[CANUFNET] Floating sidewalks or slabs over tree roots

[Naomi Zurcher]

Hi Philip:

Since these are existing roots, how are the Permavoid modules being incorporated into an existing rhizosphere. I know Silva Cells and I have never seen a successful retrofit using them so I am wondering how this is being managed with Permavoid?

Thanks
