About Us
Been There. Grouted That.™
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.
CJGeo is a second generation company run by three brothers; Dustin, Kevin & Kirk Roberts. Dustin is a superintendent, Kevin is VP of Operations, and Kirk is VP of Preconstruction.
