Micropile underpinning in difficult soil conditions
A 1930's aerial photograph showed a large drainage ditch that appeared to have run under the corner of a structure that was built much later. Improper filling and compaction of this ditch was speculated to be the cause of a large amount of settlement under that portion of the building. Excavations revealed large boulder fill and VersaGrade chose micropiles as the most cost effective solution. The structure was underpinned and raised in excess of 6" to relieve the distress & re-level the foundation.
