In cooperation with the Czech University of Life Sciences Prague, the innovative material ROOFCHAR® for green roofs and walls has been developed.
This material:
- increases the retention of rainwater in the substrate or soil, minimizes moisture fluctuations in the substrate, and reduces the need for additional irrigation
- improves the use of biogenic elements and nutrients - retains them and releases them slowly
- stabilizes (retains) contaminants and prevents their entry into plants
- increases soil microbial activity, the development of micro-organisms and the soil edaphon
- reduces leakage of nutrients (but also contaminants) into groundwater
- improves application conditions through mycorrhizal symbiosis
- sequesters large amounts of carbon in the soil (using 1 kg of biochar removes about 2.7 kg of CO2 potentially emitted to the atmosphere
The saturated material is also 5% lighter but retains 15% more water than conventional roof substrates.
