We have experience tunneling through all types of ground conditions under roadways, buildings, railways, and natural features utilizing a wide array of tunneling techniques.
Micro-Tunneling, Tunneling, Pipe Ramming, Directional Micro-Tunneling, Shaft construction and shoring are all different tunneling methods that our teams and affiliates have used.
Since the tunneling process doesn’t require a surface entry and exit point, the overall crossing length can be reduced dramatically and thus there are very few limitations to a tunnel’s size.
Ground water, unconsolidated formations, subsurface debris and restricted workspace are also challenges that tunneling methods can be used to overcome.
Tunneling techniques are best used when the crossing distance is short, the pipe diameter is large and the construction footprint does not allow for an entry and exit angles.
