  The hardest job I ever did was digging a French drain around my house built in 1780. The roots the roots!!!

  I&apos;ve worked construction for 30+ years, and one mantra that&apos;s served me well is &quot;you cannot stop water; you can only direct it.&quot; Forget who told me that, but I hope I thanked them.

  My childhood was plagued by a wet basement. My bedroom was in the corner. Although it was warm in the winter and cool in the summer, it was wet during the spring thaw. &nbsp;When I was 17 <a href="https://www.youtube.com/watch?v=aFZM_BY6jBw&amp;t=1001">16:41</a> , I found out that drain tiles were typically placed in the interior , but not on the exterior. The clay soil had no drainage, leaving the basement as the only place for the ground water to go. The pressure differential caused the water to seep through the concrete block walls. &nbsp;My older brother, who eventually became a mechanical engineer, earler had sealed the walls with iron oxide paint. This kept the walls dry, but it didn&apos;t keep it from finding other ways to get in. &nbsp;I solved the problem &nbsp;by digging a trench around the house down to the footer. &nbsp;I sealed the wals with roofing tar and tar paper. Then i dug channels under the footings at strategic places around the house. Then I layed down flexible drain tile surrounded with P-rock and connected it to the inner tiles. Iin order to do this, I cracked holes in the basement floor with a jack hammer. It solved the problem.

  &quot;It made a heck of a mess, pardon my French drain&quot; is one of the all time great Grady jokes 😂

  Just learned from this: here in Quebec we call them &quot;Les drains Français&quot; where we should be calling them &quot;Les drains French&quot;.

  You don&apos;t just explain the Science but &apos;Why it matters&apos;. That&apos;s philosophy in my book.

  Salt removal from agricultural land is the sort of thing that probably gets little press but is grimly important. Ancient history is full of civilizations that did not drain the farm land and simply collapsed when the salt levels exceeded what the staple crops could tolerate.

  One of my favorite fields of study is Engineering Philosophy. Questions like &quot;to what degree is the engineer responsible for protecting idiots from themselves?&quot; Based on that criteria, I would absolutely call you a philosopher, Grady. You have helped shape my perspective on engineering ethics, and I teach high school engineering, so your philosophies and opinions (no matter how mild) are permeating multiple generations of engineers. Keep up the good work!
