HVJ North Texas

HVJ Associates® North Texas

The Dallas office was established in 2005 to provide geotechnical engineering and construction materials engineering and testing services to  Dallas, Fort Worth, Waco, Tyler, Atlanta, Paris, Wichita Falls, Brownwood, and surrounding areas. Services are provided by HVJ North Texas - Chelliah Consultants, Inc., a proud independently owned and operated HVJ Associates® franchisee.

Geotechnical Engineering and Construction Materials Engineering and Testing Services

We use our geotechnical engineering expertise to assess specific site soil and groundwater conditions and design earth structures (slopes, channels, and dikes), foundations (retaining walls, bridges, buildings, tanks), and subsurface structures (clarifiers, lift stations, buried utilities, tunnels) to economically achieve the specific project objectives.

We engineer and test materials such as soil, concrete, and asphalt to help make sure you get what you pay for and that your project performs as well as or better than expected. Services include owner verification testing, pavement subgrade stabilization, and shrink-swell mitigation mix designs, and construction observation of drilled shaft, auger-cast-pile, driven pile, shallow spread footing, and mat foundations.
