Episode 17 - Lally Column Installation: Temporary versus Permanent

Okay so you've heard of dally, galley, rally, and even a girl named Sally. But what in the world is a "lally?" Well here's a history lesson. It was in the late 1800s, and a guy named John Lally was upset and bewildered by buildings collapsing as a result of fires or inadequate support. So, he was in search of a solution. Then lo and behold...in 1898, in the town of Waltham, Massachusetts, a steel beam support column was invented by none other than John Lally, hence the name lally columns. In this episode we talk about what kinds of Lally columns are out there, their problems with leaks, and how to solve water issue related to lally's.
