Consider These Factors When Drilling
Drilled shafts are deep foundation solutions used to support large structural loads. Also called drilled piers, caissons or bored piles, drilled shafts involve excavating soil, creating a cylindrical shaft, placing reinforcing steel in the shaft and filling the space with concrete. Drilling of this type goes back to the early twentieth century, so it is a long-established practice that has now become more common as faster and more dependable excavation techniques are being required. Pier drilling in the Bay Area makes it possible to install very deep, large-diameter shafts in many subsurface conditions, resulting in highly reliable foundation construction results.
