Urban Tree Soil
Urban Tree Soil from Enrich is an engineered structural soil designed to support healthy tree growth in streetscapes, paved areas, central islands and other urban environments where conventional topsoil volumes are limited.
Also known as Amsterdam soil, Urban Tree Soil is formulated for locations where trees must establish successfully within constrained planting areas surrounded by paving, roads or other hard surfaces.
The engineered soil structure provides improved drainage, stability and oxygen movement through the root zone while maintaining access to moisture and nutrients. This helps create healthier growing conditions for trees in environments where conventional compacted soils can restrict root development.
Organic matter within the blend supports soil fertility and biological activity, helping young and established trees develop stronger root systems and improved long-term resilience.

Structural Soil for Urban Tree Planting
Urban tree planting presents a different set of challenges to conventional landscape planting. Trees must often establish within narrow pits, paved streets and heavily trafficked public areas while still receiving enough air, water and usable soil volume for healthy root development.
Enrich Urban Tree Soil is designed to provide a stable growing medium capable of supporting both the tree and the surrounding urban environment.
Improved Drainage and Root Aeration
Compacted urban soils can restrict oxygen and water movement through the root zone, reducing the ability of trees to establish successfully. A well-engineered structural soil helps maintain pore space so that roots can access air and moisture more effectively.
Improved drainage also reduces the risk of prolonged waterlogging while helping water move through the planting area in a controlled manner.
Urban Tree Soil for Streets and Public Spaces
The product is suitable for tree pits, streetscapes, central reservations, plazas, public realm projects and other locations where trees must coexist with paving and engineered surfaces.
Creating sufficient high-quality rooting volume can improve tree health, longevity and resilience while reducing some of the problems associated with poorly structured or heavily compacted urban soils.
Supporting Sustainable Urban Infrastructure
Healthy urban trees provide important environmental benefits including shade, biodiversity, carbon storage, evapotranspiration and interception of stormwater.
When integrated into Sustainable Drainage Systems and green infrastructure projects, appropriately specified tree soils can help combine effective stormwater management with long-term landscape performance.
Urban Tree Soil Supplied in Ireland
Enrich supplies engineered urban tree soils for landscape architects, local authorities, civil engineers, developers and contractors throughout Ireland.
Soil solutions can be specified for new streetscapes, public realm improvements, urban regeneration schemes and other projects requiring reliable growing conditions for trees within constrained urban environments.
