This is a real time saver for installing membranes!
Snap your exterior grade lines prior to pouring. Using a drywall saw cut a slit through the form at the grade line. Install the Ram-Snaps at the grade line, pour your wall as usual, simple as that, your now ready to install the membrane. Cut a small slit in the membrane with a razor knife, slide it over the Ram-Snap, place the snap on top of the membrane, and your finished!
That's easy, fast, and secures the membrane for backfill!
