The Department of Homeland Security is reviewing proposals from more than 300 companies who want to build or design the new border wall. I talked to a Tempe company that placed a bid. CMJ Systems is one of 22 Arizona companies that submitted a bid to build or design the new border wall. We’ve identified a whole different approach in being able to have a strength for a wall that’s not going to be subject to the inherent problems of steel reinforcement. He argued that his idea would be more effective than the current border fence and hopes the design for a so-called green wall will set the company apart. The idea is to use layers of recycled carpet to reinforce the concrete wall. He says the material is more sustainable and durable. Some of our preliminary testing has already proven it is it is much more dense, it’s much more stronger and and we feel that even from having explosive devices set up against it it will outperform what would be your typical tilt-up structure. The company president also estimates it would be more cost-effective to build a wall by using repurposed materials. I think that the Department of Homeland Security has to consider all options. They would not be good stewards of the taxpayers money to not look at alternatives that would be about half the cost. The Department of Homeland Security is expected to announce the finalists in June, then the selected prototypes will be built in San Diego.
