CU-Structural Soil Supplier

We are a licensed supplier of CU-Structural Soil

Minick Materials is a licensed supplier of CU-Structural Soil® (also known as CU-Soil®) developed at Cornell University as a way to safely bear pavement loads after compaction and yet still allow root penetration and vigorous tree growth.

CU-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-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.

CU-Structural Soil® was patented and trademarked under the name 'CU-Soil®' to insure quality control.
