Soil that''s loose has much less bearing capacity than the original soil. That''s why it is so important to compact the trench bottom (use a vibrating plate compactor for sand or gravel soils, and a jumping jack compactor for silt or clay). If you don''t compact that soil, you could get 1/2 inch of settlement in just the first 6 inches of soil.
