Borros Point
For Single-Point Settlement Measurement
A borros point consists of a three-pronged anchor, a 1/4" inner pipe,
and a one-inch outer pipe, both steel. The inner pipe is attached to
the anchor and is free to move inside the one-inch pipe.
A precision leveling survey is used to determine the elevation of the
top of the inner pipe. Changes in its elevation indicate an equivalent
amount of settlement or heave in the ground around the anchor.
