About Us
What is DryJect®
DryJect is a one-step service that combines the agronomic benefits of aeration, soil amendments, and topdressing all in one easy, simultaneous service. With minimal cleanup, we leave your golf course or athletic field in playable condition, in most cases. Following a DryJect service, playing surfaces are clean, smooth, and free from plugs. No messy cores to clear up. Virtually no downtime nor lost revenue due to facility maintenance closures.
How it Works
DryJect’s patented high-pressure water-based injection system creates aeration holes through the root zone to fracture the soil while its pioneering vacuum technology simultaneously fills holes with sand, peat, or other soil amendments.
Use in Tandem With or In Place of Traditional Aeration
With DryJect added to your maintenance program, you can improve your existing program and possibly reduce the number of coring events. Incorporating DryJect into your existing aerification schedule, especially after a deep tine event, magnifies the benefits of deep tine aeration.
No Large Capital Investment
As DryJect is a service, there’s no large capital outlay, or special employee training required. DryJect independent franchise service providers expertly operate the equipment, leaving most of your staff to fulfill routine tasks.
Recapture Lost Revenue
As DryJect is virtually invisible, there’s little to no lost revenue from the kinds of long-term post-treatment closures you experience with core aerification. Turfgrass is ready to play almost immediately. Dryject’s less disruptive approach to aeration means that playing surfaces are ready faster, and overall healing time is reduced. Just DryJect and go.

“We have been using DryJect for over five years, and it has completely changed our approach to aerification! Getting to those hard-to-reach areas with traditional aerators just wasn’t cutting it for us anymore. Hitting our target areas while leaving the putting surface in premium condition has been a game-changer. DryJect is now a regular part of our annual aerification program.”
Greg Greer, Course and Property Manager

“We couldn’t be happier with the results from DryJect. Our greens are firm, and we have eliminated all conventional aerification and in-season topdressings. As a public golf course, revenue is important, and with DryJect, we close two days a year for greens aerification. We never have complaints or disappointment from our customers from playing on sandy aerified greens. The day after we are done, the greens are open and rolling true and smooth. Initiating a DryJect program at Saratoga National is by far the best decision I have made.”

The DryJect® Story
TODAY

With DryJect, company owner John Paddock combines a love of engineering with a passion for turfgrass management.
Like many of DryJect’s service center franchisees, John Paddock, owner of DryJect, Inc., has had a long career in golf, landscape maintenance, and agriculture. He grew up in a farming community, driving tractors as a youngster. At his first summer job on a golf course in Connecticut—which combined his love of the outdoors with golf and technology—he learned from a co-worker that he could get a degree in turf management. He quickly changed his plans to study engineering, applied to Penn State University’s turf program, got married and moved to New Jersey to begin his career as an assistant superintendent. John progressed in his career, earning positions as superintendent at golf courses in New Jersey, including Shark River Golf Course in Neptune, NJ. One of the founders of DryJect, Peter van Drumpt, lived nearby. John and Peter developed a friendship. Peter frequently used John’s golf course to demonstrate the machine to customers. Over time, John also started his own irrigation and landscaping company. Eventually, the two friends realized they should work together. John joined the staff of DryJect as a shop tech, but it became apparent his true passion was in the design of the machine and management of the company. Five years later, when DryJect’s owners were ready to retire, John was their natural successor. He purchased the business in 2016.
The Founding of DryJect®
DryJect was founded in 1998 by Peter van Drumpt and Chris des Garennes. At the time, the men already co-owned a soil amendment company together. Additionally, Peter is an avid golfer and Chris is a former golf course superintendent. DryJect’s technology was originally developed for use in agriculture to aerify around fruit trees. When Peter and Chirs saw the early prototype of the machine, they both knew the real potential of the machine was in turfgrass management. They bought the rights to the technology, patented their modifications to it, and started DryJect. The founders believed the best way to gain market acceptance was to encourage as many turfgrass managers as possible to experience the agronomic benefits of DryJect’s injection system at their facilities through a contract service provided by franchisees. They set up headquarters in Hatboro, PA, and began licensing other turfgrass professionals to become independently owned DryJect Service Center franchisees. Today, thousands of golf courses and sports fields around the globe regularly incorporate DryJect into their soil health and turfgrass management programs.
