ROOFTOP GARDEN MIXES
Green roofs are part of the healthy city movement, absorbing noise pollution and creating a peaceful meditative environment with aesthetic appeal on building rooftops. Plus, they're helping to increase property values.
We blend 3 type of rooftop materials. Depths vary depending on what types of plant materials are going to be used and what teh roof weight-load is designed to handle:
- Extensive mixes are generally used at a 3" to 6" depth
- Intensive mixes are generally 6" to 12" or more in depth
- Turf mixes are 6" to 12"

RAIN GARDEN PEAT MIXES
Excellent drainage properties—Meets MPCA Stormwater Manual Guidelines
A homogeneous blend of washed clean construction sand (70 to 90%) and sphagnum peat (10 to 30%). These mixes effectively collect water from pervious and impervious surfaces while filtering out sediment and pollutants. Other benefits: Stores water for the short term to be used by plants and permits clean water to infiltrate the soil and subsoil slowly, thus recharging the ground water. See our literature sheet
RAIN GARDEN COMPOST MIXES
A homogeneous blend of washed clean construction sand (70 to 90%) and organic leaf compost (10-30%). These mixes effectively collect water from pervious and impervious surfaces while filtering out sediment and pollutants. Other benefits: Stores water for the short term to be used by plants, and permits clean water to infiltrate the soil and subsoil slowly, thus recharging the ground water. See our literature sheet
NEW IRON-ENHANCED SAND
An innovation in stormwater runoff treatment. This mix of C-33 Concrete Sand and 5% Iron Filings captures an average 88% phosphate for at least 200 m of treated depth. It offers high pollutant removal rates, is good for nutrient impaired water, can be used as a retrofit for existing areas, and is suitable for cold climates.
