    Expanded Clay In Green Applications Read more +

  • Expanded clay aggregate is used in landscape restoration around our parks and the green areas surrounding urban developments. Green roof gardens act as a buffer for rainwater, which seeps slowly through the layers reducing the surge water caused by heavy rainfall. This also allows time for water evaporation, hence further reducing pressure on urban drainage systems and providing green urban areas for the Its ability to absorb gases and dust particles helps the recovery of air humidity levels in the atmosphere and improves air quality. Extensive use is made of expanded clay in drainage and water management projects and the unique structure of the aggregate systems. Leisure uses include foundations for sport surfaces and run off safety areas for motor sports. It is used in agriculture and horticulture as a growing medium for plants and even processing waste farm slurries.
