Clean Cover System

The Green-tree Clean Cover System offers a remedial and effective solution for the development of brown-field sites.


By incorporating the Green-tree Clean Cover System into initial plans, the project can progress with reduced excavation works yet provide a suitable long-term solution for the development. Utilising a cover system will reduce the hazard to human health or the environment from potential contaminants found on brown-field sites, providing a suitable growing medium for plant and tree growth. The Green-tree Clean Cover System is a combination of manufactured British Standard Topsoil and Subsoil which are both chemically clean. This provides a
growing medium that is tested to CLEA requirements, with very low-level chemical, metal and metalloid content and clear of asbestos content.
