CU-Structural Soil

Eagle Lake Professional Landscape Supply is a licensed supplier of CU-Structural Soil® (also known as CU-Soil®) (U.S. Patent #5,849,069), a soil designed by Cornell University to improve the growth and development of urban trees.

Developed as a way to safely bear pavement loads after compaction and yet still allow root penetration and vigorous tree growth, CU-Structural Soil® is intended for paved sites to provide adequate soil volumes for tree roots under pavements. It may be used under pedestrian mall paving, sidewalks, planting islands, and parking lots. CU-Structural Soil® is an innovative medium installed under pavement that improves street tree vigor and prevents sidewalk failure, frequent pavement repair, virtually eliminates tripping lawsuits, and greatly reduces the replacement of dead trees every 7–10 years.
