The Tunnel (2013)

Episode Overview

Kevin explores Great Brook Farm State Park, a sprawling 1,000-acre site and the last operational dairy farm in Carlisle, Massachusetts. Tom demonstrates his innovative technique for crafting a custom crushed stone floor for the foundation using a "stone slinger," a powerful conveyor that can launch stone up to 75 feet. Norm supervises the setup of a new insulated foundation system, which is precast in a factory and delivered to the construction site. Meanwhile, certified arborist Matt Foti teaches Kevin and Roger how to safely relocate the septic tank while preserving an old catalpa tree that may have significant value.
