The picture of this sidewalk is one of the many examples of what happens with impervious materials like non-porous concrete and asphalt. This tree can’t breathe and get what it needs to survive so it creates what we call “knees” on the roots that work their way up to the surface to get what it needs to survive. With Flexi-Pave this will not happen as Flexi-Pave is porous so the trees get what they need (air, water, nutrients) and they will not have to hatch an escape plan.
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.
