Greg and Becky DeWind started their business in the construction dewatering business nearly thirty years ago. Today, their business has expanded into a full service shop specializing in underground problem solving through the development of the DeWind One-Pass Trenchers, the world’s most capable and deepest reaching trench.

Greg DeWind is recognized as an industry leader in the engineering and manufacturing world. Working out of several fabrication shops in Holland Michigan, DeWind employ a large team of highly skilled machinists, welders, mechanics and operators that build and maintain the inventory of custom machines including: Trenchers, All Terrain Construction Vehicles, Custom Drill Rigs, High Pressure Jet Rigs, and other custom problem solving equipment used in the construction dewatering and deep trenching industries.

DeWind’s ability to solve complex engineering problems across a diverse spectrum of conditions has been the driving force behind their success. For three decades, their pursuit of innovation has resulted in improved techniques while consistently delivering reliability, every time.

Every DeWind One-Pass Trencher is custom built and has phenomenal depth capability, power, dependability and is safe. The meticulous engineering of the DeWind One-Pass Trenchers is a cost-savings when performing deep trenching and is environmentally friendly.


DeWind’s One-Pass Trencher is built using unique and revolutionary technology. This trench allows the installation of deep containment walls, groundwater and product recovery trenches, permeable reactive barriers, soil vapor or injection trenches to be installed underground, under the water table and IN A SINGLE PASS. There is no need to pump, treat, shore, or dig mass excavations! It also eliminates the need for dangerous deep and wide-open excavations. The installations are fast, surgically precise, and can be completed on the most challenging job sites such as between structures, under overpasses; on levees- anywhere conventional excavation equipment would be inconceivable.

The DeWind One-Pass Trenchers and attachments are custom designed. Each trencher is a track-mounted machine that has a cutting boom resembling a large chain saw. Horsepower ranges from 750 to 2000, making them the deepest, most powerful unconsolidated soils trenchers available in the world.

All trenchers have interchangeable cutting booms and can cut a nominal 12, 24, 36 and 48 inch wide trench. Trench depths vary depending on the size. Trencher and systems installed from 0 to 45 feet deep for backfilled trenches to In-situ mixed soil bentonite walls can be installed up to 80 feet. Dual laser-guided systems ensure a precise, automatic depth control of the cutting boom during installations and GPS tracking can map the system as it is being installed.

The DeWind One-Pass Trenchers allow engineers to design solutions that can be installed in a single pass using far less equipment and in a shorter amount of time. The technology improves safety by eliminating the need for open pit excavations.

DeWind’s unwavering commitment to safety is accomplished by extensive training. All DeWind Trencher Operators are initially trained as mechanics to ensure a solid understanding of welding, metal fabrication, electrical and hydraulic systems. This level of training promotes a safe work environment by building a comprehensive understanding of the equipment and its abilities.

DeWind offers crews fully trained for work on hazardous waste sites, and all operators and laborers are 40-hour OSHA trained with a current 8-hour refresher. We will operate under a Health and Safety Plan that is in compliance with 29 CFR 1910.120 and other OSHA requirements.
