Abstract:
1. A multilayered structural cell system for supporting hardscape areas that enables tree root growth and accommodates filtering, retention, storage and infiltration of storm water while preventing hardscape damage, comprising; a first layer of structural cells positionable below the hardscape, the first layer of structural cells are short term water storage cells; water ingress into the first layer; a second layer of structural cells positioned below the first layer, and including tree-rooting medium supporting the normal growth of structural roots within the second layer of structural cells; wherein tree-roots penetrate the second layer through openings in the structural cells sized to accept the tree roots from a tree external to the structural cells; a third layer of structural cells positioned below the second layer, the third layer of structural cells are long term water storage cells; water egress from the third layer of structural cells; a first permeable barrier separating the first and second layers; a second permeable barrier separating the second and third layers; and each of the layers being in fluid communication with the other layers.
