Civil Construction Services

c.c. In the 30 years DeWind has been in the construction business they have developed an impressive list of services. Their Proprietary machinery and methodology has been fine tuned over decades, and their One-Pass Technology gives them unmatched precision, speed, safety and depth capabilities. All installations are executed under the static water table in a single pass, eliminating the need for dewatering and remediating of contaminated water. The One-Pass narrow trench cuts for environmental installations eliminate the handling and disposal of tons of extra-contaminated soils and the surgical technique allows for very deep collection, containment or remediation systems to be installed on tight, active and congested sites.

 
FAQ:
Who Is Dewind One-Pass Trenching?
In 1984 Greg DeWind and his wife opened DeWind Water Well Service which grew into a full-service construction dewatering business. In 1990, Greg built the first DeWind Trencher to be used for installing sock pipe for dewatering. Over time, Greg improved each trencher he constructed, adapting new technology that ultimately became the DeWind One-Pass Trencher. Greg’s focus was to engineer the trencher to be able to complete collection, containment and remediation systems in a single pass, avoiding the need to dewater, shore sidewalks and work near dangerous and deep excavations. This one-pass trencher would also eliminate the need to manage and dispose of tons of contaminated soils.
 
How does DeWind differ from other trenching solutions?
Simply put… Innovation. The DeWind One-Pass Trencher is designed and built by Greg DeWind from concept to completion. Using this ultra efficient One-Pass Technology results in less on-site equipment, minimizes project duration, reduces spoils and material Cost, does not require construction dewatering and BEST OF ALL… there is never an open excavation!

Testimonials
After pricing a conventional installation with construction estimates reaching near several million, we decided to call DeWind One-Pass Trenching and discovered that DeWind’s exclusive Trenching technology could install the vertical wells, the horizontal slotted pipe and the stone backfill 40′ deep in a single pass under the contaminated water table with a considerable reduction in spoils remediation.”
