Solutions for Dealing with Rocks During Installation

One of the most frequently asked questions we get on social media is, how to deal with rocks during a helical pier installation. The answer, of course, depends on the size and location of the rock as well as the specific circumstances of the project. In this article, we look at the different methods and solutions that Techno Metal Post uses to ensure a successful outcome.

In the case of small to medium-sized rocks, our specialized installation equipment is powerful enough to maneuver around them, allowing the pier to be installed. As the pier screws into the soil, the helix naturally displaces these rocks. Generally, if the installer comes across only a few small shallow rocks that are manageable, digging by hand is also another option for removal. When faced with very rocky land, our installers can use a specialized pier, which has been already approved by our engineering team, to bypass rock obstructions.

When the rocks are too large to be pushed or manually removed, alternative solutions are required. One such option is to install the pier right next to the rock, provided that it doesn’t deviate from the designated line and doesn't interfere with the project plans. Such relocation is always done following the approval of the project designer. However, if a large rock or boulder is obstructing the desired location and can’t be moved, it may be necessary to bring in a small excavator to remove it.

Depending on location, certain sites are composed of mainly bedrock. If the bedrock is deep enough, it can serve as a footing, provided that the helix is below the frost line. If the bedrock is shallow or even exposed, a specialized anchoring system could be used. This approach ensures that the installation remains secure and stable.

Whether it's pushing small rocks, working around large rocks, or anchoring directly to bedrock, installation professionals always find a solution to ensure a successful project.
