Micro tunneling is trench less pipe installation by remote-controlled jacking. Thanks to DFHB technology, pipes of high compressive strength, various wall thicknesses and consistent superior quality can be manufactured to routinely & safely withstand the jacking forces required for a variety of project conditions and anticipated drive lengths.

 

Due to the smooth, non-absorbing exterior surface, tight OD tolerances and lighter weight construction, DFHB Jacking Pipe Systems experience the lowest jacking loads in the industry. The lathe cut square ends and natural material resiliency, mean DFHB Pipes transfer jacking loads with better distribution, and more forgiveness, than any other sewer product, thereby resulting in the highest reliability available. DFHB Jacking Pipe Systems are available from many factories around the world in a wide diameter range.
