CU-Structural Soil® (U.S. Patent #5,849,069) is a soil designed by Cornell University to improve the growth and development of urban trees. A lack of useable soil volume for root growth and soil compaction has lead engineers to create a load-bearing soil that can be used along sidewalks. The soil is comprised of rigid stone, heavy clay loam, and Gelscape® hydrogel as a non-toxic, non-phytotoxic tactifier. GS&G is the sole licensed manufacturer in the Eastern-Ontario region.
