Our Team

VACMASTERS, the leader in air-vacuum excavation, has been a family-owned and operated engineering and manufacturing company for almost sixty years. Vacuum excavation systems is our primary business. Our dedication to excellence over the years has made us the leader in air-vacuum excavation systems for underground utility locating.

We’ve designed and developed high-velocity proprietary nozzles for our systems and all engineering and fabrication stays in house for quality control. The four air-vacuum excavation systems that we design, develop, and manufacture — the SYSTEM 1000, SYSTEM 3000, SYSTEM 4000, SYSTEM 5000, and SYSTEM 6000 — dig potholes and perform trenching jobs in a matter of minutes using high pressure air. Potholes are used for exposing underground utilities, environmental soil sampling, and pipeline maintenance. We also manufacture and sell factory-direct the SpoilVac hydro-vac system used in directional boring.

Our Reputation Mean Everything.

VACMASTERS enjoys a hard-earned reputation for honesty, integrity and quality both in the way we manage our air-vacuum excavation equipment manufacturing business and in our relationships with customers and employees.

We are a customer-driven organization who listens to your concerns and then designs, engineers, and manufactures our air-vacuum excavation systems to satisfy those needs.

Our six decades of manufacturing is testament to our dedication to customers — utility, potholing, environmental, and construction companies — putting you first and delivering value-laden air-vacuum excavation equipment for locating underground utilities at fair and honest prices. We take pride in our company and hold high the trust you place in us by becoming our customer.

One of our customers was so pleased with his experience with VACMASTERS that he felt compelled to leave an anonymous voice-mail after hours. Here is what he had to say: “…Just over a year ago we purchased a SYSTEM 4000 from VACMASTERS and it has far exceeded everyone’s expectations. On top of that, your customer service has been top notch… We would recommend you to anybody.”

We strive to make sure every customer feels this same way. Most importantly, we are here when you need us and are only a toll-free call away for sales, support or service.

“We install and service more than 10 million feet of energy distribution systems annually, making us the recognized industry leader. As part of our work, we have to know what’s down there, and we can’t damage any utilities while we’re trying to find out.  Potholing with a VACMASTERS system is more economical than water because we can dig a hole faster, with no mud hauling or disposal, no returning with backfill, and no road base or underground utility damage resulting in costly claims. Air is non-conductive so it’s definitely safer for our operators. VACMASTERS also gives us great factory support and even trains our people.”

Todd Davisson • Sr. Manager–Purchasing and Assets, NPL Construction Company

“We’ve done a lot of potholing for the oil and gas companies here in West Texas using four of VACMASTERS’ System 4000 air-vacuum excavators. When they built the new SYSTEM 6000, we bought the first one right off the shop floor. It’s the most powerful air-vacuum excavation system in the world and it will even dig trenches with air. All VACMASTERS’ air-vacuum excavators vacuum up the dry soil as they dig so we can back-fill with the same spoils right away, saving time and money. The remote-operated boom arm on the 6000 makes it easy for a two-man crew, and our guys really like the hydraulic, full-opening rear door for easy dumping and cleaning. VACMASTERS trains us on their systems and when we need technical support, they’re just a phone call away.”

Dave Campbell • Owner-President, Air-Vac Systems, LLC

“Using the Federal Highway Administration’s Subsurface Utility Engineering (SUE) protocol and with the help of VACMASTERS Systems, we are able to visually locate underground utilities for our clients in the design stages of projects, before construction, avoiding costly utility conflict or construction delays caused by unknown or misrepresented utilities. Their dry excavation systems mean we don’t have to use high-pressure water, which is not only capable of cutting the utility, but is also dangerous to operators because it is conductive.”

Jim Gellenthin, PLS • Vice President, KCI Technologies, Inc.

“Underground Solutions locates utilities quickly and accurately with Vacmasters advanced air-vacuum excavation systems. They deliver high-pressure supersonic air through a special nozzle that explodes the soil from within that makes for easy backfilling with the same dry spoils. Air is non-disruptive, with no damage to the road base and there’s no need to haul off mud and return with fill dirt. We pay a little more for one of Vacmasters Air Vacuum Systems but it pays for itself with each job that we do.  That’s why we have four and hope to order more soon.”
