Certified Green Roof Media

Rooflite is an extensive line of especially designed lightweight soils for green roof projects. Rooflite has over 150 blends, customized by purpose and region, scientifically designed for optimum water retention and drainage, which are vital to ensure plant growth and managing stormwater.

With over 12 million square feet of Rooflite installed all over America, this is a tried and tested soil that delivers great results. Some popular uses of Rooflite range from extensive decorative green roofs to rooftop farming of vegetables, flowers and herbs.

Rooflite have designed systems to support a variety of growing needs: from rooftop lawns and sedum garden, requiring 8 inches of soil; through rooftop gardens and farming, requiring 12-14 inches of soil; and all the way to facilitating the growth of rooftop trees, which requires a multi-layered soil with a depth of 20 inches up to several feet.

CU-Structural Soil


CU-Structural Soil was 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. 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 ensure quality control and we're a licensed seller. Contact us to see if CU-Soil is the right choice for your project!

Organic-Lock™ is the strongest organic binder for aggregate surfaces on the market today. It resists erosion, is water permeable, reduces maintenance and is wheelchair accessible. It's also made from a renewable plant source.

Organic-Lock™ is designed to be blended with crushed aggregate to create natural-looking pathways and surfaces. The binder locks the aggregate in place to minimize erosion and maintenance all while remaining water permeable.

Minick Materials is proud to offer Organic-Lock to architects, landscape architects and contractors looking to create natural-looking pathways that are as durable as they are beautiful.
