Healthy roots and paved surfaces can co-exist! WSSI and The Davey Institute brought together a team of experts to discuss CU-Structural Soil® and the benefits to the urban environment.

Topics included:

  • The problem of limited soil volume for tree growth and stormwater management in the urban environment
  • CU-Soil® as a potential solution to the problem of supporting hardscapes while providing soil volume for tree root growth and groundwater storage
  • The design and installation process of a CU-Soil® project
  • Benefits and drawbacks of various systems to increase soil volume in the urban environment (based on the latest scientific research)
