Cognition was contracted by Magnox Ltd to carry out cement stabilisation of soil material to support the Solid Intermediate Level Waste Encapsulation (SILWE) plant which will be constructed at Hunterston A Power Station. Cognition excavated trial pits to obtain samples of the glacial till in order to carry out design testing to determine the optimum binder mix to meet a proposed allowable bearing pressure of 300 KN/m2. The works required careful excavation of soil between an existing culvert and concrete slab with dewatering to manage groundwater inundation. Excavated material was processed to remove oversize boulders and concrete which was crushed and reused as capping material above the stabilise soil. Stabilisation using a mixture of lime and cement was carried out with an excavator mounted mixing bucket with material backfilled and compacted in accordance with the Highways Specification. Plate bearing tests demonstrated the stabilised material met the design specification.
