If you drive east from the Pentagon on South Hayes Ave in Arlington, you’ll see more than 6,000 square feet of Flexi-Pave in the medians. Project was completed on April 24, 2014.

A Flexi-Pave sidewalk was installed at Woodbury Park Apartments in Arlington, VA on April 14, 2014. Chosen Flexi-Pave color was Mossy Slate. For this job, preparation included installing a stone base and soil excavation using the super sonic air tool (SSAT) around tree roots. For more information on the super sonic air tool click on www.supersonicairknife.com.
Check out the link above as their website has a great description of the device and lots of technical info: The supersonic air knife is a “Hand held tool that converts compressed air from a portable compressor to a supersonic jet stream that is used to dig safely in the ground, without damage to buried gas pipe lines, tree roots, sewer pipes, and other non-porous objects…Applications of the supersonic air tool include:
-Trench Rescue
-Tree Root Arborculture
-Locating Buried Utilities
-Oil Spill Abatement
-Locating Septic Tanks
-Cleaning Earth Moving Equipment
-Shallow, Small Pipe Placement
The technology behind the air knife: “Compressed air, typically 90 to 100 psi, is converted to a supersonic jet while flowing through a nozzle especially designed for the purpose. The maximum jet velocity that can be achieved is determined by the pressure available from the compressor. Exit velocities in the range of mach 1.6 to mach 1.7 are typical for most portable compressors. Since the determining limit on mach number for the exiting jet stream is the available pressure, higher mach numbers can only be achieved by using higher compressor pressures. Since the emerging jet stream diameter is the same as the nozzle exit diameter, the air stream is initially the same diameter as the nozzle exit. For this reason, some refer to this characteristic as being laser-like. But as soon as the stream leaves the nozzle, it expands concentrically, since it is surrounded by atmospheric air. High speed video shows this rapid expansion, but it also shows that this high velocity air penetrates the ground to a depth of about a foot, creating a momentary cavity of about a foot in diameter, in which the dirt is crumbled. As the jet leaves that location or the air blast is ended, the dirt falls back on itself if the tool barrel is held close to the vertical. If the Air Knife barrel is inclined away from the user, the dirt can be blasted out the ground to a depth of one to two feet, depending upon technique. Since buried pipes, cables and tree roots are not porous, the dirt is removed from them and they are not damaged.”

Flexi-Pave Over Critical Root Zone Detail
On April 3, 2014, Georgetown approved Flexi-Pave for widespread use in the tree surrounds throughout the historic district. This tree grate in front of the Godiva Store, may be the next scheduled to be upgraded to the revolutionary new flexible pervious paving material Flexi-Pave.
In a city wide effort to repair broken sidewalks throughout Washington DC, the District Department of Transportation (DDOT) is systematically replacing failing sidewalks. And in areas where tree roots are the culprit, the Urban Forestry Administration (UFA) and DDOT have created a new standard. Flexi-Pave ADA accessible sidewalks have been used for over a year now to solve this problem. So Flexi-Pave has become the new standard for dealing with trees and sidewalks. Every week Capitol Flexi-Pave crews are installing Flexi-Pave somewhere in the District. Check the Installation Map or the Projects Page for the most current information on where we’ve been working.
The CityCenterDC Rooftop Dogpark was completed in March 2014. Flexi-Stone color chosen was River Rock.

In February of 2014 we installed a Flexi-Pave sidewalk at George Washington University. Chosen Flexi-Pave color for this 384 square-feet sidewalk was Cabernet.
