This Old House (1979)

Season 26: Episode 5

Kevin visits Great Brook Farm State Park, a 1,000-acre park and the last working dairy farm in Carlisle, Massachusetts. Tom shows Kevin how he created a custom crushed stone flooring for the foundation using a ""stone slinger"" - a high-speed conveyor that projects stone as far as 75 feet. Norm oversees the installation of a new insulated foundation system that's pre-cast in a factory and then trucked to the job site. Certified arborist Matt Foti shows Kevin and Roger how to relocate the septic tank without harming an old catalpa tree that might be worth saving.
