The wall will be based on the eight prototypes recently constructed outside San Diego. The models recently underwent rigorous testing by special operation teams from El Paso and Florida.
According to those familiar with the tests, the walls withstood cutting torches, jackhammers and concrete saws better than anything currently on the border, and were almost impossible to climb, thanks to anti-climbing and anti-perching features.
“I can’t talk about it,” said a DHS official in Washington. “But the walls were so high we had to suspend testing. It was unsafe. Out of dozens and attempts, one guy made it to the top but he couldn’t get down. We had to bring him down with cherry picker.”
The test results are secret and won’t be revealed for another two to three months, sources say. But after multiple interviews with Border Patrol sources, here are a few key takeaways.
Among the eight designs, agents still prefer the see-through bollard style fence, topped with a flat concrete or steel anti-scaling mat. Agents say a 30-foot-high fence may not be necessary, 24 feet might be acceptable to save a few dollars.
