Vacuum Excavating

Vacuum Excavating

In today’s world the term excavating is rapidly evolving, from the advances in trench-less technology to the emerging popularity of vacuum excavating we are certainly altering the perception of “traditional” excavating. For those of you who are curious about the advantages of vacuum excavation, this is for you.

Portland, Oregon and Washington have seen tremendous growth around the utilization of vacuum excavation services since the mid 90’s. The popularity stems from a variety of reasons that range from environmental protection to increasing jobsite safety and efficiency.

This is how it works. A tank mounted on either a truck or trailer is used to capture the material just like a vacuum bag, these tanks range in size. Material is sucked up through a hose attached to the top of the tank, which can range in size from 3″ to 12″. A wide variety of materials can be captured using this process. A water knife (basically a pressure washer) is often used to cut the debris into a manageable size or consistency to help work material through the suctioning hose and into the vacuum excavator’s storage tank. A hatch on the back of tank is utilized to remove the material from inside the tank and dumped at an approved disposal site.


Common applications for the vacuum excavating process are utility pot-holing, hydro-jetting, car wash debris extraction, trenching/excavating, grease trap cleaning, tank cleaning, confined space entry preparation and assistance, storm filter cartridge cleaning, replacement and installation, tunneling, sewer pump station maintenance, catch basin cleaning and spoil or waste removal.
