Strengthening of Equipment Foundations on Loose Soils of a Power Plant in Eastern Uttar Pradesh

Small equipment foundations of a power plant placed on a 5–6 m thick poorly compacted fill underlain by rock experienced excessive settlements. Strengthening measures adopted included installing micro-piles extending to the top of rock and filling large voids in the fill with a thick grout of cement and sand. This highlights the importance of proper compaction as well as the need to test the bearing strata adequately before constructing foundations on fill.
