Always very cool to see, especially considering how many others would just as soon roll over it with a dozer.

Admiration. I aspire to do this type of work someday.
What type of glue do you use for stone?

I used a high grade construction adhesive Liquid Nails. The weight of the top stone provided a lot of pressure to bond them together. Then used a high grade silicone around the outside cracks after placing the angle irons on the sides.

Beautiful work.

How well did the elevation of the stone match when you did the 3-wire run?

The original mark is now technically destroyed. Will you be filing a RESET on it to get a new PID, or does that process even work nowadays?

Two thoughts about stability - Is packed sand sufficiently stable against settling? Will the concrete around the stone lift it up when water freezes under the concrete?
