All,
Can anyone point me in the right direction regarding the requirements for secondary containment for facility piping.
The piping varies in size and is steel/metal pipe. Some of the pipe has threaded fittings, some is welded.
Thanks for all your help.

I work for a Precast Concrete Company. We currently use wet cast concrete, and I would like to know more about Dry Cast Concrete. Pros/Cons anything relevant.
Thanks
