There are a number of elastomeric membrane products made for exterior concrete decks. More important is the flashing detail that keeps the water from getting back into the building. I have read that 90% of all construction defects cases involve water getting inside the building envelope. Elastomeric membrane manufacturers should have recommended details and so should SMACNA Manual. / eric

Thanks for the replies.

I would like suggestions of how to continue the deck and achieve a
waterproof surface.  Would it be a double slab with a membrane between it?
Would it be a single slab with a walking surface membrane of some sort, a
roof designed for foot traffic as Rich Hess stated?  If so, who
manufacture's a product for this?  Is it typically made for heavy duty foot
traffic or light foot traffic?

Thanks again for your help.

Rich

Why not just continue the steel beams and concrete deck for the exterior?

Regards,

bumped off at the end of November and didn't know it for several weeks.  I
looked at the archives and saw it ended with my last few messages and

bad, I appreciated the many points of view this list server gave.  I guess
it will take some time to build it back up.

I have a project I'm designing for a camp that is a two story dining hall
and meeting room building.  The lower level is used for the meeting rooms
and the upper level will be the dining room.  The floor plan calls for a
deck outside the dining room along two sides.  The deck is about 18 feet
wide.  The architect would like the deck to be waterproof so that people can
come out of the meeting rooms below but not get wet of it is raining.  This
tends to eliminate the traditional wood deck framing because water will leak
through the gaps in the decking.
I looking for suggestions for a deck detail that can have an exterior
exposure and provide a barrier for water penetration.  The main building
floor framing will be steel beams/joists and concrete slab.

Thanks for your help.
