kevin (Chief Operation Officer), and Kirk Roberts (Chief Executive Officer) purchased it from their father Preston H. Roberts.

CJGeo, originally Preston H. Roberts, Inc., was founded in 2002 as a residential site work contractor in Williamsburg, Virginia. We entered the grouting industry in 2008 as Concrete Jack, performing residential mudjacking. CJGeo was named in 2016 to differentiate our commercial, industrial and public sector work from our other operations.

In 2023, Concrete Jack was spun off as a separate company from CJGeo, solely performing concrete replacement & repair in the multi-family market. In 2024, the corporation’s name changed from Preston H. Roberts, Inc to CJGeo, Inc.
