Trenchless Technology Design 
In recent years, trenchless technology has come to the forefront of the underground construction industry as an economical and environmentally friendly alternative to cut-and-cover pipeline construction.

Throughout our history, Haley & Aldrich has applied trenchless technologies, from small diameter pipe jacking to large diameter tunneling, to a wide range of construction challenges. Our team has successfully applied trenchless construction methods on pipeline projects throughout the U.S. and abroad involving auger boring, pipe jacking, pipe ramming, microtunneling, pilot tube microtunneling, horizontal directional drilling (HDD), and rock, soil and mixed-face tunneling.
