Construction of Piling Mats

IBAA is extremely cost effective and there are advantages logistically when using IBAA due to the low density of the material, meaning fewer vehicle movements when compared to Primary Aggregates.

Material Requirements

Groundwork involved the construction of 800 piles for ground stabilisation prior to construction of two new sewage tanks. A piling mat had to be created sufficient to hold a Junction PM26 Vibrocat piling rig. After an incremental settlement test on IBAA Type 1 a reading of 10mm at 800KN load was achieved and found to be within guideline limits of up to 12mm. IBAA Type 1 was nominated and specified as the preferred suitable fit for purpose aggregate to be used on the contract.
