Pre-Drilling and Helical Anchors – Foundation Repair Tip Of The Day #63

Did you know there are helical anchors 12 inches in diameter??

In our previous video Brian talked about helical wall anchors and our new 3D models. In today’s #FoundationRepair #TipOfTheDay Brian discusses pre-drilling for some massive helical piles where we’re facing a hardpan layer between 6 and 10 feet this is very difficult to break through. This will help us install the 8″+ diameter helical piles to a depth of around 30 feet without hesitation. In this situation, we are using a Cat Mini Excavator to pre-drill while we’re using a Cat 323 Hydraulic Excavator to install the helical piles.

We don’t always use the big boy excavators, but when we do it’s always a fun time!
