Pavement Support Systems

Not every soil structure is conducive to the growth of trees. Healthy tree growth is strongly influenced by soil structure, as it affects the movement of air, water, and other nutrients required for trees to mature. Effectively the ‘architecture of the soil’, soil structure is usually the most critical element in the success/failure of urban trees.

Too often, trees are planted in cramped planting pits and poor subsoil, resulting in stunted growth, with roots tending to colonize immediately underneath the paved surface, causing pavement damage. Without compromising or damaging the structural integrity of paved surfaces, how can urban trees be adequately provided for in their urban setting? GreenBlue offers load-bearing soil cells to create structurally adequate soil systems that are also conducive to root growth.


Rated for maximum vehicular traffic with minimal surface, RootSpace boasts the largest void space in the industry with the easiest installation process.
