Most new construction in my area doesn’t even include such a beast. Therefore, I wonder, in this age of new materials and techniques, what is the ‘best’ way to establish a seal between the mud sill and concrete foundation wall.
TIA

Whats wrong with sill seal? Maybe you could start a trend. That's all they use here. There's also another product that can go on after the walls are up that seals the cold joint and no I don't recall its name but it works just like window wrap. It's basically a rubberized roll, sticky on one side (EPDM?) and you stick it over the joint.
Please pardon my ignorance, but is there actually a product so named "Sill Seal" ?
Builders in my area use either nothing or a strip of fiberglass insulation 6" wide x 1/2" thick.
Sill seal is like band aid, a bunch of people make it, and there are all different types.
Where are you at where you don't concern yourself with insulation?
Wow. OK, yeah, there actually is. It's basically a roll of foam about 6" wide and I dunno, 50 or 100' rolls. It's all of maybe 1/4" thick and you just roll it out over the concrete and punch it around your anchors. When you set the plate and crank down on the anchors, it's in as good as it's gonna get. The downside is it only seals small imperfections, and even good concrete guys over the length of any foundation might give you divots more than 1/4" - which is where the other stuff comes in. It's insurance method #2 and pretty straightforward. It actually seals things up - no wind, moisture, etc, and supposedly is unfriendly to bugs too. Course, nothing says you can't double up your initial sill seal strip.
I'll take uerthane foam over anything that comes in a roll. Toatlly fills the gap, seals itself to both surfaces (if free of loose dirt), and is inert and long-lived when it's not exposed to UV.
