| A brief history of CU-Structural Soil® |
| |
| Based on the recognized fact that the single most important factor limiting the healthy growth of trees in urban areas is a lack of an adequate volume of soil, Bassuk and Grabosky, researchers working in the early '90's at the Urban Horticulture Institute (UHI) at Cornell University , developed the concept of Cornell Structural Coil. This evolved to become CU-Soil™, a proprietary material patented by Cornell University and marketed under the registered trademarks, CU-Structural Soil® and Cu-Soil™ |
| |
| CU-Structural Soil® was developed at Cornell University to safely bear pavement loads after compaction and still allow root penetration and vigorous tree growth by restoring the macropores in the root zone (see figure below). It is patented and trademarked under the name 'CU-Soil™'. To insure quality control, and only licensed companies are authorized to produce this material - meeting the specifications as laid down by the UHI at Cornell University. This new revolutionary urban tree mix can safely support pavements and sidewalks and is designed to provide ample rooting area for street trees, decreasing tree mortality and footpath failure. |

| This revolutionary soil mixture provides ample space for air and water movement, which promotes healthy root growth. It encourages the growth of roots underneath the pavement and reduces the buckling and cracking that often occurs with traditional and existing urban soils. |
