Considerations When Using Drilled Shaft Construction

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.

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.

Using Piers and Piles to Shore Up Sagging Foundations

Pier drilling and pile driving are techniques used for driving pier or piles into the ground underneath a structure to shore up sinking or sagging building foundations, bringing them back to their proper level and preventing further foundation settlement.

Also called “piering,” this method involves the use of strategically placed mechanical jacks to slowly and carefully lift the settled foundation beam to grade. Once raised, the beam is held to elevation by attaching it firmly to the piers.

There are two common types of foundation piers: Continue reading “Using Piers and Piles to Shore Up Sagging Foundations”

When to Use Helical Pier Drilling

Helical Pier drilling in the Northern California can be thought of as a system which uses anchors to secure structures to the ground when soil conditions are rather challenging, and where the usage of a more conventional foundation system is not indicated. These piers consist of a steel shaft with helicals that make it look like a very large screw, and help to secure any structure tied to it. It is especially useful for drilling where there is unfavorable ground conditions. Continue reading “When to Use Helical Pier Drilling”
