S.R.21 2014 + A1: 2016 ANNEX E - T0 - Structural
SR21 Annex E T0 General Fill is a bulk fill material produced in accordance with Transport Infrastructure Ireland (TII) specifications for unbound granular materials.
It is primarily used for non-structural backfill, landscaping, and general ground-raising applications, where strength and grading requirements are less stringent than engineered sub-base layers.
T0 General Fill provides a cost-effective solution for large-volume fill works while maintaining good compaction and stability when properly placed and compacted in layers.
This material complies with EN 13242 and is certified under S.R. 21:2021 +A1:2023 Annex E (Table E.1, T0).
