Our highly skilled team provides customers with dependable, site-specific geotechnical and environmental drilling services every day.
- Drilling method used to drill boreholes into rock formations
- Most water wells and environmental monitoring wells drilled into bedrock are constructed using air rotary
In this drilling method, air is used to circulate and cool the drill bit, bring drill cuttings to the surface, and maintain the integrity of the borehole.
This is a great method to use on materials like cobbles and boulders since this process effectively moves through common obstacles that occur in such materials.
This drilling method saves time, is cost effective, and has a significantly lower impact on the environment.
Sonic drilling is ideal for providing undisturbed, continuous core samples in even the most challenging geologic conditions.
Sonic technology accomplishes the job faster and with less waste. With penetration rates one to four times faster than conventional drilling methods we can get the job done more efficiently, and with 70-80 percent less waste.
Additionally, rod handling technology increases productivity and creates a safer working environment by reducing the impact on field staff.
Advantages of direct-push technology:
- In certain types of soil, this method can produce a large number of high-quality samples quickly and cheaply, generally 100–200 feet per day.
- Small-diameter wells may be installed with this efficient technique.
Our GeoProbe® partners pioneered direct-push subsurface sampling technology in 1987. In this method of drilling, specialized machines “push” tools and sensors into the ground without needing to drill to remove the soil and make a path for the tool.
Rigs use hydraulic cylinders and a hydraulic hammer to advance a hollow-core sampler to gather soil and groundwater samples. This state-of-the-art technology allows us to probe through sand, gravel, hard pans, high-friction clay, tills, fill materials, and surface frost.
We use this technology for environmental investigation.
We specialize in monitoring-well projects and take pride in our record of delivering excellence. A monitoring well allows for periodic sampling and analysis of groundwater in order to detect any changes in the groundwater flow, level, and quality.
We use hollow-stem augers up to 8.25 in inches in diameter with air/fluid rotary to install monitoring wells up to 6 inches in diameter. You can depend on Hawkston to deliver current and accurate results so that you can continue your project without worry.
MONITORING-WELL DEVELOPMENT + ABANDONMENT
- Well development and pumping tests
- Wellhead protections—flush mount and stick up
- Wellhead replacement and rehab, with attention to site-specific detail
- Borehole and well abandonment, with attention to state-mandated regulations
- Post-run tubing
- Vapor implants
This form of sampling measures the gas contained in between the grains of soil, which is different from directly sampling the soil environment. What used to be a tedious and complicated task has become efficient with our post-run tubing, which makes it quick and safe to extract gas samples from any soil.
We utilize vapor implants to increase the safety and security of the tubing system, guaranteeing the joint is anchored within the depths of the ground. A PRT adapter and O-rings eliminate the concern of system leaks at threaded joints.
All of our drill rigs are equipped with automatic drop hammers and high-speed rotary heads capable of coring rock.
