Abstract
A structural cell system is disclosed for supporting hardscape areas in a way that enables tree root growth and accommodates filtering, retention, storage and infiltration of storm water while preventing hardscape damage. The system includes a plurality of structural cells capable of being positioned below a hardscape. The structural cells are designed to have openings that are sized to accept tree roots. The system has one or more permeable barriers around the structural cells with a way for water to flow into the plurality of structural cells flow out of the structural cells.
Claims21
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.
