Seriously, what are you going to build it out of?
The berlin wall as 12 feet tall, and made out of reinforced concrete. It was reinforced by mesh fencing, signal fencing, anti-vehicle trenches, barbed wire, over armed watchtowers, and twenty bunkers with garrisoned troops.
Troops willing to shoot to kill.
it was less than a 100 miles long, and still cost 16,155,000 East German marks to build, leaving aside maitenance costs.
People STILL made it over.
The us/mexico border is 2 *thousand* miles.
Unless you actually garrison/heavily patrol the border, any physical wall can be compromised by destroying it or just piling a truckload of sandbags on one side.
Never mind the fact that our economy would probably implode if agri-business had to actually start paying market wages for seasonal workers.
