Hi Guys,
This mount install is not on a flat roof, well a few hundred sq feet
are, but mostly on some tilt.
Also they do get hurricanes there, so not sure how well the ballasted
work in that high of wind.
As to the construction, not of my choice anyway. I've never see in
here in the US but in MX or Baja at least its common.
Quicker than standard blocks and lots of insulation in the middle.
So I think I really looking at in concrete anchors, and am leaning
towards epoxy style.
Thanks,
jay

Hi Jay,
not having any experience with these roofs (what a weird way to
build a roof) if you're doing a flat or near flat mount, I'd look at
the currrent issue of Solar professional magazine. lots on flat
roof mounts.
Ballasted is probably going to be your best bet.
if a high tilt (hot water system? ) I'd recommend either core
drilling thru the concrete/foam sandwich and bolting a pipe leg to
the bar truss underneath. then have a roofer (roofer of record if
you can find them) or a roofer with experience with that roofing
system flash the pipe legs.
I'm mostly hot water, and so deal with higher tilts and wind loads
than most of you lucky PV guys.
