HELICAL PIERS

The house footings will be supported by a series of 42 helical piers. Each pier is made of solid steel square stock and is "screwed" into bedrock located about 15-feet below grade in our case. Piers come in 4-foot sections and are coupled as they are sunk into the ground. Based on the results of the soils test, piers were not required per building code, but we opted to incur the incremental cost of the pier system as insurance against settling issues which have occurred to several homes in the area. Shown below is the small track-hoe used to install the piers.
