Structural concrete panel and modular soil support system trench configurations should provide a better growing environment for trees, and thereby improve tree longevity. Structural soil medium and structural concrete panel trench configurations provide the benefits of being more adaptable to being fit around utilities or existing trees and provide easier access to utilities when repairs are needed.
