The Problem with Structural Soil
Many cities still use structural soil, which offers limited root space and suffers from compaction. Known as the “tree coffin”, this method results in up to 80% tree failure within 10 years.
Urban Tree Vault replaces structural soil, offering:
- Structural integrity for pavements
- 93% of the soil volume trees need to thrive
- Long-term sustainability and reduced replacement costs
