Foundation Repair Photo Album: Helical Piers install in Kamiah, ID

Helical Pier is a foundation pin made of steel that contains helices just like screws. ... Helical piers are used to support structures especially where soil conditions are challenging, making it hard to set up a traditional foundation system. Instead of expensive large excavations, they thread deep into the ground   Because the piers are pushed down to the appropriate level, it is a good choice when the condition of the soil is unknown. Helical piers, on the other hand, work well when the soil conditions are known because an installer will know exactly how far to turn the piers to reach the desired depth.
