Chapter 10.2 Drives, pathways and landscaping

We have replaced references to the old BS Standards specification with harmonised EN Standards. References to the Highway Works specification have also been updated together with the clause on sub-base thickness. Several definitions have been added to make it easier to understand the Tables detailing pavement construction and provide clarity on limitations of flexible retaining walls. More guidance on garden areas and timber decking is also included.
