Pier drilling is an effective way to provide a strong and secure foundation for a Bay Area structure, especially in areas where the ground is less stable. As its name suggests, pier drilling consists of creating a shaft in the ground which is bored with specialized machinery, after which it is usually filled with concrete to add strength and stability to the foundation. This kind of drilling or excavation can be at normal depths or it can involve deep foundation drilling, when extra depth is needed to reach stable ground for a larger structure.
Straight Piers vs. Bell Piers
In this type of pier drilling, a dirt augur is often used to bore straight down into ground which may contain natural obstacles or is simply very hard drilling to get through. It is sometimes necessary to drill to a depth where a favorable geologic zone exists for installation of the pier, otherwise drilling depth is generally pre-determined by foundation requirements. With straight piers, the load-bearing capacity may be sourced almost entirely at the end bearing (the bottom of the shaft), or there may also be some load-bearing capacity developed by side-wall friction, if the soil is suitable for that.
This kind of pier drilling is used when it is necessary to provide a great deal of support to a very large structure on the ground surface. It starts out much like a straight pier, but when the desired depth is reached, an additional tool with expandable wings is used at the bottom of the shaft to hollow out a greater area. This gives it the bell shape, and it creates a pier which can provide greatly increased load capacity to the structure above.
