Some Simple Waterstop Formulas

I was recently in a long call with an engineer client and many of the questions he was asking, were answered directly in an old document we use to publish in our catalog. I searched through the hard-drive, found the document, converted it to a PDF, and posted it here.

This PDF contains some typical waterstop formula for placement and design considerations and some interesting information on leakage testing.
