IBAA (Incinerator Bottom Ash Aggregate) Class 1A fill was used to blind and raise levels at a thickness of circa 50mm, prior to concrete floor slab being poured.


IBAA is an extremely cost-effective material when compared to Primary Aggregates and BP UK is working towards a verified Carbon Footprint. There are also advantages logistically when using IBAA due to the low density of the material allowing for fewer vehicle movements as this gives volumetric advantages over primary materials.
