Any measures to compact the surface soil to its previous state?
The four centimetres depth of glass beads represents a 12% increase in the volume of material used to backfill Trenches A & B. Given that all the excavated material was put back in the trench when it was backfilled, and the final level of soil was the same as that surrounding the trench, the material had to be compacted, and was probably slightly more compact thean the surrounding material.
Hope that helps...
