Engineer-Founded. Field Proven.
Geotechnical Drilling Services
Founded by a geotechnical engineer and geologist, M&W Drilling was built on a deep understanding of subsurface conditions and drilling methods. Our geographic location exposes our crews to a wide range of geology, from heaving sands and complex karst formations to hard granite. That experience supports complex work such as data center and nuclear site characterization (under NQA-1 protocols), deep rock coring to depths exceeding 2,000 ft, HDD feasibility drilling, and projects at DOE facilities.

Hole Abandonment
When investigative borings and test holes are no longer needed, they must be properly closed to prevent a pathway for contaminants into and throughout the subsurface. M&W Drilling performs hole abandonment services that permanently seal old borings with field-tested sealing practices and clear documentation tailored to project requirements.

Monitoring Well Installation
Monitoring wells serve as a critical window into the subsurface by tracking groundwater quality, movement, and contamination over time. M&W Drilling installs monitoring wells engineered for your project’s depth, materials, and sampling goals.
Extraction Well Installation
Extraction wells are used to remove contaminated groundwater for treatment and cleanup. M&W Drilling installs extraction wells that meet strict environmental and regulatory standards.
Injection Well Installation
Injection wells deliver fluids such as amendments or reagents into the subsurface for remediation. M&W Drilling installs injection wells designed for accurate placement and regulatory compliance.
Dewatering Well Installation
When excavation or construction meets groundwater, dewatering wells create dry, stable work zones and prevent flooding or soil instability. M&W Drilling installs dewatering wells that temporarily lower the water table to protect foundations, utilities and underground structures.
Standpipe Piezometer Installation
Standpipe piezometers provide a reliable and cost-effective method for monitoring groundwater levels and pore water pressure in soil and rock. M&W Drilling installs standpipe piezometers using proven drilling methods to ensure accurate readings and long-term performance. These systems are commonly used for geotechnical investigations and slope stability monitoring.
Vibrating Wire Piezometer Installation
Vibrating wire piezometers provide precise, real-time measurements of groundwater pressure in soil and rock. M&W Drilling installs vibrating wire systems designed for long-term monitoring and high-accuracy data collection in demanding geotechnical environments. Our installations support critical applications such as dam safety, slope stability analysis, excavation monitoring, and infrastructure projects.
Inclinometer Installation
Inclinometers are essential for tracking ground movement and subsurface deformation over time. M&W Drilling installs inclinometer casings for slope stability, embankment monitoring, and structural performance analysis.
Pump Testing
Pump Testing measures how a well and an aquifer respond to sustained pumping. M&W Drilling conducts these tests to measure yield, drawdown, and recovery, providing data that supports system design, performance verification, and long-term groundwater management.
Packer Testing
Packer tests measure how groundwater flows through specific rock or confined zones. This data is critical for evaluating site hydrogeology and permeability. M&W Drilling performs single- and double-packer tests that deliver accurate, defensible results for environmental projects.

About Geotechnical Drilling
Geotechnical Drilling: What is it?
Geotechnical drilling is the process of drilling into the ground to collect soil and rock samples so engineers can understand subsurface conditions and design safe, stable foundations and structures.
Does M&W Drilling provide engineering testing services?
No, M&W Drilling focuses solely on the drilling portion of geotechnical investigations. However, we work closely with many geotechnical engineering firms across the country and would be happy to connect you with a trusted partner.
What experience does M&W Drilling have working on highly regulated or sensitive sites?
M&W Drilling has extensive experience working on highly regulated and high compliance sites. Our team has performed geotechnical drilling ranging from shallow 10 ft SPT sampling to 400 ft HQ3 rock coring at facilities such as DoE, NQA-1, and DoD sites, where strict safety, documentation, and compliance standards are required.
