I'm planning on installing 8" glass block into an exterior concrete block wall. I'm sitting here reading the [url=https://codes.iccsafe.org/content/FRC2017/chapter-6-wall-construction#text-id-11986401]Florida Building Code on glass block[/url] and I see that section "R607.6 Sills." says: [QUOTE]Before bedding of glass units, the sill area shall be covered with a water base asphaltic emulsion coating. The coating shall be not less than 1/8 inch (3 mm) thick.[/QUOTE] Are they really implying that I should lay my glass block mortar down on top of this sealer? Does that even work? Should I use an adhesion promoter of some sort? Thanks, Steve Maring Titusville, FL

32ft long vertical wall built 60yr ago, then the sloped reinforcement added a few yr later. There are no weep holes, or french drain behind wall to relieve hydraulic pressure. What began as surface repair revealed Mother Nature relieved hydraulic pressure by creating the Grand Canyon in center of wall (see pics). Ready to start the repair, and have Q's: Should I punch a hole in the dirt under the vertical wall to lay 1.5" PVC extending behind the wall to provide a weep hole through to front of wall before pouring concrete? Idea is that that PVC runs into stone around french drain that will be added after repair. The base has a slope of 7 to 8" over 24". Will use bonding agent and Quikrete Concrete mix and add some larger stones. Will a dry mix match this slope without slumping? If not, what is recommended to slope the 7 to 8" over 24"? How deep recommend for the french drain? Water level reaches approx half way up vertical section for awhile in early spring, then most of warm months is below the sloped section to well below the wall. Thanks for your time! Surfin
