INNOVATIVE TUNNEL AND SHAFT SOLUTIONS
Tunnel and shaft construction requires specific in-depth knowledge and special expertise. A design-build tunnel and shaft construction company, Schnabel leverages decades of experience to provide excavation support and cut-off walls to allow for the construction of cut-and cover-tunnels and ramps, access shafts, and other underground structures.
A versatile design-build specialty foundations company, Schnabel can also provide jet grouting to stabilize the ground and reduce groundwater seepage around penetrations through tunnels and shafts. Schnabel specializes in self-supporting circular secant pile shafts that do not require bracing or tiebacks that can complicate excavation of the shaft.
