You should talk the Viet Cong that built the tunnels of Cu Chi, the Austrian bunker dude that kept hot chicks n stuff underground, and the Taliban molemen that constructed Tora Bora. In addition to that, you should consult with a Soil Engineer, Civil Engineer, and a good Geologist to obtain construction advise specific to your job site. 86% 6 Votes
