BS 8640:2025 PDF

What is BS 8640:2025 - Structural and supported soils for trees in hard landscapes guide about? There is a UK-wide push for more urban trees but very little information available on suitable growing media, including structural soils. To plug that gap, and support more sustainable urban development, BS 8640:2025 gives guidance on the most successful growing medium in different situations so trees grown in hard landscapes are more likely to live long, healthy lives. Who is BS 8640:2025 - Structural and supported soils for trees in hard landscapes guide for? Users of this standard might include:

Environmental engineers; local planning authorities; community forests; tree nurseries; architects; landscape architects; developers; and landscape contractors.

What does BS 8640:2025 - Structural and supported soils for trees in hard landscapes guide cover? BS 8640:2025 gives guidance on water storage, filtration, hydraulic conductivity, fertility, pH, load-bearing capacity (where applicable), volumes, depth of material and stratification of soils to support tree growth in hard landscapes. It also covers how the material is to be placed and gives guidance on irrigation. BS 8640:2025 also examines the role of tree soils in the filtration of water and sequestration of carbon; and gives guidance on root management and on the different soil media for establishing trees in the hard landscape. NOTE: BS 8640:2025 does not replace the need for a qualified structural engineer to assess the location of the tree pit in relation to other structures; nor does it cover tree species selection. It does not detail the structures that might be used for irrigation, nor structures that might provide support for the tree or pavement. ...
