\u00a0\u00a0In underground construction and soil management, Horizontal Directional Drilling (HDD)<\/a><\/strong> and Vacuum Excavation<\/strong> are two widely used but very different techniques. Many clients often ask: \u201cWhat\u2019s the difference between the two?\u201d<\/em> The table below gives a simple overview:<\/p>\n
