To property owners, as well as engineers, survey monuments which last
forever and can be easily distinguished from surrounding rocks, are of
the utmost importance. Expensive re-surveys and legal fights can be
avoided by making such monuments easily distinguishable, permanent,
and in such a way as to avoid confusion with other marks. The use of
concrete for this purpose fills all the requirements better than any
other material.
Get from the proper public official (usually the county engineer or
surveyor) the exact location of corner stones. Drive four stakes in the
ground so that strings stretched between every other stake will cross
each other directly over the original monument.
Remove the old monument, and, with a post auger, bore a hole deep
enough to reach below the frost line (at least 3 feet deep), where the
old monument stood.
Fill the hole with concrete mixed 1: 2: 4, rounding the top with
the hands so it will extend 3 or 4 inches above the level of the
surrounding ground.
While placing the last foot of concrete, imbed a harrow tooth, iron
bolt, or gas pipe, with its top just showing above the finished
concrete at a point directly under where the strings cross. Protect the
monument from damage by stock for one week, by placing a box over it.
