In addition to standard soil mixes for different types of planting, Wheeler Zamaroni has developed these specialty soil mixes for sustainable landscaping and green building purposes:
- Bioswale Mix -
A bioswale is a low-gradient basin system which contains a dense cover of vegetation and is used to maintain and clean runoff during storm events. The gentle grade of the land slows the water flow, while the soil and vegetation filter and store runoff, removing 30% to 80% of pollutants such as petroleum products, excess nutrients, metals and sediments that may be found in stormwater. In other words, the bioswale acts like a sponge, absorbing rain water and slowly filtering and releasing it further into the ground. This promotes ground water recharge through infiltration and in turn minimizes stormwater runoff into streams and rivers.
- Rooftop Mix -
There is a growing trend in North America for turning flat rooftops of buildings in urban areas into garden oases. Rooftop gardens provide a peaceful, meditative environment and aesthetic appeal to urban properties. Made of compost, washed sand and lightweight aggregate, Wheeler Zamaroni’s rooftop planting mix is designed to provide maximum water and nutrient retention with minimum weight.
- Air Filtration Mix - Also known as biofiltration, air filtration is a pollution control method using living material (e.g. soil mixes, bark products or compost) to capture and biologically degrade process pollutants from industrial systems. The most common applications of biofiltration are processing waste water, capturing chemicals and silt from surface runoff and microbic oxidation of air contaminants. Wheeler Zamaroni is one of Northern California's premier producers of highly efficient biolfilter media. Our low pH Air Filtration Mix works by causing corrosion which eliminates many microbial species. Wheeler Zamaroni's Air Filtration Mix remains stable for decades, providing consistent airflow, back-pressure and even air distribution.
