IBAA was supplied from our Castle Bromwich plant in Birmingham. IBAA Type 1 and Class 1A products were used for drainage and service trench backfill on the spine roads and footpaths.  Trench reinstatement depths on site ranged between 200mm and 800mm.

The roads were dug at 800mm for the road box formation (cut and fill procedure). 6F5 Material was then installed as a capping layer inside the road box, building up for underside of kerb line and road construction to underside of base at a depth of 300mm to all main spine roads.

Footpaths also constructed after edgings were laid using the IBAA Class 1A at a depth of between 100-300mm for underside of edging laying as a capping layer under the pathway construction.


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.
