Conte Company helped create the Hubbell-Chance displacement pile product known as Drivecast™.
If you haven’t considered grout displacement piles for your project, you really should. There are many benefits to using such a system and more testing and performance data is produced each-and-every day. Here’s a little background on the product and how it performs, which explains why we’re so excited to tell you about it.
This patented grouted displacement pile was designed to be used in high side friction and end bearing applications. This combination of load carrying capacity allows the pile to be used in most soil conditions and load requirements. The added rigidity and larger grout shaft resist buckling and high lateral loads, where segmental piles systems wouldn’t normally be considered. Since each coupling joint is completely encased in grout, the finish pile acts as one solid piece in the soil.
During early Spring of 2018, Conte Company performed a load testing program that compared Drivecast piles to traditional driven and helical piles. (8) different piles were installed within the same site, to a similar depth. These piles were all tested in compression and lateral resistance. We even used a tell-tale testing method on one of the Drivecast piles—which is a method for isolating the side friction from the end bearing resistance of a pile. The results were extremely interesting and educational.
- The (3) different Drivecast size piles outperformed the (3) driven piles and (2) helical piles in compression
- Two of the Drivecast piles were laterally tested during a week of torrential rainstorms and they still held respectable numbers
- The RS4500DC pile achieved the largest of the group at over 20 kips
With the help of GZA GeoEnvironmental, Inc., the results of all the testing were cataloged and evaluated. You can download the full report here. We would like to extend our deepest gratitude to King Industries, Inc. for offering the use of their property for the testing location. We would also like to give a special thanks to Gary and Charlie Wetmore at G&C Marine for bringing out their new blow hammer to help with the driven pile installation!
