Pour a cement pier - PEM BB building.sand.cementpier

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the sand badge in Building.

When building a small structure or lean-to, you will often need to put a few posts up.  Or maybe you need to support a floor structure for a tiny home or cabin.  In damp climates, posts extending into the ground are likely to rot fairly quickly.  Some options include pressure treating (ick), cement piers (ugh), big stone piers (not found everywhere) and maybe a couple other options.  Let's make a couple cement piers to keep that wood post from rotting.



Here's a team installing cement piers with a good explanation of frost heave:


Minimum requirements:
  - Create two cement piers
  - Rebar if extending above grade
  - J bolts or other attachment system embedded in top
  - Extends below the frost line for your area
  - Cylindrical in shape
  - Minimum of 18" deep into ground

Provide proof of the following as pictures or video (<2 min):
  - The place the piers will go
  - Holes dug
  - Forms in place with measurement showing depth
  - Explanation of frost depth in your location
  - Finished piers
