U.S. Customs and Border Protection began testing the durability of the prototypes for President Donald Trump’s border wall, a spokesman said Wednesday.

Carlos Diaz, CBP Southwest Branch public affairs chief, said agents used jackhammers and saws to test the likelihood of a breach of the wall and ropes and hooks to attempt to scale the wall planned along the border between the United States and Mexico.

The eight prototypes are between 18 feet and 30 feet high. Four are made of concrete and the rest use other materials.

Roy Villareal, deputy chief patrol agent of the San Diego sector of the existing wall, told ABC News the wall in the city has been breached nearly 2,000 times in the past three years.
