Cornell Structural Soil
Click for larger image.
Click for larger image. Structural soil was developed at Cornell University to safely bear pavement loads after compaction and still allow root penetration and vigorous tree growth. It was recently patented and trademarked under the name 'CU-Soil' to insure quality control.
For more information, see:
- New: Using Porous Asphalt and CU-Structural Soil® 15-page booklet details how the combination of porous asphalt and CU-Structural Soil® reduces runoff and improves water quality. The combination allows both water and air to infiltrate the base course underneath the pavement surface. This not only allows for healthier root and tree growth, but the trees further reduce water levels through transpiration. 1.4 MB .pdf file
