Geotechnical site investigations are used to determine existing ground conditions, underlying geology, and hydrology. We use a wide range of drilling, soil sampling, and in-situ sampling techniques to provide data for engineering and design. This data can then be used to determine the type and use of preventative measures to mitigate possible settlement, soil movement, or the presence of groundwater that may adversely impact existing or proposed structures.

Your team at Holt Services Inc utilizes state-of-the art equipment and instruments to conduct your geotechnical testing with accuracy and to exacting standards.

Founder Randy Holt started his first clean water drilling company in 1979 and built a solid reputation for dependability, quality work, and results.

Holt Services, Inc. utilizes state-of-the-art Direct Image Systems from Geoprobe Systems to vertically log in-situ conditions to a depth of 100 ft. bgs.


In-situ chemical injection projects by nature are complex and offer many challenges. Which is why we work with the client to understand the goals of the project and how to safely achieve those goals.

Holt has a large fleet of drill rigs and the ones we use for injection projects will vary based on site and subsurface conditions. We have truck and track mounted Geoprobe direct push rigs along with a fully-enclosed, self-contained injection trailer with an 11kw generator.

At most drill sites, concerns exist about potential underground utilities or obstructions. Drilling into utilities or obstructions carries safety risks, can result in costly repairs and cause project delays. There is an easy solution for uncovering utilities and obstructions before drilling begins. At the borehole location, use our air knife vacuum truck to air excavate ("pothole") or probe to a depth of up to 12 feet to physically locate utilities and obstructions.

The air knife vacuum truck safely uncovers underground utilities and obstructions. It quickly digs deep down with air, locating underground utilities in the hardest soils without harming them.
