The TreeBunck system is a self-supporting underground growing space structure for urban trees. The system consists of modular plastic units, is resistant to heavy loads, and prevents soil compaction. The entire structure is filled with loose, nutrient-rich soil, and through the addition of oxygen and water, the tree can achieve its desired mature growth without damaging the surrounding pavement.

The UrbaCell sandwich boxes are a load-distributing and pressure-relieving system. These boxes create additional rootable volume beneath otherwise impermeable surfaces. The sandwich boxes are designed to minimize root heave; thanks to their continuous, interconnected structure, trees are less likely to cause damage to the overlying pavement.
