And finally, the UK National Annex to EN 1997-1 states:

'In the UK, the design and execution of reinforced fill structures and soil nailing should be carried out in accordance with BS 8006, BS EN 14475 and prEN 14490.'15

EN 14475 was published by CEN in 2006 and is due for systematic review by TC 288 in 2011. A corrigendum was issued in 2006.

15.3.5 Soil nailing

At the time of writing (early 2008), development of EN 14490, which will deal with the execution of soil nailing, has not reached completion and the document is only available as pre-standard prEN 14490.16 Publication of EN 14490 is expected before 2010.
