I'm building a new house. My front porch is going to be a suspended slab over a storage room in my basement (10" poured concrete walls). The porch upstairs is a 6' deep porch by 44' wide. I'm using 2" deep corrugated metal with a w" pad over the top of the ridge. The front edge of the concrete will be formed over the front of the porch to create a 2" ledge for the stone siding to come up under. The front porch is completely covered from end to end and there is pretty much a natural wind/ weather break from a stand of boulders and trees about 15-20 feet from each side of the house.
Now you know the project...here's my plans...I want to keep the storage room relatively dry. I know nothing in this situation is ever 100% but I'd like to keep it close.
1. I wanted to run a bead of sealant between the expansion joint and the house.
2. They have a foam strip that has "barricades" that close up the cells in the corrugated panels. I was planning to silicone those in place. Then when I flip the panels into place, I was going to put down a thick bead of silicone between the masonry and the foam on the bottom of the panel barricades. Put silicone between the panels as I overlap them.
3. (This step was advice from another contractor and wanted to get input here) Get a good thick vapor barrier and lay it over the metal. Take some masonry sand and or pea gravel and put just enough of it in the groves to hold it in place. Run the plastic up the wall on the house side 6-8 inches. On the sides and front, cut the barrier where it comes just over the edge of the wall and if I want I can seal that as well with caulk....I know...small fortune in just caulk :vs_laugh:
4. Once the concrete is poured they were already plan on sealing it by practice due to the fact it's being stamped and stained.
5. Prior to siding...installing a piece of copper flashing that will come out and over the expansion joint and you guessed it...I'm not even going to say it! :vs_smirk: The copper flashing also ties in with the rest of the siding. Instead of a capstone on the rock walls, I'm going with a lip of copper all the way around. It's less expensive and I've seen some really nice work with it in my area. I know...cheaper isn't always better...but this was actually recommended by the masonry company as well because even he thinks the cost of the cap stones are nuts :vs_whistle:
6. Last but not least is there will be electrical in this area. As a Fail safe I'm still keeping a dehumidifier in there.
So...thoughts...advice...overkill...nut job (my wife says that so I won't be offended :vs_laugh
