A Guide to Helical Pulldown Micropiles – Part 2
Updated: Feb 22, 2021
In Part 1 of our 2-part post covering helical pulldown micropiles, we talked about how easy the installation process is. Now we’ll go into detail regarding the numerous advantages for using Helical Pulldown Micropiles from CHANCE instead of other foundation systems:
Ideal for multiple applications: As we noted in part 1, helical pulldown micropiles can be used in a variety of situations – including limited access sites, new structures being built on poor surfaces, in addition to underpinning work on an already built structure that’s starting to settle.
Wireless torque indicator: Installations of Helical Pulldown Micropiles from CHANCE can be used with the wireless torque indicator. The indicator allows the installer to get a true idea regarding the anchor holding capacity, in addition to making sure that not too much pressure is applied – something that could harm the anchor itself.
Minimal soil disturbance: The screw anchor is designed to provide minimal disturbance to the ground. It’s different from traditional augers because it features less bearing plates – making it not only go in easier, but allowing it to have less of an effect on the soil itself. In the case of the helical pulldown micropile, less bearing plates actually means more. The screw anchor is further fortified through the use of grout from reservoir.
Require less labor: Helical pulldown micropiles are less labor intensive compared to other foundation installations. They’re specifically designed to be handled by small construction crews – meaning just a few people.
Address different soil types: The design of the screw anchors is designed to address a variety of soil types – whether they are weak or more compact.
Easy to install: Helical pulldown micropiles are relatively easy to install. The helical shape of the screw anchors is designed so that crews aren’t required to remove any soil from the construction site.
