Vault Access Solutions
Below Ground Access Vaults for
Municipalities and Industry

Vault Access Solutions was specifically formed to serve municipalities in need of retrofitting below ground vault locations for both wet & dry utilities including direct pedestrian and vehicle traffic conditions.

Our patented torsion assisted hinged vault access doors have proven themselves over decades of abuse from snow plow traffic in the Truckee Donner area and have overcome the problem of bolts loosening due to continuous vibration.

VAS has the solution for making the below ground vault access retrofitting unbelievably easy.  We need up to two hours for ADA compliant sidewalk installations and up to one day for roadways with heavy direct traffic.  Today, the following agencies in the State of California know this to be true: Malibu in Los Angeles County, Lancaster in Los Angeles County, Las Virginias Municipal Water District, Cucamonga Valley Water District, Golden State Water District (San Dimas, Claremont & Simi Valley),

California Water Service Co. (Torrance & Palos Verdes), Santa Cruz County Sanitation District, and City of Foster City. There are many others like these agencies who have been steadily, for the past 3 years, budgeted for the task of below ground vault retrofitting.  In doing so, safety hazards are diminishing, morale has improved among their field crews and best of all, they have realized productivity increases because of safer, quicker and easier vault access with less concern of safety hazards.

In the past year, Vault Access Solutions has been able to instill tremendous confidence about our vault access products with agencies such as: Nevada Energy (northern region), the Los Angeles Department of Water & Power, the Metropolitan Water District of California and the City of San Diego.  These municipalities will be the next generation of customers and will be budgeting annually for regular retrofitting of their below ground vault systems.

Below are short condensed videos showing the installation of two of our different style foundation frames that are shown on the Products Page.  All locations are “Built to fit”.  Some include specific needs such as the protection of an over 100 year old Redwood tree (Palo Alto) to a Water Treatment Plant clear opening size of 10ft. x 12ft. (Macon Georgia).  Don’t forget, we have no standard below ground vault sizes…Your needed size IS our standard size.

City of Palo Alto

(3 min.) – Here is a below ground vault that is a part of a sidewalk.  In this location, the growth of a 6ft. diameter redwood tree nearly destroyed the concrete vault below and the sidewalk at each end of the vault. The City used our RAF vault frame to upgrade the damaged vault structure in less than 8 hours time. The structural integrity of the below ground vault was retained.  The redwood tree was left unharmed and continues to flourish to this day.

City of Sacramento

(44 seconds.) – In this video, we are at a water treatment plant where three emergency below ground exit locations didn’t meet today’s stringent safety standards.  Each of the locations had two doors weighing in at about 500lbs each. After being retrofitted, each location now has a single 70lb. aluminum door with a handrail to address employee safety during emergencies.

City of Yuba City

(3 min.) – In this video, two men, with the use of hand tools only, replaced two pump rail guide brackets and retrofit a below ground sewage wet well fixture.  This project, from start to finish, was completed in less than three hours.

City of Foster City 


(4 min.) – Here we have a direct traffic “problem area” that had required repetitive service calls due to noise and the hazard of loose steel plates.  After removal of a 6” tall concrete extension ring and its corresponding steel frame, our direct traffic vault fixture brought peace to the neighborhood. The city has since retrofitted six similar locations and is now focusing on easier landscape locations; taking on average, one hour to remove and replace.

PG&E Central California


(3 min) – In this video, a two person crew retrofit a corner below ground vault location containing natural gas regulating and monitoring equipment.  This installation required only 1.5 hours.  This was followed by another location (not shown in the video) where the same crew retrofitted two more vaults next to each other in a little over 2 hours.

Los Angeles County, Lancaster, CA


(2 min.) – This video demonstrates the ease of sidewalk installation on a large 7ft. wide x 12ft. long new below ground vault access fixture.  Total installation time for this project was only 1.5 hours.

Macon, Georgia


(2 min.) – While the project shown in this video was not a retrofit, it provides a good demonstration of the talent that we have available to help you achieve your goals. The folks in Georgia needed a 10ft.6in. x 12ft. unobstructed, opening vault access fixture for a water treatment plant expansion. Despite the fixture’s enormous size, you’ll see a 160lb, 5’8” man open the access doors with ease thanks to our patented torsion parts. NOTE: The carbon steel bars that you see running through the center were placed for shipping purposes and removed upon installation.
