Geo-Soil is a high-performance, BS3882:2015-compliant rootzone soil specifically developed for use within the TreeParker® Cell System. Formulated to promote optimal root growth in heavily trafficked urban environments, Geo-Soil ensures trees establish strong, healthy root systems without risk of compaction.
Its light, friable loamy sand structure retains essential porosity, delivering the ideal balance of air, water, and nutrients while maintaining a stable, uncompacted soil layer. Whether used in streetscapes, car parks or civic regeneration zones, Geo-Soil plays a vital role in supporting long-term tree health beneath hard landscaping.
