If Turkey and others can build a "wall" there is no reason we cannot!
Turkeys new concrete 475 Mile wall finished!.......An electronic layer consists of close-up surveillance systems, thermal cameras, land surveillance radar, remote-controlled weapons systems, command-and-control centers, line-length imaging systems and seismic and acoustic sensors.
The advanced technology layer of the project includes wide area surveillance, laser destructive fiber-optic detection, surveillance radar for drone detection, jammers and sensor-triggered short distance lighting systems.

We will have to settle for steel slats minus all the other accoutrements especially the remote-controlled weapons systems ... if we are lucky.
