Application

For use as a tree planting soil in hard landscaping applications. Typical uses are concrete tree pits, roof tops, green zoning, central islands etc.

Description

Composed of a moist friable, slightly calcareous sand with a single grain structure, it falls into a sand texture classification. Urban Tree Soil is a medium sand with suitable levels of porosity that can be maintained, and the risk of compaction is minimized. It has good water holding characteristics and exceeds the minimum requirements for the Californian Bearing Ratio.


Urban Tree Soil should be installed at depths no greater than 600 mm, greater depths should be built up with Boughton Loam's subsoil products.


Urban tree soil is suitable for tree planting in hard landscape environments. Boughton Loam can provide additional advice if needed on how best to specific and install this soil.
