As major communications corporations respond to the demand for data, they are building out massive networks of fiber in areas of existing under- and above-ground infrastructure, making trenchless technologies the method of choice. For shorter runs often seen in residential projects, HammerHead Mole® piercing tools offer a fast, cost-effective solution. These missile-shaped pneumatic hammers require only a small launch pit to install fiber optic cable under obstacles such as driveways, roads and sidewalks. For longer lengths of cable, Horizontal directional drilling (HDD) is the preferred installation method. For HDD projects in rocky ground conditions, HammerHead® Trenchless built upon our foundation in pneumatics to produce Roughneck Rock® Hammers which enable virtually any directional drill to install service and main lines through solid rock.
