Tunneling has emerged as the least disruptive and most efficient methodology for rail and vehicle transportation, clean water and wastewater security and conservation as well as security for the movement of chemicals and hydrocarbon through sensitive environments.

While the benefits of horizontal directional drilling (HDD) technology have changed the game for the utility and pipeline construction industries, the large volumes of fluid waste generated by HDD borings pose significant costs and environmental risk. Contractors and owners often choose to solidify drilling mud on site with superabsorbent polymers (SAPs) because of financial and time savings as well as SAPs’ ease of use and environmental benefits.
