Using Hydro Excavation for Potholing/Daylighting

Underground facilities like pipes and sewer systems require maintenance just like everything else, but accessing those underground facilities can be a bit of a hassle. The process of digging a small hole to expose a portion of the facilities is called daylighting or potholing, and it is necessary to look for any issues that will need to be resolved, like cracks or other damage. One of the most common methods for digging such a hole is known as hydro excavation, and it is exactly what it sounds like.

Hydro excavation or “potholing” is the process of using water under high pressure to dig out an area that would otherwise be damaged by a shovel or backhoe. The process is much simpler than other methods of digging, and it’s faster as well. In the past, there was no option except using a large backhoe to remove any dirt blocking the underground pipes, but that often caused damage to those pipes and removed far more dirt than was necessary.

A backhoe is also quite dangerous if handled improperly. Any time dangerous heavy machinery can be avoided for a job, it is best to do so. Hydro excavation methods require no heavy machinery beyond a vehicle to carry the air vacuum and water pump. This makes hydro excavation inherently safer than using heavy machines.

The only other real option beyond hydro excavation is simply digging by hand with a shovel, but that is clearly not the most efficient method. The job is physically intensive, and it requires a much larger volume of displaced soil since it is so inaccurate.

Hydro excavation eliminates the issues with standard daylighting methods of performing potholing services, and it does so in a safe, affordable way. The process is non-mechanical, making it safer, and it more accurate than any other method, so you can be sure that no resources will be wasted. Hydro excavation services are available in many locations.

The process of hydro excavation is similar to the process behind pressure washing. Water is put under incredibly high pressure and forced through a spout that channels the water into a tool for removing particulate matter from the area. The water breaks the soil apart before an air vacuum removes the soil from the hole, where it then travels to a truck-mounted debris tank. The tank is then emptied off the property in a designated dumping site.

Technology like this provides untold utility for the workers who use it. Potholing has never been easier than it is with this method, and the benefits extend to the time commitment of the project and the overall cost. Precision jobs require precision tools, and hydro excavation is as precise as possible.

The environment will also be better off with hydro excavation. Since the technique requires no heavy equipment, there are no fuel emissions to worry about. Not only that, but water is the only element introduced to the soil during excavation, making it safe for the surrounding flora. The method takes significantly less time than traditional digging methods, and it makes repairing underground facilities like sewers and pipes a breeze.

Baum Tools Automotive History in The Making

Baum Tools About Us and Our Products

Founded in Los Angeles, California in 1959, Baum Tools Unlimited, Inc. is a leading importer, manufacturer, and distributor of European automotive special tools. The company was founded by Charles Baum, who began as a tool jobber driving a VW bus all over the country and supplying Porsche and Volkswagen dealer technicians and repair shops with metric hand tools from Germany. Baum soon realized that the use of the special tools were not only time-saving for mechanics but also generating higher earnings for a repair shop. This realization led to his expanding into the growing line of Volkswagen and Porsche special tools. With the success of his customers’ businesses, Baum’s business also succeeded. With its growth through the 1960’s, Baum Tools expanded into BMW, Volvo, Mercedes, Audi, and Saab special tools.

A product cannot be returned directly to Baum Tools unless the customer contacts Baum Tools for an RA (Return Authorization) number first. The RA is valid for 30 days from the issue date. The return authorization will be cancelled if the product is not received within 30 days. No RA will be issued for invoices over 30 days old.

To begin the return authorization process, you must first submit an RA form. You can email the request to, or you can call the returns department at 1-800-848-6657 and request the form to be faxed. Upon confirmation of the RA claim, a response will be sent immediately.

In addition to invoices aged over 30 days, RA’s will NOT be issued for the following:

  • Items not purchased directly from Baum Tools
  • Items not within warranty terms
  • Items specially ordered

If there is a shipping error, it must be reported within 48 hours of receipt. There is a 20% restock fee that all returns are subject to if the tool has been unused. NO returns are accepted on used tools.

baum-tools-logoCustomers are responsible for shipping charges incurred in sending return products to Baum Tools. Products must be properly packaged and have the RA number clearly displayed on the shipping box. Any return product lacking a clearly displayed RA number will be refused and returned to sender. If damage occurs to items during return shipment as a result of insufficient packaging, Baum Tools has sole discretion in determining whether or not the product is fit for resale. Original packaging is recommended to minimize the potential for such damage.

All items returned via RA must be sent by traceable means. This would mean UPS or FedEx, for example. Retain the tracking information for your records. Returned products are the customer’s responsibility until received by Baum Tools. Credit will be issued within 10 working days after receipt of returned items.

The late 1980’s saw the introduction of advanced electronic control systems into European automobiles. Baum Tools would expand into the realm of diagnostic scan tools and quickly become the leader in the field for European diagnostic applications. Baum Tools diagnostic side (BTU Service Solutions) is a full-scale technical support and repair group in itself. We provide support through use of our scan tools, along with technical help in repairing Swedish, German, and other European automobiles with our network of specialists that are vehicle specific. If we can help you fix the issue, you’ve got a real problem on your hands.

Stahlwille Tools
The selection of high quality German hand tools for the automotive market saw an immediate expansion after Baum Hand Tools brought the Stahlwille North American distribution center to Sarasota. Stahlwille manufactures tools of the highest quality and these tools are choice for companies involved in ongoing critical manufacturing environments.

The Search For Good Technical Information
Several years ago, we began hearing complaints from many of our long-time auto repair customers who were beginning to fall behind because of a lack of available accurate repair information. There were a lot of critical holes in non-OEM information when it came to German car coverage. As a solution, we have been hosting high-end German Baum Tools auto repair seminars to keep everyone up to speed. It has always been our practice to supply an extensive manual covering the subject of each of these seminars. Over time these manuals have grown to become highly valuable publications. These manuals are now published for use in the shop. They are a must for those that work with these specific vehicles.

After encouraging some of our older, more experienced shop owners and technicians to share their knowledge and begin having seminars devoted to specific vehicle systems, we have been scheduling such seminars around the country for over four years. We schedule seminars specifically for Mercedes, BMW, Audi, Volvo, and VW. Our seminars are aimed for the experienced technicians and go deep into systems, rather than just blowing through theory. We focus on chronic problems and how to deal with them. One of the biggest benefits of these Baum Tools seminars is the networking that these technicians get to accomplish in the process. Everyone could use some kind of technical support group to pull from. A classic example of successfully pooling resources is the Bimmertech Group. We will continue to do this type of training while also enhancing our technical support group online. We look forward to someday bringing on high-end training technicians to focus on Jaguar, Porsche, and Saab. A little more help and the opportunity to network can be very valuable to anyone.
