Ordering aggregates in the UK
Aggregates in the UK are typically sold in three ways: tipped loads (bulk delivery by lorry), bulk bags (tonne bags or jumbo bags, approximately 800–900kg each), and small bags (20kg or 25kg). For most DIY patios and garden projects, bulk bags are the most practical option.
A key point with sub-base aggregates like MOT Type 1 is to account for compaction - loose material compacts by 20–30% when rolled. Our MOT Type 1 Calculator handles this automatically.
