Foundation walls are damp-proofed

Did you ever wonder how foundation walls are damp-proofed? With tar. Sticky, thick, black tar.

I have no pictures, as by the time Chuck and I were done applying the tar (in the sunny, 90 degree afternoon that we had today) and then using mineral spirits to remove all the splashes and spatters that got on us, I was more interested in getting a shower than taking a new progress picture.
