"THE WALL" IMPACT ON CEMENT CONSUMPTION, FEBRUARY 2017
Prior to the boom period of 2004-2006 that was ignited by low and exotic mortgage rates, the cement industry averaged slightly more than 100 million metric tons of cement consumption annually. Using this level as the basis, construction of the wall as defined by PCA would amount to less than 1 percent of total national construction. The wall’s construction, however, is a regional phenomenon focusing on the four border states.
Natural barriers may reduce the coverage of the wall, given the border between the U.S. and Mexico includes rivers and mountains which account for 973 miles of border. This reduces the “wallable” border 960 miles. Natural borders include Arizona (19 miles) and Texas (954 miles). California and New Mexico have no natural borders.
