Screw piers and pile caps are often used to support houses. What are screw piers? How are they installed? How are they used to hold up houses? What can you do if the screw pier is installed in the wrong place?
Thank you for watching!
Join Matt Cornell from Cornell Engineers for a discussion of the most important aspects of screw piers.
PS Screw piers are also known as helical anchors, screw-piles, screw foundations, helical piles, helical piers, or screw anchors. Whatever you call them, this video is for you.

Shout out to ideal Foundations who have some nice engineering drawings on their website that you might like to use when you specify their screw piers:
