There are many different methods for installing drilled shafts, including: conventional auger drilling, slurry displaced drilled shafts, oscillation and reverse circulation, just to name a few. Every project presents its own set of challenges, which may preclude or require a certain method of installation. While means and methods are typically left up to the contactor to decide, often the site and soil conditions determine the most cost effective solution. For this reason, slurry displaced shafts have become an extremely popular method for drilled shaft construction in a wide range of soil and siteconditions.

The most common mistake contactors make in slurry displaced drilled shafts is assuming that all slurries are the same. In fact, each type of slurry is defined by a unique chemical formula and characteristics. There are minerals slurries, synthetic polymer slurries, natural slurries and enough additives to make your head spin. So, how do you choose the right one for your application? The answer is simple. Consulting with your slurry provider prior to the bidding process will ensure that you are getting the correct product for the job. This is especially true if you have adverse soil or groundwater conditions.
