Windowless Sampling & Commitment to Safety
Windowless Sampling is a specialist technique carried out using percussive or pneumatic samplers, commonly used for soil investigations and the installation of groundwater monitoring wells. This method is efficient, non-invasive, and ideal for a range of environmental and geotechnical applications.
At DMW Drilling, we hold a variety of industry-recognised certifications, including:
NVQ Level 2 in Land Drilling
Emergency First Aid at Work
CSCS Cards
CHAS Accreditation

All members of our team are highly trained and experienced in safe working practices, ensuring that every project is completed to the highest safety standards. Our strong safety record and commitment to meeting deadlines provide clients with the confidence that their project is in reliable hands.

Window Sample Rig
Our Window Sampling Rig is a compact and efficient solution for shallow-depth geotechnical and environmental investigations. Ideal for restricted access or sensitive sites, it allows for the recovery of undisturbed soil samples with minimal disruption. Perfect for sites with limited headroom or where low-impact drilling is essential.

Modular Rig
The Modular Drilling Rig is designed for use in locations where space or access is limited, such as basements, back gardens, or indoors. Built from lightweight, transportable components, it can be carried through tight spaces and assembled on-site. This makes it a practical option for window sampling, dynamic probing, or shallow rotary work in difficult-to-reach areas.

Electric Pack
Our Electric Power Pack is compatible with both the Window Sampling Rig and Modular Rig, offering a quiet, low-emission alternative to traditional power sources. Ideal for indoor or noise-sensitive environments, the electric pack delivers reliable performance without compromising on power or efficiency—making it perfect for urban or restricted-access projects.
