Minick Materials is a licensed supplier of CU-Structural Soil®. CU-Soil is intended for paved sites to provide adequate soil volumes for tree roots under pavements. It can, and should 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, eliminates tripping lawsuits, and eliminates the replacement of dead trees every 7-10 years.
15-page booklet details how the combination of porous asphalt and CU-Structural Soil- reduces runoff and improves water quality. The combination allows both water and air to infiltrate the base course underneath the pavement surface. This not only allows for healthier root and tree growth, but the trees further reduce water levels through transpiration.
