Among the longest-established trenchless installation methods is the use of pneumatic piercing tools: an option that has been providing contractors with a cost-effective and easy-to-use alternative to trenching for nearly half a century. Water, gas, sewer and electrical interests have all benefited from this established and proven underground method, which also serves as an efficient alternative to larger directional drilling equipment. As is the case with nearly every installation approach, piercing tools are most effective when used in specific situations.
As a professional excavator, if you are digging or placing any object in the ground, you are required to get marks indicating the location of underground utilities. The person doing the excavating is the person that has to make the call.
Since the inception of horizontal directional drilling (HDD) in the late 1970s, there have been remarkable advances in the technology and equipment that serves the trenchless construction industry. The equipment in the early 1980s was basic and not designed specifically for HDD, nor was it particularly reliable.
